+1. Unpack the downloaded  archive of gl2ps product (e.g. *gl2ps-1.3.5.tgz*) into the *3rdparty*  folder. 
+
+   As a result, you will get a folder named, for example, *3rdparty\\gl2ps-1.3.5-source*. 
+
+   Rename it into <i>gl2ps-platform-compiler-building mode</i>, where 
+   * **platform** -- *win32*  or *win64*; 
+   * **compiler** -- *vc8*, *vc9* or *vc10*; 
+   * **building mode** -- *opt*  (for release) or *deb* (for debug). 
+   
+   For example, <i>gl2ps-win64-vc10-deb</i>
+
+   Further in this document,  this folder is referred to as *gl2ps*. 
+
+2. Download (from http://www.cmake.org/cmake/resources/software.html) 
+   and install the *CMake* build system.  
+
+3. Edit the file *gl2ps\\CMakeLists.txt*. 
+
+   After line 113 in *CMakeLists.txt*: 
+
+       set_target_properties(shared PROPERTIES  COMPILE_FLAGS \"-DGL2PSDLL -DGL2PSDLL_EXPORTS\")
+    
+   add the following line:

+       add_definitions(-D_USE_MATH_DEFINES)  
+
+   Attention: If Cygwin was installed on  your computer, make sure that there is no path to it in the *PATH* variable to avoid possible conflicts during the configuration. 
+
+4. Launch CMake <i>(cmake-gui.exe)</i> using  the Program menu. 
+
+   In CMake: 
+  
+   * Define where the source code is. 
+     This path must point to *gl2ps*  folder.

-@section occt_debug_sanitizers Use of compiler sanitizers
-
-GCC and Clang compilers provide options for instrumenting the code with the tools intended for detection of run-time errors, called sanitizers.
-This section provides some hints for using sanitizers for detecting possible errors in OCCT code.
-
-@subsection occt_debug_sanitizers_linux Linux
-
-Example of configuration steps for Ubuntu:
-
-1. In CMake configuration:
-
-  - Use up-to-date version of the GCC or CLang compiler; make sure that if CMAKE_CXX_COMPILER is set to C++ compiler (e.g. "clang++-6.0") and CMAKE_C_COMPILER is set to C compiler (e.g. "clang-6.0")
-  - Ensure that CMAKE_LINKER is set to the C++ linker bundled with compiler (e.g. clang++-6.0); this is important to avoid linking problems
-  - For building with Address sanitizer, set CMAKE_CXX_FLAGS and CMAKE_C_FLAGS to "-fsanitize=address -fno-omit-frame-pointer -fno-optimize-sibling-calls"
-  - For building with Undefined Behavior sanitizer, set CMAKE_CXX_FLAGS and CMAKE_C_FLAGS to "-fsanitize=undefined -fno-omit-frame-pointer -fno-optimize-sibling-calls"
-  - Set CMAKE_BUILD_TYPE to RelWithDebInfo to get more informative stack traces on errors
-
-2. Build as usual (make)
-
-  Be prepared that it works much slower than normal build and consumes more disk space.
-
-3. Before running executable, make sure that "llvm-symbolizer" is in PATH; this is necessary to get human-readable stack traces. The tool must have exactly that name.
-
-  If it is installed in common folder (/usr/bin or similar) with different name, one option is to create a symlink, for instance:
-> sudo ln -s /usr/bin/llvm-symbolizer-6.0 /usr/bin/llvm-symbolizer
-
-  Alternatively, add directory where actual llvm-symbolizer is located (such as /usr/lib/llvm-6.0/bin) to the PATH variable. 
-
-4. Set environment variable to disable memory leaks detection (they seem to be reported for every global variable at exit, not much useful):
-> export ASAN_OPTIONS=detect_leaks=0
-
-5. Set environment variable CSF_CPULIMIT_FACTOR to reasonably large number to increase the time limits for program execution (used by OCCT tests) to compensate the performance penalty introduced by sanitizers:
-> export CSF_CPULIMIT_FACTOR=20
-
-6. When using UBSan, set environment variable UBSAN_OPTIONS to get stack traces:
-> export UBSAN_OPTIONS=print_stacktrace=1
-
-7. Run DRAW and perform tests as usual, keeping in mind that running with sanitizer is much heavier than normal build:
-> ./draw.sh relwithdeb  <br>
-> Draw[]> testgrid -parallel 0
-
-Note that when running tests under sanitizers, behavior may be different.
-Known problems (as of CLang 6.0) are:
-- Software signals (access violation etc.) are not handled
-- Heap memory usage always reports zero
-
-@subsection occt_debug_sanitizers_windows Windows
-
-Though CLang toolset is available in Visual Studio 2015 and newer, sanitizer do not seem to be available out of the box (last tested with VS 2019 16.2.3).

 It is necessary to introduce the corresponding changes in the applications for which the order of sub-shapes resulting from a Boolean operation is important. It is strongly recommended to use identification methods not relying on the order of sub-shapes (e.g. OCAF naming).
 * If you need to use OCCT on Mac OS X with X11 (without Cocoa), build OCCT with defined pre-processor macro *CSF_MAC_USE_GLX11*. XLib front-end (previously the only way for unofficial OCCT builds on Mac OS X) is now disabled by default on this platform. If your application has no support for Cocoa framework you may build OCCT with XLib front-end adding *MACOSX_USE_GLX* macro to compiler options (you may check the appropriate option in WOK configuration GUI and in CMake configuration). Notice that XQuartz (XLib implementation for Mac OS X) now is an optional component and does not provide a sufficient level of integrity with native (Cocoa-based) applications in the system. It is not possible to build OCCT with both XLib and Cocoa at the same time due to symbols conflict in OpenGL functions.

 * Calls of *Graphic3d_Group::BeginPrimitives()* and *Graphic3d_Group::EndPrimitives()* should be removed from the application code.
 * Application functionality for drawing 2D graphics that was formerly based on *TKV2d* API should be migrated to *TKV3d* API. The following changes are recommended for this migration:
    * A 2D view can be implemented as a *V3d_View* instance belonging to *V3d_Viewer* managed by *AIS_InteractiveContext* instance. To turn *V3d_View* into a 2D view, the necessary view orientation should be set up at the view initialization stage using *V3d_View::SetProj()* method, and view rotation methods simply should not be called.
    * Any 2D graphic entity (formerly represented with *AIS2D_InteractiveObject*) should become a class derived from *AIS_InteractiveObject* base. These entities should be manipulated in a view using *AIS_InteractiveContext* class API.
    * All drawing code should be put into *Compute()* virtual method of a custom interactive object class and use API of *Graphic3d* package. In particular, all geometry should be drawn using class hierarchy derived from *Graphic3d_ArrayOfPrimitives*. Normally, the Z coordinate for 2D geometry should be constant, unless the application implements some advanced 2D drawing techniques like e.g. multiple "Z layers" of drawings.
    * Interactive selection of 2D presentations should be set up inside *ComputeSelection()* virtual method of a custom interactive object class, using standard sensitive entities from *Select3D* package and standard or custom entity owners derived from *SelectMgr_EntityOwner* base.

-@subsection upgrade_730_replace_CDM_MessageDriver_interface_by_Message_Messenger Unification of the Error/Warning reporting system of Application Framework
-
-Class *CDM_MessageDriver* and its descendants have been removed; class *Message_Messenger* is used instead in all OCAF packages.
-By default, messenger returned by *Message::DefaultMessenger()* is used, thus all messages generated by OCAF are directed in the common message queue of OCCT.
-
-In classes implementing OCAF persistence for custom attributes (those inheriting from *BinMDF_ADriver*, *XmlMDF_ADriver*), uses of method *WriteMessage()* should be replaced by call to method *Send()* of the inherited field *myMessageDriver*. Note that this method takes additional argument indicating the gravity of the message (Trace, Info, Warning, Alarm, or Fail).
-
-Class *Message_PrinterOStream* can be used instead of *CDM_COutMessageDriver* to direct all messages to a stream.
-If custom driver class is used in the application, that class shall be reimplemented inheriting from *Message_Printer* instead of *CDM_MessageDriver*.
-Method *Send()* should be redefined instead of method *Write()* of *CDM_MessageDriver*.
-To use the custom printer in OCAF, it can be either added to default messenger or set into the custom *Message_Messenger* object created in the method *MessageDriver()* of a class inheriting *CDF_Application*.

-*SelectMgr_SelectingVolumeManager::Overlap()* methods have been corrected to fill in *SelectBasics_PickResult* structure (depth and 3D point) instead of only depth value, so that custom *Select3D_SensitiveEntity* implementation should be updated accordingly (including *Select3D_SensitiveSet* subclasses).
-
-@subsection upgrade_740_ocafpersistence Document format version management improvement.
-
-Previously Document format version restored by *DocumentRetrievalDriver* was propagated using static methods of the corresponding units (like *MDataStd* or *MNaming*) to static variables of these units and after that became accessible to Drivers of these units.
-Now Document format version is available to drivers via *RelocationTable*. The Relocation table now keeps *HeaderData* of the document and a format version can be extracted in the following way: *theRelocTable.GetHeaderData()->StorageVersion()*.
-Obsolete methods: *static void SetDocumentVersion (const Standard_Integer DocVersion)* and *static Standard_Integer DocumentVersion()* have been removed from *BinMDataStd*, *BinMNaming*, *XmlMDataStd* and *XmlMNaming*.

-@subsection upgrade_740_changed_api_of_brepmesh BRepMesh - revision of the data model
-
-The entire structure of *BRepMesh* component has been revised and separated into several logically connected classes.
-
-In new version, deflection is controlled more accurately, this may be necessary to tune parameters of call of the BRepMesh algorithm on the application side to obtain the same quality of presentation and/or performance as before.
-
-*BRepMesh_FastDiscret* and *BRepMesh_FastDiscretFace* classes have been removed.
-
-The following changes have been introduced in the API of *BRepMesh_IncrementalMesh*, component entry point:
-* Due to revised logic, *adaptiveMin* parameter of the constructor has been removed as meaningless;
-* *BRepMesh_FastDiscret::Parameters* has been moved to a separate structure called *IMeshTools_Parameters*; the signatures of related methods have been changed correspondingly.

-
-Some public methods of the class BRepFilletAPI_MakeChamfer are released from excess arguments:
-- method Add for symmetric chamfer now takes only 2 arguments: distance and edge;
-- method GetDistAngle now takes only 3 arguments: index of contour, distance and angle.
-
-@subsection upgrade_740_aspects Aspects unification
-
-Fill Area, Line and Marker aspects (classes *Graphic3d_AspectFillArea3d*, *Graphic3d_AspectLine3d*, *Graphic3d_AspectMarker3d* and *Graphic3d_AspectText3d*)
-have been merged into new class *Graphic3d_Aspects* providing a single state for rendering primitives of any type.
-The old per-primitive type aspect classes have been preserved as sub-classes of *Graphic3d_Aspects* with default values close to the previous behavior.
-All aspects except Graphic3d_AspectFillArea3d define Graphic3d_TOSM_UNLIT shading model.
-
-The previous approach with dedicated aspects per primitive type was handy in simplified case, but lead to confusion otherwise.
-In fact, drawing points or lines with lighting applied is a valid use case, but only *Graphic3d_AspectFillArea3d* previously defined necessary material properties.
-
-As aspects for different primitive types have been merged, Graphic3d_Group does no more provide per-type aspect properties.
-Existing code relying on old behavior and putting interleaved per-type aspects into single Graphic3d_Group should be updated.
-For example, the following pseudo-code will not work anymore, because all *SetGroupPrimitivesAspect* calls will setup the same property:
-~~~~
-Handle(Graphic3d_Group) aGroup = thePrs->NewGroup();
-aGroup->SetGroupPrimitivesAspect (myDrawer->ShadingAspect()->Aspect());
-aGroup->SetGroupPrimitivesAspect (myDrawer->LineAspect()->Aspect());    //!< overrides previous aspect
-
-Handle(Graphic3d_ArrayOfSegments) aLines = new Graphic3d_ArrayOfSegments (2);
-Handle(Graphic3d_ArrayOfTriangles) aTris = new Graphic3d_ArrayOfTriangles (3);
-aGroup->AddPrimitiveArray (aLines); //!< both arrays will use the same aspect
-aGroup->AddPrimitiveArray (aTris);
-~~~~
-
-To solve the problem, the code should be modified to either put primitives into dedicated groups (preferred approach), or using *SetPrimitivesAspect* in proper order:
-~~~~
-Handle(Graphic3d_Group) aGroup = thePrs->NewGroup();
-
-aGroup->SetGroupPrimitivesAspect (myDrawer->ShadingAspect()->Aspect());
-Handle(Graphic3d_ArrayOfTriangles) aTris = new Graphic3d_ArrayOfTriangles (3);
-aGroup->AddPrimitiveArray (aTris);
-
-Handle(Graphic3d_ArrayOfSegments) aLines = new Graphic3d_ArrayOfSegments (2);
-aGroup->SetPrimitivesAspect (myDrawer->LineAspect()->Aspect()); //!< next array will use the new aspect
-aGroup->AddPrimitiveArray (aLines);
-~~~~
-
-@subsection upgrade_740_materials Material definition
-
-Decomposition of Ambient, Diffuse, Specular and Emissive properties has been eliminated within *Graphic3d_MaterialAspect* definition.
-As result, the following methods of *Graphic3d_MaterialAspect* class have been removed: SetReflectionMode(), SetReflectionModeOn(), Ambient(), Diffuse(), Emissive(), Specular(), SetAmbient(), SetDiffuse(), SetSpecular(), SetEmissive().
-
-Previously, computation of final value required the following code:
-~~~~
-Graphic3d_MaterialAspect theMaterial; Quantity_Color theInteriorColor;
-Graphic3d_Vec3 anAmbient (0.0f);
-if (theMaterial.ReflectionMode (Graphic3d_TOR_AMBIENT))
-{
-  anAmbient = theMaterial.MaterialType (Graphic3d_MATERIAL_ASPECT)
-            ? (Graphic3d_Vec3 )theInteriorColor           * theMaterial.Ambient()
-            : (Graphic3d_Vec3 )theMaterial.AmbientColor() * theMaterial.Ambient();
-}
-~~~~
-
-New code looks like this:
-~~~~
-Graphic3d_MaterialAspect theMaterial; Quantity_Color theInteriorColor;
-Graphic3d_Vec3 anAmbient = theMaterial.AmbientColor();
-if (theMaterial.MaterialType (Graphic3d_MATERIAL_ASPECT)) { anAmbient *= (Graphic3d_Vec3 )theInteriorColor; }
-~~~~
-
-Existing code should be updated to:
-- Replace Graphic3d_MaterialAspect::SetReflectionModeOff() with setting black color; SetReflectionModeOn() calls can be simply removed.
-  R.g. theMaterial.SetAmbientColor(Quantity_NOC_BLACK).
-- Replace Graphic3d_MaterialAspect::Ambient(), SetAmbient(), Diffuse(), SetDiffuse(), Specular(), SetSpecular(), Emissive(), SetEmissive() with methods working with pre-multiplied color.
-  E.g. theMaterial.SetAmbientColor(Graphic3d_Vec3 (1.0f, 0.0f, 0.0f) * 0.2f).
-- Avoid using Graphic3d_MaterialAspect::Color() and SetColor() with non-physical materials (Graphic3d_MATERIAL_ASPECT).
-  These materials do not include color definition, because it is taken from Graphic3d_Aspects::InteriorColor() - this has not been changed.
-  However, previously it was possible storing the color with SetColor() call and then fetching it with Color() by application code (the rendering ignored this value);
-  now SetColor() explicitly ignores call for Graphic3d_MATERIAL_ASPECT materials and Color() returns DiffuseColor() multiplication coefficients.
-
-@subsection upgrade_740_text Changes in Graphic3d_Text and OpenGl_Text API
-
-Parameters of *Text* in *Graphic3d_Group* are moved into a new *Graphic3d_Text* class. *AddText* of *Graphic3d_Group* should be used instead of the previous *Text*.
-
-The previous code:
-~~~~
-Standard_Real x, y, z;
-theAttachmentPoint.Coord(x,y,z);
-theGroup->Text (theText,
-                Graphic3d_Vertex(x,y,z),
-                theAspect->Height(),
-                theAspect->Angle(),
-                theAspect->Orientation(),
-                theAspect->HorizontalJustification(),
-                theAspect->VerticalJustification());
-~~~~
-should be replaced by the new code:
-~~~~
-Handle(Graphic3d_Text) aText = new Graphic3d_Text (theAspect->Height());
-aText->SetText (theText.ToExtString());
-aText->SetPosition (theAttachmentPoint);
-aText->SetHorizontalAlignment (theAspect->HorizontalJustification());
-aText->SetVerticalAlignment (theAspect->VerticalJustification());
-theGroup->AddText (aText);
-~~~~
-
-*OpenGl_Text* contains *Graphic3d_Text* field.
-
-*OpenGl_TextParam* struct is removed. Constructor and *Init* of *OpenGl_Text* with *OpenGl_TextParam* are also removed.
-Instead of using them, change *OpenGl_Text*.
-
-Please, note, that after modifying *OpenGl_Text*, *Reset* of *OpenGl_Text* should be called.
-
-*FormatParams* of *OpenGl_Text* is replaced by *Text*.
-
-@subsection upgrade_740_prsupdate Presentation invalidation
-
-Historically AIS_InteractiveObject provided two independent mechanisms invalidating presentation (asking presentation manager to recompute specific display mode or all modes):
-
-1. *AIS_InteractiveObject::SetToUpdate()*, marking existing presentation for update.
-   This is main invalidation API, which is expected to be followed by *AIS_InteractiveContext::Update()* call.
-2. *AIS_InteractiveObject::myToRecomputeModes* + *myRecomputeEveryPrs*.
-   This is auxiliary invalidation API, used internally by AIS_InteractiveContext::SetColor()/UnsetColor() and similar modification methods.
-
-The latter one has been removed to avoid confusion and unexpected behavior.
-In addition, two methods *AIS_InteractiveObject::Update()* have been deprecated in favor of new *AIS_InteractiveObject::UpdatePresentations()* recomputing only invalidated presentations.
-
-Custom presentations implementing interface methods *AIS_InteractiveObject::SetColor()* and others should be revised to use *AIS_InteractiveObject::SetToUpdate()*
-or updating presentation without recomputation (see *AIS_InteractiveObject::SynchronizeAspects()* and *AIS_InteractiveObject::replaceAspects()*).
-
-@subsection upgrade_740_interiorstyles Interior styles

-  Specify Graphic3d_AspectFillArea3d::SetDrawEdges(true) with Graphic3d_AspectFillArea3d::SetInteriorStyle(Aspect_IS_EMPTY) to get previous behavior of Aspect_IS_HOLLOW style.
-* *Aspect_IS_HIDDENLINE* does not implicitly enables drawing mesh edges anymore.
-  Specify Graphic3d_AspectFillArea3d::SetDrawEdges(true) with Graphic3d_AspectFillArea3d::SetInteriorStyle(Aspect_IS_HIDDENLINE) to get previous behavior of Aspect_IS_HIDDENLINE style.

-@subsection upgrade_740_modedprs PrsMgr and SelectMgr hierarchy clean up
-
-Proxy classes *Prs3d_Presentation*, *PrsMgr_ModedPresentation* and *PrsMgr_Prs* have been removed.
-Code iterating through the list of low-level structures AIS_InteractiveObject::Presentations() should be updated to access PrsMgr_Presentation directly.
-Forward declarations of *Prs3d_Presentation* should be corrected, since it is now a typedef to *Graphic3d_Structure*.
-
-Proxy classes *SelectBasics_SensitiveEntity* and *SelectBasics_EntityOwner* have been removed - *Select3D_SensitiveEntity* and *SelectMgr_EntityOwner* should be now used directly instead.
-
-@subsection upgrade_740_offset Polygon offset defaults
-
-*Graphic3d_PolygonOffset* default constructor has been corrected to define Units=1 instead of Units=0.
-Default polygon offset settings Mode=Aspect_POM_Fill + Factor=1 + Units=1 are intended to push triangulation
-(Shaded presentation) a little bit behind of lines (Wireframe and Face Edges)
-for reducing z-fighting effect of Shaded+Wireframe combination.
-The change in defaults (Units changed from 0 to 1) is intended to cover scenario when camera direction is perpendicular to model plane (like 2D view).
-
-Application observing unexpected visual difference on this change should consider customizing this property within AIS_InteractiveContext default attributes
-or on per-presentation basis via *Graphic3d_Aspects::SetPolygonOffset()* methods.
-
-@subsection upgrade_740_zlayer Adding ZLayers in given position
-
-Interface of insertion ZLayer in the viewer has been improved with ability to insert new layer before or after existing one.
-Previously undocumented behavior of *V3d_Viewer::AddZlayer()* method has been corrected to insert new layer before *Graphic3d_ZLayerId_Top*.
-Applications might need revising their custom layers creation code and specify precisely their order with new methods *V3d_Viewer::InsertLayerBefore()* and *V3d_Viewer::InsertLayerAfter()*.
-

-| Font_FontAspect |
-
-@subsection upgrade_740_geproj Custom defines within env.bat
-
-*env.bat* produced by Visual Studio project generator *genproj.bat* has been modified so that *%CSF_DEFINES%* variable is reset to initial state.
-Custom building environment relying on old behavior and setting extra macros within *%CSF_DEFINES%* before env.bat should be updated
-to either modify custom.bat or setup new variable *%CSF_DEFINES_EXTRA%* instead.
-
-@subsection upgrade_740_BVH_in_BOP Switching Boolean Operations algorithm to use BVH tree instead of UB tree
-
-Since OCCT 7.4.0 Boolean Operations algorithm uses BVH tree instead of UBTree to find the pairs of entities with interfering bounding boxes.
-The following API changes have been made:
-* BOPTools_BoxBndTree and BOPTools_BoxBndTreeSelector have been removed. Use the BOPTools_BoxTree and BOPTools_BoxTreeSelector instead.
-* BOPTools_BoxSelector::SetBox() method now accepts the BVH_Box instead of Bnd_Box.
-* Methods BOPTools_BoxSelector::Reject and BOPTools_BoxSelector::Accept have been removed as unused.
-* The RunParallel flag has been removed from the list of parameters of BOPAlgo_Tools::IntersectVertices method. Earlier, it performed selection from the UB tree in parallel mode. Now all interfering pairs are found in one pass, using pair traverse of the same BVH tree.
-
-@subsection upgrade_740_stdnamespace Standard_Stream.hxx no more has "using std::" statements
-*Standard_Stream.hxx* header, commonly included by other OCCT header files, does no more add entities from *std namespace* related to streams (like *std::cout*, *std::istream* and others) into global namespace.
-The application code relying on this matter should be updated to either specify std namespace explicitly (like std::cout) or add "using std::" statements locally.

-@section upgrade_occt750 Upgrade to OCCT 7.5.0
-
-@subsection upgrade_750_srgb_color RGB color definition
-
-OCCT 3D Viewer has been improved to properly perform lighting using in linear RGB color space and then convert result into non-linear gamma-shifted sRGB color space before displaying on display.
-This change affects texture mapping, material definition and color definition.
-
-Previously *Quantity_Color* definition was provided with unspecified RGB color space.
-In practice, mixed color spaces have been actually used, with non-linear sRGB prevailing in general.
-Since OCCT 7.5.0, *Quantity_Color* now specifies that components are defined in linear RGB color space.
-
-This change affects following parts:
-* Standard colors defined by *Quantity_NameOfColor* enumeration have been converted into linear RGB values within Quantity_Color construction.
-* Application may use new enumeration value *Quantity_TOC_sRGB* for passing/fetching colors in sRGB color space,
-  which can be useful for interoperation with color picking widgets (returning 8-bit integer values within [0..255] range)
-  or for porting colors constants within old application code without manual conversion.
-* *Graphic3d_MaterialAspect* color components are now expected in linear RGB color space,
-  and standard OCCT materials within *Graphic3d_NameOfMaterial* enumeration have been updated accordingly.
-* Texture mapping now handles new *Graphic3d_TextureRoot::IsColorMap()* for interpreting content in linear RGB or sRGB color space.
-  It is responsibility of user specifying this flag correctly. The flag value is TRUE by default.
-* Method *Image_PixMap::PixelColor()* has been extended with a new Boolean flag for performing linearization of non-linear sRGB.
-  This flag is FALSE by default; application should consider passing TRUE instead for further handling *Quantity_Color* properly as linear RGB values.
-

-* *Prs3d::GetDeflection()* has been moved to *StdPrs_ToolTriangulatedShape::GetDeflection()*.
-* *Prs3d_ShapeTool* has been moved to *StdPrs_ShapeTool*.
-* *StdSelect_ViewerSelector3d* has been moved to *SelectMgr_ViewerSelector3d*.
-* *Font_BRepFont* has been moved to *StdPrs_BRepFont*.
-* Visualization classes now use *TopLoc_Datum3D* (from *TKMath*) instead of *Geom_Transformation* (from *TKG3d*) as smart pointer to *gp_Trsf*.
-  This is rather an internal change, but some applications might need to be updated.
-
-@subsection upgrade_750_hlrangle Prs3d_Drawer deviation angle
-
-Properties Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::HLRDeviationCoefficient() have been removed from classes *Prs3d_Drawer*, *AIS_Shape* and *AIS_InteractiveContext*.
-Prs3d_Drawer::DeviationAngle() should be now used instead of Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::DeviationCoefficient() instead of Prs3d_Drawer::HLRDeviationCoefficient().
-The default value of Prs3d_Drawer::DeviationAngle() property has been changed from 12 to 20 degrees to match removed Prs3d_Drawer::HLRAngle(), previously used as input for triangulation algorithm.

-@subsection upgrade_750_Adaptor2d_OffsetCurve  Offset direction change
-
-Offset direction, which used in class Adaptor2d_OffsetCurve for evaluating values and derivatives of offset curve is unified for offset direction used in class Geom2d_OffsetCurve: now offset direction points to outer ("right") side of base curve instead of the previously used inner ("left") side. Old usage of class in any application should be changed something like that:
-
-Adaptor2d_OffsetCurve aOC(BaseCurve, Offset) --> Adaptor2d_OffsetCurve aOC(BaseCurve, -Offset)

-@subsection upgrade_750_message_messenger Message_Messenger interface change
-
-Operators << with left argument *Handle(Message_Messenger)*, used to output messages with
-a stream-like interface,  have been removed.
-This functionality is provided now by separate class *Message_Messenger::StreamBuffer*.
-That class contains a stringstream buffer which can be filled using standard stream
-operators. The string is sent to a messenger on destruction of the buffer object,
-call of its method Flush(), or using operator << with one of ostream manipulators 
-(*std::endl, std::flush, std::ends*). Manipulator *Message_EndLine* has been removed,
-*std::endl* should be used instead.
-
-New methods *SendFail(), SendAlarm(), SendWarning(), SendInfo()*, and *SendTrace()* are
-provided in both *Message_Messenger* class and as static functions in *Message* package
-(short-cuts to default messenger), returning buffer object for the output of
-corresponding type of the message.
-
-The code that used operator << for messenger, should be ported as follows.
-
-Before the change:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  theMessenger << "Value = " << anInteger << Message_EndLine;
-~~~~~
-
-After the change, single-line variant:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  theMessenger->SendInfo() << "Value = " << anInteger << std::endl;
-~~~~~
-
-After the change, extended variant:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  Message_Messenger::StreamBuffer aSender = theMessenger->SendInfo();
-  aSender << "Array: [ ";
-  for (int i = 0; i < aNb; ++i) { aSender << anArray[i] << " "; }
-  aSender << "]" << std::endl; // aSender can be used further for other messages
-~~~~~

-@subsection upgrade_750_message_printer Message_Printer interface change
-
-Previously, sub-classes of *Message_Printer* have to provide a triplet of *Message_Printer::Send()* methods accepting different string representations: TCollection_AsciiString, TCollection_ExtendedString and Standard_CString.
-*Message_Printer* interface has been changed, so that sub-classes now have to implement only single method *Message_Printer::send()* accepting TCollection_AsciiString argument and having no Endl flag, which has been removed.
-Old three Message_Printer::Send() methods remain defined virtual with unused last argument and redirecting to new send() method by default.

-# Preface
-
-**Empirical** illumination models like **Phong reflection model** have been used in real-time graphics for a long time due to their simplicity, convincing look and affordable performance.
-Before programmable pipeline has been introduced, graphics cards implemented Gouraud shading as part of fixed-function Transformation & Lighting (T&L) hardware blocks.
-Nowadays, however, numerous trade-offs of this simplicity (like lighting partially baked into object material properties and others) pushed developers to **Physically-Based Rendering** (**PBR**) illumination models.
-
-PBR models try to fit surface shading formulas into constrains of physical laws of light propagation / absorption / reflection - hence, called "physically-based".
-There are two main categories of PBR illumination:
-
- 1. Non-real-time renderer (cinematic).
- 2. Real-time renderer.
-
-The main objective of cinematic renderer is uncompromised quality, so that it relies on ray-tracing (path-tracing) rendering pipeline.
-Although performance of current graphics hardware does not make it possible using computationally-intensive path-tracing renderer in real-time graphics, it can be used in interactive fashion.
-
-"Physically-based" does not necessarily mean physically-correct/precise.
-The main objective of real-time PBR renderer is to be fast enough even on low-end graphics hardware.
-So that in contrast, it hardly relies on rasterization rendering pipeline, various approximations and tricks making it applicable in real-time, while looking good enough and preserving some physical properties.
-
-OCCT 3D Viewer provides both kinds of PBR renderers, and although they share some details in common, this article is devoted to real-time PBR metallic-roughness illumination model.
-This article describes the math underneath PBR shading in OCCT 3D Viewer and its GLSL programs.
-However, this article does not clarifies related high-level APIs nor PBR material creation pipelines, as this is another topic.

-# Illumination model
-
-The main goal of illumination model is to calculate outgoing light radiance \f$L_o\f$ along the certain direction.
-The starting point of calculation might be the view direction \f$v\f$ aimed from point on surface (or in more general case just in space) to viewer position.
-Considering the point on opaque surface with normal \f$n\f$ the main equation of illumination can be defined as:
-
-\f[L_o=\int\limits_H f(v, l) L_i(l) \cos\theta_l\, \mathrm{d}l\f]
-
-Where \f$L_i(l)\f$ is light radiance coming from \f$l\f$ direction, \f$f(v,l)\f$ is **Bidirectional Reflectance Distribution Function** (**BRDF**) and \f$H\f$ is hemisphere which is oriented regarding to the surface normal \f$n\f$.
-Opaqueness of the surface mentioned earlier is important because in that case hemisphere is enough.
-More general model will require to consider directions all around a whole sphere and is not observed in this paper.
-\f$\cos\theta_l\f$ factor appearing is caused by affection of surface area and light direction mutual orientation to the amount of radiance coming to this area.
-This is mainly due to geometric laws. The rest part of integral is the key of the whole illumination model.
-BRDF defines it's complexity and optical properties of material.
-It has to model all light and material interactions and also has to satisfy some following criteria in order to be physical correct:
-* Positivity: \f$f(v,l) \geq 0\f$
-* Helmholtz reciprocity: \f$f(v,l) = f(l, v)\f$ (follows from 2<sup>nd</sup> Law of Thermodynamics)
-* Energy conservation: \f$\displaystyle \forall v \, \int\limits_H f(v,l) \cos\theta_l \, \mathrm{d}l = 1\f$ (in order not to reflect more light than came)
-
-It is worth to be mentioned that \f$f(v,l)\f$ depends on \f$n\f$ also but it is omitted to simplify notation. BRDF is usually split into two parts:
-
-\f[f(v,l) = f_d(v,l)+f_s(v, l)\f]
-
-Where \f$f_s(v, l)\f$ (specular BRDF) models reflection light interaction on surface and \f$f_d(v,l)\f$ (diffuse BRDF) models other processes happening depth in material (subsurface scattering for example).
-So that illumination equation might be rewritten as:
-
-\f[L_o=\int\limits_H (f_d(v,l)+f_s(v, l)) L_i(l) \cos\theta_l\, \mathrm{d}l\f]
-
-PBR theory is based on **Cook-Torrance specular BRDF**. It imagines surface as set of perfectly reflected micro faces distributed on area in different ways which is pretty good model approximation of real world materials.
-If this area is small enough not to be able to recognize separate micro surfaces the results becomes a sort of averaging or mixing of every micro plane illumination contribution.
-In that level it allows to work with micro faces in statistical manner manipulating only probabilities distributions of micro surfaces parameters such as normals, height, pattern, orientation etc.
-In computer graphics pixels are units of images and it usually covers a relatively large areas of surfaces so that micro planes can be considered to be unrecognizable.
-Going back to the BRDF the Cook-Torrance approach has the following expression:
-
-\f[f_s(v,l)=\frac{DGF}{4\cos\theta_l\cos\theta_v}\f]
-
-Three parts presented in nominator have its own meaning but can have different implementation with various levels of complexity and physical accuracy.
-In that paper only one certain implementation is used. The \f$D\f$ component is responsible for **micro faces normals distribution**.
-It is the main instrument that controls reflection's shape and strength according to **roughness** \f$r\f$ parameter.
-The implementation with good visual results is **Trowbridge-Reitz GGX** approach used in Disney's RenderMan and Unreal Engine:
-
-\f[D=\frac{\alpha^2}{\pi(\cos^2\theta_h(\alpha^2-1) + 1)^2}\f]
-
-Where \f$\alpha = r^2\f$. This square in needed only for smoother roughness parameter control.
-Without it the visual appearance of surface becomes rough too quickly during the parameter's increasing.
-
-The second \f$G\f$ component is called **geometric shadowing** or attenuation factor.
-The point is that micro surfaces form kind of terrain and can cast shadows over each other especially on extreme viewing angles.
-**Schlick's model** has been chosen as implementation:
-
-\f[\displaystyle G=\frac{\cos\theta_l \cos\theta_v}{(\cos\theta_l(1-k)+k)(\cos\theta_v(1-k)+k)}\f]
-
-Where \f$k=\frac{\alpha}{2}\f$, which means \f$k=\frac{r^2}{2}\f$ in terms of this paper.
-But \f$G\f$ depends on many factors so that it's approximations has float nature and can be modified a little bit in some cases in order to get more pleasant visual results.
-One of this modification will be described later in following chapters.
-
-The last component \f$F\f$ shows **how much light is reflected from surface** and is called **Fresnel's factor**.
-The rest amount of radiance might be absorbed or refracted by material.
-The most accurate expression of it is pretty complicate for calculation so that there is a variety of approximations.
-The good one with less computation efforts is **Schlick's implementation**:
-
-\f[F=F_0+(1-F_0)(1-\cos\theta_{vh})^5\f]
-
-Here \f$F_0\f$ is material's response coefficient at normal incidence (zero angle).
-Fresnel's factor has to be calculated differently for metals and dielectric/non-metals, but PBR theory tries to come up with universal formula for all types of material.
-In order to do that it is needed to be noticed that Schlick's approximation is applicable only to non-conductors and in that case \f$F_0 = F_{dielectric} = \left(\frac{1-IOR}{1+IOR}\right)^2\f$.
-**Index of Refraction** \f$IOR\f$ shows the proportion between light speed in vacuum (or even in air) and in material.
-The reference value of \f$IOR\f$ for plastic is **1.5**, and this value can be considered as default for all unknown dielectrics.
-In practice this parameter controls reflectance ability of material.
-Also it should be remembered that this approximation produces poor results with large \f$IOR\f$ values so that it is recommended to be kept in range of \f$[1, 3]\f$ in order to get plausible Fresnel's factor.
-This formula might be further propagated onto metals by using \f$F_0\f$ measured specifically for certain metal.
-It can be considered as some kind of a 'color' of metal and can be stored as albedo parameter \f$c\f$.
-And the final step of defining Fresnel's factor formula is mixing all this \f$F_0\f$ using metallic parameter \f$m\f$ (**metalness**):
-
-\f[F_0 = F_{dielectric}(1-m)+cm\f]
-
-For pure dielectrics with \f$m=0\f$ exactly Schlick's approximation will be used.
-For pure metals with \f$m=1\f$ it will be a little inaccurate but the same formula with measured \f$F_0\f$ values.
-Everything else for \f$m \in (0, 1)\f$ is not physically correct and it is recommended to keep \f$m\f$ exactly 1 or 0.
-Intermediate values may represent mixed areas for smooth transition between materials - like partially rusted metal (rust is mostly dielectric).
-Also it might be useful when parameters are read from textures with filtering and smoothing.
-
-BRDF described above has one important trait making computations easier called **isotropy**.
-Isotropy in this case means independence from rotation about normal resulting from supposition of uniform micro faces distribution at any direction along a surface.
-It allows to simplify random samples generation during Monte-Carlo integrals calculation and reduce dimensions of some lookup tables, which will be discussed in following chapters.
-Of course, isotropic materials form only subset of all real world's materials, but this subset covers majority of cases.
-There are special models considering special anisotropic traits of surfaces like a grinding of metal or other with dependency on rotation about normal;
-these models require special calculation tricks and additional parameters and are out of scope of this paper.
-
-The only thing left to do is to define \f$f_d(v,l)\f$.
-This part is responsible for processes happening in depth of material.
-First of all the amount of input light radiance participating in these processes is needed to be calculated.
-And it exactly can be realized from already known Fresnel's factor \f$F\f$ showing amount of reflected light but in negative term in this case in order to get the radiance left after reflection:
-
-\f[1-F\f]
-
-This part of ingoing light is assumed to be refracted in depth of surface and variety of events may happen there.
-A sequence of absorptions, reflections and reemissions more or less leads to light's subsurface scattering.
-Some part of this scattered light can go back outside but in modified form and in pretty unpredictable directions and positions.
-For opaque materials this part is noticeable and forms it's own color.
-If subsurface's paths of light are small enough and points of output are distributed locally around the input point it's possible to work in statistical way similar to the micro faces.
-This assumption covers a big amount of real world opaque materials.
-Other materials like skin, milk etc. with noticeable effect of subsurface scattering usually presented in form of partial translucency and some kind of self emission
-have more widely distributed output points and require more accurate and complicate ways of modeling with maybe some theory and techniques from volumetric rendering.
-The simple but visually enough assuming for statistically driven type of materials is just the same radiance for any direction. It results to **Lambertian's BRDF**:
-
-\f[\frac{c}{\pi}\f]
-
-Where \f$\pi\f$ is normalization coefficient in order to meet BRDF's criteria and \f$c\f$ is material's own color formed by adventures of light under surface.
-There is one detail about light interaction bringing some physicality to the model, and that is an absence of this diffuse component in metals.
-Metals reflect main part of light and the rest of it is absorbed being transformed into other form (mostly heat).
-That is the main visual difference between metallic and non-metallic materials realizing of which brings model to higher level of quality in compare to older non-physical models.
-
-So that all parts described above can be combined into united diffuse BRDF:
-
-\f[f_d(v,l) = (1-F)(1-m)\frac{c}{\pi}\f]
-
-\f$m\f$ is recommended to be exactly 1 or 0 but all values between can represent transition areas, as mentioned before.
-
-In this chapter one possible implementation of illumination model reflecting main PBR principles has been defined.
-The next step is using of it in practice.
-
-# Practical application
-
-It's time to apply deduced illumination model in practice.
-And the first step of it is separation of **direction based light sources** from illumination integral.
-Directional nature of such light sources means possibility to calculate it's influence to point of surface using only one direction and its intensity.
-Usually sources of this type do not have physical size and are represented only by position in space (for point or spot lights) or by direction itself (direction light imagined to be too far point sources like sun).
-This is just a kind of abstraction, while real world light emitters have noticeably sizes.
-But sources with realistic form and size cannot be presented in discrete term and require continuous integrals calculations or special approximations in order to be accurately injected to the model.
-In most cases direct based light sources in form of emitting points in space or just certain directions are good approximations and are enough for beginning.
-Having finite discrete amount of it in scene and considering only single direction from every of these lights, the integral is transformed just to the sum:
-
-\f[L_{direct} = \sum_{j=1}^M f(v, l_j) L_i^{direct}(l_j) \cos\theta_{l_j}\f]
-
-Where \f$M\f$ is a number of sources, \f$l_j\f$ is a direction and \f$L_i^{direct}\f$ is an intensity related to this direction.
-\f$direct\f$ label means that illumination has been computed directly from sources.
-The BRDF can be used directly without any calculation problems.
-The only exception might be \f$k\f$ in \f$G\f$ factor - it is recommended to be equal \f$\frac{(r+1)^2}{8}\f$ in order to get more pleasant results (that is modification mentioned in previous chapter).
-And actually it is enough to finally see something.
-There will be correct visualization with assumption of complete dark environment and absence of other points influence.
-It is called **local illumination**. Based on this name there is also a global or **indirect illumination** and that is the rest of integral:
-
-\f[L_{indirect} = \int\limits_H f(v, l) L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-It includes influence of light reflected or scattered from other points and environment's contribution.
-It's impossible to achieve photorealistic results without this component, but is is also very difficult to compute.
-While the cross point light interaction cannot be calculated in a simple way (especially in real time rendering), the environment illumination has some options to be realized via precomputational work before visualization.
-But right now lets summarize the practical application of illumination model.
-At this moment the output radiance is represented as:
-
-\f[L_o = L_{direct} + L_{indirect}\f]
-
-Where \f$L_{direct}\f$ is direction based light sources contribution which can be directly computed just applying bare formulas.
-It is enough to get some results in terms of local illumination but without \f$L_{indirect}\f$ component image will not be looked lifelike.
-\f$L_{indirect}\f$ is not trivial thing for calculation and that is stumbling block for real time rendering applications.
-But it can be relatively easy implemented in case of environment illumination via some precomputational work about which will be told in details in following chapters.
-
-# Image based lighting
-
-The next goal after \f$L_{direct}\f$ calculation is to find \f$L_{indirect}\f$.
-And it would be easier if \f$L_i^{indirect}(l)\f$ was known for every \f$l\f$.
-That is the main assumption of **image based lightning** (**IBL**).
-In practice, it can be achieved using environment image map, which is a special image representing illumination from all possible directions.
-This image might be a photo capturing a real world environment (spherical 360 degrees panoramas) or generated image baking the 3D scene itself, including in that case reflections of other objects.
-Environment image might be packed in different ways - **cube maps** and equirectangular maps are the most commonly used.
-Anyway, it allows \f$L_i^{indirect}(l)\f$ to be defined for every \f$l\f$ and its practical implementation in form of images gives name for this approach.
-Lets back to indirect illumination integral:
-
-\f[L_{indirect} = \int\limits_H f(v, l) L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-Substituting the BRDF by its expression allows to split indirect illumination into diffuse and specular components:
-
-\f[L_{indirect} = \int\limits_H f_d(v,l)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l + \int\limits_H f_s(v,l)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l = \f]
-
-\f[= (1-m)\frac{c}{\pi}\int\limits_H (1-F)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l + \frac{1}{4}\int\limits_H \frac{DFG}{\cos\theta_l \cos\theta_v}L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l\f]
-
-This splitting seems not to lead to simplicity of calculation but these two parts will be computed in slightly different ways in future.
-Lets write down this separately:
-
-\f[L_{indirect}^d = (1-m)\frac{c}{\pi}\int\limits_H (1-F)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l\f]
-
-\f[L_{indirect}^s = \frac{1}{4}\int\limits_H \frac{DFG}{\cos\theta_v \cos\theta_l} L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-Next transformations of these expressions require understanding of numerical way to find hemisphere integral and also its performance optimization techniques.
-And that the topic of the next chapter.
-
-# Monte-Carlo numeric integration
-
-**Monte-Carlo** is one of numeric methods to **find integral**.
-It is based on idea of mathematical expectation calculation.
-In one dimensional case if \f$f(x)\f$ is a function with parameter distributed according to probability density \f$p(x)\f$ the mathematical expectation of it can be found using following expression:
-
-\f[E = \int\limits_{-\infty}^\infty f(x) p(x)\, \mathrm{d}x\f]
-
-Also this expectation can be approximated in statistical term using certain sequence of random variable \f$x\f$:
-
-\f[E \approx \frac{1}{N} \sum_{i=1}^{N} f(x_i)\f]
-
-It can be used in general definite integrals calculations.
-Just valid \f$p(x)\f$ defined on \f$[a, b]\f$ range and sequence \f$x_i\f$ generated according to it are needed for that:
-
-\f[\int\limits_a^b f(x)\, \mathrm{d}x = \int\limits_a^b \frac{f(x)}{p(x)}p(x)\, \mathrm{d}x = \int\limits_{-\infty}^{\infty} \frac{f(x)}{p(x)}p(x)\, \mathrm{d}x \approx \frac{1}{N} \sum_{i=1}^{N} \frac{f(x_i)}{p(x_i)}\f]
-
-Where \f$f(x)\f$ is considered to be equal to zero outside of \f$[a, b]\f$ range.
-This is also true for functions on sphere or hemisphere:
-
-\f[\int\limits_{H|S} f(l)\, \mathrm{d}l \approx \frac{1}{N}\sum_{i=1}^{N} \frac{f(l_i)}{p(l_i)}\f]
-
-The main questions are choosing \f$p(l)\f$ and generating samples \f$l_i\f$.
-The one of the simple ways is uniform distribution along sphere or hemisphere.
-Lets realize that on sphere for example.
-There are \f$4\pi\f$ possible directions in terms of sphere's areas and steradians (direction can be presented as dot on a unit sphere):
-
-\f[\int\limits_S 1\, \mathrm{d}l = 4\pi\f]
-
-Where \f$S\f$ is the unit sphere.
-In order to be uniform \f$p(l)\f$ must be constant and satisfy normalization criteria:
-
-\f[\int\limits_S p(l)\, \mathrm{d}l = 1\f]
-
-So that \f$p(l) = \frac{1}{4\pi}\f$.
-Usually direction \f$l\f$ is parametrized by spherical coordinates \f$\phi \in [0, 2\pi]\f$ and \f$\theta \in [0, \pi]\f$ boiling down to the 2D samples generation.
-But in these terms joint \f$p(\theta, \phi)\f$ will be looked slightly different due to variables transition.
-\f$l\f$ is defined in regular Cartesian coordinates \f$l=(x, y, z)\f$ with \f$\|l\| = 1\f$.
-The spherical coordinates transform looks like:
-
-\f[x = r\sin\theta\cos\phi,\, y = r\sin\theta\sin\phi,\, z = r\cos\theta\f]
-
-Where \f$r = 1\f$.
-In order to express probability density using new variables it is needed to multiply this density by Jacobian of transform:
-
-\f[p(\theta,\phi) = p(l)|J_T|\f]
-
-Where:
-
-\f[|J_T| = \begin{vmatrix} \frac{\partial x}{\partial r} & \frac{\partial x}{\partial \theta} & \frac{\partial x}{\partial \phi} \\ \frac{\partial y}{\partial r} & \frac{\partial y}{\partial \theta} & \frac{\partial y}{\partial \phi} \\ \frac{\partial z}{\partial r} & \frac{\partial z}{\partial \theta} & \frac{\partial z}{\partial \phi} \end{vmatrix} = r^2\sin\theta\f]
-
-So that joint probability density in new variables looks like:
-
-\f[p(\theta, \phi) = \frac{\sin\theta}{4\pi}\f]
-
-This variable transfer rule of **Probability Density Function** (**PDF**) will be useful in following chapters, when integral calculation optimization techniques will be being told.
-Having \f$p(\theta, \phi)\f$ the partial single dimensional probability densities are able to be found:
-
-\f[p(\phi) = \int\limits_0^\pi p(\theta, \phi)\, \mathrm{d}\theta = \frac{1}{4\pi} \int\limits_0^\pi \sin\theta\, \mathrm{d}\theta = \frac{1}{2\pi}\f]
-
-\f[p(\theta) = \int\limits_0^{2\pi} p(\theta, \phi)\, \mathrm{d}\phi = \frac{\sin\theta}{4\pi}\int\limits_0^{2\pi}1\, \mathrm{d}\phi = \frac{\sin\theta}{2}\f]
-
-The final step is sequence generation itself.
-In order to be able to generate values with arbitrary distributions it is helpful to start from uniform numbers in range of \f$[0, 1]\f$.
-And that can be done via any known true- and pseudo- random generators.
-Even simple \f$\frac{1}{i}\f$ sequence is appropriate for beginning but it can be not so efficient in terms of computations convergence.
-There are specially designed series for the last reason and it will be tackled in chapter about optimizations.
-The \f$\phi\f$ variable is noticed to be uniformly distributed so that it can be directly generated without any additional manipulations.
-Just range \f$[0, 1]\f$ is needed to be mapped to range \f$[0, 2\pi]\f$.
-For any other variables including \f$\theta\f$ the inverse transform sampling approach can be applied.
-First of all **cumulative distribution function** (**CDF**) is needed to be found.
-It is probability of random value to be less than argument of this functions by definition.
-For continues distributions it can be expressed in following form:
-
-\f[F(x) = \int\limits_{-\infty}^x p(x')\, \mathrm{d}x'\f]
-
-Lets find CDF for \f$\theta\f$:
-
-\f[F(\theta) = \int\limits_{-\infty}^\theta p(\theta')\, \mathrm{d}\theta' = \int\limits_0^\theta \frac{\sin\theta'}{2}\, \mathrm{d}\theta' = \frac{1-\cos\theta}{2}\f]
-
-The CDF maps \f$\theta\f$ values from range of \f$[0, \pi]\f$ to probability in range of \f$[0, 1]\f$.
-The next step is to find inverse cumulative function which can be not so trivial sometimes but pretty obvious in current case:
-
-\f[F^{-1}(u) = \arccos(1-2u)\f]
-
-If substitute uniform distributed in range \f$[0, 1]\f$ values \f$u\f$ as argument of this function the values with origin probability density will appear.
-In other words:
-
-\f[\theta = \arccos(1 - 2u),\, u \in [0, 1],\, p(u) = 1 \Rightarrow p(\theta) = \frac{\sin\theta}{2}\f]
-
-That is the key of this random values generation technique.
-All steps described above can be also done for hemisphere:
-
-\f[p(l) = \frac{1}{2\pi}\f]
-
-\f[p(\theta, \phi) = \frac{\sin\theta}{2\pi}\f]
-
-\f[p(\phi) = \int\limits_0^\frac{\pi}{2} p(\theta, \phi)\, \mathrm{d}\theta = \frac{1}{2\pi} \int\limits_0^\frac{\pi}{2} \sin\theta\, \mathrm{d}\theta = \frac{1}{2\pi}\f]
-
-\f[p(\theta) = \int\limits_0^{2\pi} p(\theta, \phi)\, \mathrm{d}\phi = \frac{\sin\theta}{2\pi}\int\limits_0^{2\pi}1\, \mathrm{d}\phi = \sin\theta\f]
-
-\f[\theta = \arccos(1-u)\f]
-
-Mote-Carlo integration cannot guarantee exact estimation of convergence speed with using random generated samples.
-There is only probability estimation of it.
-But this algorithm is pretty universal and relatively simple to be applied to almost any function using at least uniform distributed points.
-Moreover special \f$p(l)\f$ can be chosen and special pseudo-random sequences can be designed in order to speed up convergence for some functions (following chapter talk about that in details).
-That is why this method is widely used in computer graphics and demonstrates good results.
-Also another one advantage is worth to be mentioned - possibility to iteratively accumulate computations and present intermediate results during rendering which is used in some ray tracing applications.
-
-# Split sum
-
-Lets go back to the image based lighting and the figure of specular component.
-As was defined before that is hemisphere integral with following expression:
-
-\f[L_{indirect}^s = \frac{1}{4}\int\limits_H \frac{DFG}{\cos\theta_v \cos\theta_l} L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-The Monte-Carlo integration algorithm can be directly applied:
-
-\f[L_{indirect}^s = \int\limits_H f_s(v, l)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l \approx \frac{1}{N}\sum_{i=1}^N \frac{f_s(v, l_i) L_i^{indirect}(l_i) \cos\theta_{l_i}}{p(v, l_i)}\f]
-
-\f$p(v, l_i)\f$ depends on \f$v\f$ and implicitly on \f$r\f$ in order to be completely general.
-Optimization strategies use different samples distributions for different view direction orientations and roughness values.
-Anyway even with all optimization techniques this algorithm continues to require too much calculations.
-Good visual results require noticeable number of samples and using this approach for every point in real time rendering becomes unrealistic.
-The way to avoid these enormous calculations is doing them beforehand somehow.
-The first trick on the way to this is split the sum separating environment light component:
-
-\f[L_{indirect}^s \approx \frac{1}{N} \sum_{i=1}^N \frac{f_s(v, l_i) L_i^{indirect}(l_i) \cos\theta_{l_i}}{p(v, l_i)} \approx \left( \frac{1}{N} \sum_{i=1}^N L_i^{indirect}(l_i) \right) \left( \frac{1}{N} \sum_{i=1}^N \frac{f_s(v, l_i) \cos\theta_{l_i}}{p(v, l_i)} \right)\f]
-
-Where the second brackets represent approximation of integral so that the expression can be rewritten as:
-
-\f[L_{indirect}^s \approx \frac{1}{N} \sum_{i=1}^N \frac{f_s(v, l_i) L_i^{indirect}(l_i) \cos\theta_{l_i}}{p(v, l_i)} \approx \left( \frac{1}{N} \sum_{i=1}^N L_i^{indirect}(l_i) \right) \int\limits_H f_s(v, l) \cos\theta_l\, \mathrm{d}l\f]
-
-This integral is exact \f$L_{indirect}^s\f$ in condition when \f$L_i^{indirect}(l) = 1\f$ what just means white uniform environment.
-The sum before it is kind of averaged environment illumination.
-The main accomplishment after all this manipulations is possibility to calculate light and BRDF components separately.
-The sum with \f$L_i^{indirect}(l_i)\f$ can be computed beforehand for every normal direction and stored to image called specular map but with some valuable details.
-The problem is that \f$l_i\f$ samples must be generated according to \f$p(v, l_i)\f$ distribution depended on \f$v\f$ and \f$r\f$ as was mentioned earlier.
-Variation of normal is not enough in that case and these variables are needed to be considered too.
-The ways to resolve it are topic of one of the following chapters and now understanding the fact that at least this part can be precomputed before rendering is enough for now.
-And it is important not to miss out that there is no more BRDF influence in this sum and only \f$p(v, l)\f$ can affect in this case.
-That is why it is so important to strict to PDF during samples generation and that is why \f$p(v, l)\f$ must be correlated with BRDF somehow in this approximation approach with splitting.
-For example completely mirroring materials with \f$r = 0\f$ will not be looked as expected if just uniform distribution is used
-because such surfaces have only one possible direction from which light can be reflected along view direction in compare with \f$N\f$ absolutely scattered in case of uniform or many other distributions.
-
-The rest part also can be saved to image. Lets unroll its expression:
-
-\f[\int\limits_H f_s(v, l) \cos\theta_l\, \mathrm{d}l = \int\limits_H \frac{DGF}{4\cos\theta_v \cos\theta_l} \cos\theta_l\, \mathrm{d}l\f]
-
-This integral is not actually a scalar.
-That is RGB value due to only \f$F\f$ factor and even more only to \f$F_0\f$.
-In order to simplify future computations \f$F_0\f$ is needed to be moved out of integral.
-Substitution of Schlick's approximation helps to achieve it:
-
-\f[F = F_0+(1-F_0)(1-\cos\theta_{vh})^5 = F_0(1-(1-\cos\theta_{vh})^5) + (1-\cos\theta_{vh})^5\f]
-
-\f[\int\limits_H \frac{DGF}{\cos\theta_v \cos\theta_l} \cos\theta_l\, \mathrm{d}l = F_0 \int\limits_H \frac{DG}{4\cos\theta_v \cos\theta_l} (1-(1-\cos\theta_{vh})^5) \cos\theta_l\, \mathrm{d}l + \int\limits_H \frac{DG}{4\cos\theta_v \cos\theta_l} (1-\cos\theta_{vh})^5 \cos\theta_l\, \mathrm{d}l\f]
-
-This form may not look easier, but it has several advantages.
-The first one is independence from globally defined \f$L_i^{indirect}(l)\f$, so that normal orientation does not matter and can be set in any handful way for calculations (Z axis for example).
-The second one results from isotropic illumination system allowing \f$\phi\f$ component of view vector to be set arbitrarily (0 for example) and \f$\cos\theta_v\f$ will be enough to define view direction.
-And the third one is scalar nature of integrals so that only two precomputed numbers are needed to find BRDF part of \f$L_{indirect}^s\f$.
-Considering dependency of these integrals from \f$\cos\theta_v\f$ and \f$r\f$ both of it can be precomputed and stored to 2D look-up image variating these two parameters in range \f$[0, 1]\f$ with two channels consisting of scale and bias for \f$F_0\f$.
-
-Current result for \f$L_{indirect}^s\f$ is computing it using 2D image for BRDF part and omnidirectional image for environment illumination.
-There were a lot of words about Monte-Carlo optimizations techniques and about PDF choice which is important not only in terms of numeric integration but in terms of visual results correctness.
-It's time to talk about that.
-
-# Importance sampling
-
-Current goal is to speed up Monte-Carlo integration of Cook-Torrance like integrals with following expression:
-
-\f[\int\limits_H \frac{DG}{4\cos\theta_v \cos\theta_l} g(v, l) \cos\theta_l\, \mathrm{d}l\f]
-
-Where \f$g(v, l)\f$ is just arbitrary function representing Fresnel's factor itself or its components.
-In order to increase convergence the samples with larger contribution (or in other words with larger function's values) have to appear more frequently than others proportionally to its contribution.
-So that less significant summand with less influence to result will be considered rarely and in opposite way parts brining noticeable changes to the sum will be taken often.
-That is the main idea of **importance sampling technique**.
-\f$p(l)\f$ has to represent significance of sample in terms of integrated function via probability somehow.
-And it will be like that if PDF is already part of original function because in that case probability density directly affects to contribution forming.
-Separating this distribution component is one possible and effective way to realize importance sampling strategy.
-In integral presented above PDF part already exists and that is \f$D\f$ component.
-But it is distribution of micro faces normals or ideally reflection direction or \f$h\f$ in other word and not light directions distribution which is needed in fact.
-Anyway that is good starting point and lets generate \f$h\f$ vectors first.
-\f$D\f$ has the following expression:
-
-\f[D=\frac{\alpha^2}{\pi(\cos^2\theta_h(\alpha^2-1) + 1)^2}\f]
-
-Frankly speaking \f$D(h)\f$ is called normal distribution but cannot be directly used as hemisphere distribution.
-Originally it is statistical factor used to define total area of micro faces \f$\mathrm{d}A_h\f$
-whose normals lie withing given infinitesimal solid angle \f$\mathrm{d}h\f$ centered on \f$h\f$ direction using the original small enough area of macro surface \f$\mathrm{d}A\f$:
-
-\f[dA_h = D(h)\,\mathrm{d}h\, \mathrm{d}A\f]
-
-First of all this factor must be positive:
-
-\f[D(h) \geq 0\f]
-
-But the total area of micro faces landscape is at least equal to origin surface but even bigger in general:
-
-\f[1 \leq \int\limits_H D(h)\, \mathrm{d}h\f]
-
-This trait does not allow to use \f$D\f$ as hemisphere distribution.
-But it can be fixed with following feature:
-
-\f[\forall v\, \int\limits_H D(h)(v \cdot h)\, \mathrm{d}h = (v \cdot n)\f]
-
-Which means that total area of micro faces projected to any direction must be the same as projected area of origin macro surface.
-It is pretty tricky trait in \f$D\f$ definition but it leads to interesting results in condition when \f$v = n\f$:
-
-\f[\int\limits_H D(h)\cos\theta_h\, \mathrm{d}h = 1\f]
-
-So that \f$\cos\theta_h\f$ coefficient normalizes normal distribution in terms of hemisphere and allows to use it as distribution.
-Finally PDF of half vectors can be wrote:
-
-\f[p(\theta_h, \phi_h) = D\cos\theta_h\sin\theta_h = \frac{\alpha^2 \cos\theta_h\sin\theta_h}{\pi(\cos^2\theta_h(\alpha^2-1) + 1)^2}\f]
-
-\f$\sin\theta_h\f$ results from spherical coordinate system transfer which was described in Monte-Carlo integration chapter.
-Lets strict to samples generation procedure and find partial probability densities:
-
-\f[p(\phi_h) = \int\limits_0^\frac{\pi}{2} p(\theta_h, \phi_h)\, \mathrm{d}\theta_h = \int\limits_0^\frac{\pi}{2} \frac{\alpha^2 \cos\theta_h\sin\theta_h}{\pi(\cos^2\theta_h(\alpha^2-1) + 1)^2}\, \mathrm{d}\theta = \frac{1}{2\pi}\f]
-
-\f[p(\theta_h) = \int\limits_0^{2\pi} p(\theta_h, \phi_h)\, \mathrm{d}\phi_h = \int\limits_0^{2\pi} \frac{\alpha^2 \cos\theta_h\sin\theta_h}{\pi(\cos^2\theta_h(\alpha^2-1) + 1)^2}\, \mathrm{d}\phi = \frac{2 \alpha^2 \cos\theta_h\sin\theta_h}{(\cos^2\theta_h(\alpha^2-1) + 1)^2}\f]
-
-\f$p(\phi_h)\f$ is unnecessary to be calculated analytically.
-The fact of independency from \f$\phi\f$ is enough to figure out that this coordinate is uniformly distributed.
-Anyway the \f$F(\theta_h)\f$ is next step:
-
-\f[F(\theta_h) = \int\limits_0^{\theta_h} \frac{2 \alpha^2 \cos\theta'_h\sin\theta'_h}{(\cos^2\theta'_h(\alpha^2-1) + 1)^2}\, \mathrm{d}\theta'_h = \int\limits_{\theta_h}^0 \frac{2 \alpha^2}{(\cos^2\theta'_h(\alpha^2-1) + 1)^2}\, \mathrm{d}(\cos^2\theta'_h) = \frac{\alpha^2}{\alpha^2-1}\int\limits_0^{\theta_h} \mathrm{d}\frac{1}{\cos^2\theta'_h(\alpha^2-1)+1} =\f]
-
-\f[ = \frac{\alpha^2}{\alpha^2-1} \left( \frac{1}{\cos^2\theta_h(\alpha^2-1) + 1} - \frac{1}{\alpha^2} \right) = \frac{\alpha^2}{\cos^2\theta_h(\alpha^2-1)^2+(\alpha^2-1)} - \frac{1}{\alpha^2-1}\f]
-
-In order to apply inverse transform sampling the \f$F^{-1}(u)\f$ is needed to be found:
-
-\f[F^{-1}(u) = \theta_h = \arccos\sqrt{\frac{1-u}{u(\alpha^2-1)+1}}\f]
-
-So that there is no more obstacles to generate \f$h\f$.
-But the main goal was \f$l\f$ direction.
-In order to get it the view vector \f$v\f$ has to be reflected related to already found \f$h\f$:
-
-\f[l = 2(v \cdot h)h - v\f]
-
-That is practical side of light direction generation.
-But the theoretical one is needed to be resolved to calculate sum.
-It is time to find \f$p(l)\f$ using known \f$p(h)\f$.
-First of all the fact that \f$l\f$ is just transformed \f$h\f$ is needed to be understood.
-In that way the light direction's PDF has following expression:
-
-\f[p(l) = p(h)|J_T|\f]
-
-Where \f$|J_T|\f$ is Jacobian of reflection transformation.
-Lets find it.
-Right now \f$n\f$ is axis from which \f$\theta\f$ spherical coordinate is encountered.
-The first step is setting \f$v\f$ as starting point of \f$\theta\f$ instead of \f$n\f$.
-This is linear transform so that \f$|J_T| = 1\f$.
-Next step is transfer to spherical coordinate with \f$|J_T| = \sin\theta_{vh}\f$.
-Due to previous step \f$\theta_{vh}\f$ is used instead of \f$\theta_h\f$.
-In this coordinate system reflecting of \f$v\f$ relative to \f$h\f$ is just doubling \f$\theta_{vh}\f$ and Jacobian of it is equal to \f$\frac{1}{2}\f$.
-In series of transform the Jacobians are multiplied so that currently \f$|J_T| = \frac{1}{2}\sin\theta_{vh}\f$.
-And the final step is inverse transform to Cartesian coordinate system with \f$|J_T| = (\sin\theta_{vl})^{-1} = (\sin2\theta_{vh})^{-1}\f$.
-Combining this all together the following expression is obtained for reflection transform Jacobian:
-
-\f[|J_T| = \frac{\sin\theta_{vh}}{2\sin2\theta_{vh}} = \frac{\sin\theta_{vh}}{4\sin\theta_{vh}\cos\theta_{vh}} = \frac{1}{4\cos\theta_{vh}}\f]
-
-And finally \f$p(l)\f$ looks like:
-
-\f[p(l) = p(h)|J_T| = \frac{D\cos\theta_h}{4\cos\theta_{vh}}\f]
-
-Lets go back to the Monte-Carlo sum and insert found result to it:
-
-\f[\int\limits_H \frac{DG}{4\cos\theta_v \cos\theta_l} g(v, l) \cos\theta_l\, \mathrm{d}l \approx \frac{1}{N} \sum_{i=1}^N \frac{DG\, g(v, l_i) \cos\theta_{l_i}}{4\cos\theta_v \cos\theta_{l_i}\, p(l_i)} = \frac{1}{N} \sum_{i=1}^N \frac{G\, g(v, l_i) \cos\theta_{l_i} \cos\theta_{vh_i}}{\cos\theta_v \cos\theta_{l_i} \cos\theta_{h_i}}\f]
-
-Here \f$G\f$ component is recommended to be calculated with original \f$k=\frac{\alpha}{2} = \frac{r^2}{2}\f$ in order to get more plausible result.
-Of course, all \f$\cos\f$ must be clamped to range \f$[0, 1]\f$ because integral is calculated on a hemisphere and all expressions are defined on it.
-\f$\cos\theta_v \cos\theta_{l_i}\f$ in denominator can be reduced with exactly the same part in geometric attenuation factor in order to avoid additional zero division cases.
-
-Summarizing importance sampling strategy described above the convergence of Monte-Carlo integration can be improved using special PDF correlated with integrated function.
-In case of BRDF with normal distribution functions \f$D\f$ the PDF producing procedure is defined.
-Practically half vector \f$h\f$ is generated first and \f$l\f$ is obtained from it by view vector \f$v\f$ reflecting.
-Due to this transformation final form of probability density used in sum is quite different but also has defined algorithm of calculation.
-For isotropic Cook-Torrance BRDF the \f$\cos\theta_v\f$ and roughness \f$r\f$ are enough to start generation so that all integrals of that kind can be precalculated in 2D look-up tables variating these two parameters.
-The same samples generation procedure must be used in specular map baking described in next chapter.
-
-# Specular map
-
-The situation with BRDF part of \f$L_{indirect}^s\f$ is clear now and \f$L_i^{indirect}(l)\f$ sum is left to be discussed.
-That was called **specular map** and has following form:
-
-\f[\frac{1}{N}\sum_{i=1}^N L_i^{indirect}(l_i)\f]
-
-As was mentioned this sum must be calculated for every normal direction using the same samples generation principles as in numeric integration computation.
-This principles require two scalar parameters \f$\cos\theta_v\f$ and \f$r\f$ but now \f$\phi\f$ really matters.
-So that in fact the specular map has to be saved in 3D table consisting omnidirectional textures.
-That is a big expense of computational and memory resources.
-A couple of tricks helps to reduce dimensions.
-First of all the \f$\cos\theta_v\f$ and \f$\phi\f$ can be just excluded.
-In that way \f$v\f$ is considered to be equal to \f$n\f$.
-Of course this approach produces an error and affects the final result.
-It can be fixed more or less by \f$\cos\theta_{l_i}\f$ weighting:
-
-\f[\frac{1}{N} \sum_{i=1}^N L_i^{indirect}(l_i) \cos\theta_{l_i}\f]
-
-It is not a complete solution but practice shows that it is enough to get plausible illumination with sacrificing of lengthy reflections at grazing angles which exist in fact if everything is honestly computed.
-The problem is that for \f$v \neq n\f$ considering this sum to be defined related to \f$n\f$ became incorrect.
-For example, for complete mirroring materials with \f$r = 0\f$ this sum must boil down to \f$L_i^{indirect}(v_r)\f$
-but not to \f$L_i^{indirect}(n)\f$ where \f$v_r\f$ is just reflected \f$v\f$ or in other words \f$v_r = 2(v \cdot n)n - v\f$.
-That it just mirroring reflection principle.
-Assumption of \f$n = v\f$ also means that \f$n = v = v_r\f$.
-In that way radiance map better to be considered as averaging of illumination coming from \f$v_r\f$.
-So that it has become to be defined related to reflection direction which has to be calculated before map's fetching.
-
-Anyway, there are just two dimensions in radiance look-up table remain.
-The rest one with \f$r\f$ parameter cannot be reduced.
-There is no other ways except just roughness variation but in order to simplify that computations can be done for several values and the rest ones lying between can be obtained from linear interpolation.
-This is another source of visual artifacts but it also works good in practice and that is pretty common approach.
-But it still requires noticeably amount of samples and that is for every pixel related to each \f$r\f$ value.
-It can be appropriate for precomputations but still limits using dynamic environments in real time rendering or just even static environments but on weak devices such as mobile ones.
-And there are several possible ways to improve radiance map baking performance.
-
-The first one is using textures with smaller resolutions for larger roughnesses.
-The point is that smaller \f$r\f$ values produce map saving more details from origin environment in opposite to larger ones representing lower frequency components and working as low pass filters in fact.
-So less pixels in combination with linear interpolation is enough to store less detailed convolutions.
-Moreover, this approach naturally works with textures levels of details in graphics API
-so that every certain radiance map related to certain \f$r\f$ can be stored on its own mip level and be directly fetched with linear interpolation not only over one texture but over levels too.
-As practice shows 6 levels are enough.
-
-After reducing pixels count it is turn for samples number.
-And again correlation with roughness can be noticed.
-For example map for completely mirroring materials with \f$r = 0\f$ the same sample \f$l_i = v_r\f$ will be produced.
-So that only one sample is enough in this case.
-In opposite way directions for \f$r = 1\f$ will be scattered over almost whole hemisphere what requires as much samples as available.
-The 'locality' of distribution is decreased during increasing roughness and it is possible to assume that samples number might to be proportional to this 'locality' keeping accuracy at the same level.
-But how can 'locality' be interpreted in terms of probability distribution? One possible way is CDF meaning.
-\f$F(\theta_h)\f$ has been already defined and by definition it shows the probability of random value \f$\theta_h\f$ to be less than argument of CDF.
-In other words \f$F(\theta'_h) = u\f$ means that probability of \f$\theta_h\f$ to be in range of \f$[0, \theta'_h]\f$ is \f$u\f$.
-The inverse task of range searching using given \f$u\f$ can be solved with help of \f$F^{-1}(u) = \theta'_h\f$.
-If \f$u\f$ is close to 1 (exact 1 has no sense because in that case \f$\theta'_h = \max\theta_h = \frac{\pi}{2}\f$)
-then \f$\theta'_h\f$ represents the range of the most probable or most frequently generated values and that can be interpreted as 'locality' of distribution.
-After that if samples number of the worst case with \f$r = 1\f$ is set (\f$N(1) = \max N\f$) the other ones can be estimated using following formula:
-
-\f[N(r) = N(1)\frac{\theta'_h(r)}{\frac{\pi}{2}} = N(1)\frac{2\theta'_h(r)}{\pi} = N(1)\frac{2F^{-1}(u)}{\pi} = N(1)\frac{2}{\pi}\arccos\sqrt{\frac{1-u}{u(\alpha^2-1)+1}}\f]
-
-It is approximate expression representing only estimated general proportionality so that cases of \f$r = 0\f$ and \f$r = 1\f$ must be processed separately with \f$N(0) = 1\f$ and \f$N(1) = \max N\f$.
-\f$u\f$ can be parameter of this optimization strategy controlling speed of samples reducing in order to balance performance and quality (\f$u = 1\f$ disables this optimization at all).
-This pretty tricky technique allows reducing calculations for every pixels without sacrificing the quality.
-
-In addition to optimizations mentioned before another one can be applied in order to help to reduce samples numbers as previous one.
-Using less samples produces image noise due to discrete nature of Monte-Carlo approximation.
-But it can be slightly smoothed using some prefiltration.
-The idea is that for the directions with small PDF or in other words for rare directions the samples near of it is unlikely to be generated.
-So that this direction represents the averaged illumination from relatively big area on hemisphere but approximate it by just a constant.
-It wold be better to get from such direction already averaged over bigger area environment.
-It can be achieved using mip levels of origin \f$L_i^{indirect}\f$ whose pixels of one level is exact 4 averaged pixels from previous one.
-Also mip levels generation is build in most common graphic API so there are no problems with it.
-But first of all the area covered by one sample is needed to be found.
-And that can be done as:
-
-\f[\Omega_s = \frac{1}{N\,p(l)} = \frac{4\cos\theta_{vh}}{ND\cos\theta_h}\f]
-
-Circumstance of \f$v = v_r = n\f$ leads to \f$\cos\theta_{vh}\f$ and \f$\cos\theta_h\f$ reducing so expression becomes even simpler:
-
-\f[\Omega_s =\frac{4}{ND}\f]
-
-Of course all zero divisions must be avoided by clamping, for example.
-After that the area covered by one pixel of environment map is calculated.
-In case of a cube map it looks like:
-
-\f[\Omega_p = \frac{4\pi}{6k^2}\f]
-
-Where \f$k\f$ is size of one cube map side in pixels (sides are assumed to be quads).
-Finally the mip level of origin environment map which is needed to be fetched for this certain sample is defined by following expression:
-
-\f[lod = \frac{1}{2} \log_2\left(\frac{\Omega_s}{\Omega_p}\right)\f]
-
-The mathematics connected with mip levels sizes lie behind it but this is out of scope of this paper.
-In combination with previous optimization technique this approach allows \f$N(1)\f$ to be smaller keeping visual results good.
-
-That is not all possible optimization tricks but at least these three significantly reduces compute efforts and brings radiance map calculation to weak devices or even to dynamic environments in real time but in reasonable limits.
-
-In that way \f$L_{indirect}^s\f$ can be completely computed without any integral approximations.
-Only 2D look-up table of BRDF part and mip mapped omnidirectional texture of irradiance map are needed.
-The first one can be got even without any environment.
-It was achieved using some rough approximations and assumptions but despite of that the visual result are still plausible and can be compared even with ray traced images.
-In order to complete whole image based lighting the \f$L_{indirect}^d\f$ component is left to be discussed.
-
-# Spherical harmonics
-
-Lets go back to diffuse indirect illumination component represented by following formula:
-
-\f[L_{indirect}^d = (1-m)\frac{c}{\pi}\int\limits_H (1-F)L_i^{indirect}(l)\cos\theta_l\, \mathrm{d}l\f]
-
-Of course, Monte-Carlo algorithm can be applied directly and hemisphere integral can be precalculated for every normal direction
-but dependence from \f$v\f$ in Fresnel's factor does not allow to do it efficiently (every \f$v\f$ direction is needed to be considered again).
-In order to resolve it modified version of Schlick's approximation has been created:
-
-\f[F \approx F_{ss}=F_0+(\max(1-r, F_0))(1-\cos\theta_v)^5\f]
-
-It differs from origin one and loses accuracy a little bit but now there is no light direction inside
-so that it can be considered as kind of screen space defined Fresnel's factor (\f$ss\f$ means exactly 'screen space') and can be removed from integral:
-
-\f[L_{indirect}^d = (1-m)(1-F_{ss})\frac{c}{\pi} \int\limits_H L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-The resulted expression without \f$(1-m)\f$ and \f$(1-F_{ss})\f$ parts is pretty known entity called **irradiance**.
-It can be precalculated using \f$\cos\theta_l\f$ as PDF for importance sampling (actually it is only option in this case excluding uniform distribution).
-But even with that samples will be scattered almost over whole hemisphere.
-As was discussed in previous chapter this case requires significant amount of samples in order to average illumination with appropriate quality.
-Poor accuracy resulted from lack of summand can be noticed especially on high frequency environments having a lot of contrasting details.
-It worth to be mentioned that irradiance is used not only in BRDF.
-Omnidirectional diffuse illumination captured for certain point or even for several points uniformly or hierarchically distributed is base of some baking global illumination techniques.
-There it is called a **light probe**. So that other way to compute and store irradiance maps was found resolving many mentioned problems.
-The Fourier's decomposition analogue for spherical function allows to achieve this.
-That would be easy to explain concept directly on example.
-So lets start from \f$L_i^{indirect}(l)\f$.
-It is spherical function because directions are just points on sphere.
-The decomposition looks like:
-
-\f[L_i^{indirect}(l) = \sum_{i = 0}^\infty \sum_{j=-i}^i L_i^j y_i^j(l)\f]
-
-Where \f$y_i^j(l)\f$ are spherical functions forming orthonormalized basis called spherical harmonics and \f$L_i^j\f$ is decompositions coefficients.
-Orthonormality means that dot product of two basis elements is equal to 1 if this is the same functions and is equal to zero otherwise.
-Dot product on a sphere is defined as integral of functions multiplication. In other words:
-
-\f[\int\limits_S y_i^j(l)\, y_{i'}^{j'}(l)\, \mathrm{d}l = \begin{cases} 1 & \quad i,j = i',j' \\ 0 & \quad \mathrm{otherwise}\end{cases}\f]
-
-Function basis with such traits is known and is described by following formulas:
-
-\f[y_i^{j > 0}(\theta, \phi) = \sqrt{2}K_i^j\cos(j\phi)P_i^j(\cos\theta)\f]
-\f[y_i^{j<0}(\theta, \phi) = \sqrt{2}K_i^j\sin(j\phi)P_i^{|j|}(\cos\theta)\f]
-\f[y_i^0(\theta, \phi) = K_i^0P_i^0(\cos\theta)\f]
-
-\f[K_i^j = \sqrt{\frac{(2i+1)(i-|j|)!}{4\pi(i+|j|)!}}\f]
-\f[P_0^0(x) = 1\f]
-\f[P_1^0(x) = x\f]
-\f[P_i^i(x) = (-1)^i(2i-1)!!(1-x^2)^\frac{i}{2}\f]
-\f[P_i^j(x) = \frac{(2i-1)xP_{i-1}^j(x) - (i + j - 1)P_{i-2}^j}{i - j}\f]
-
-Here \f$K_i^j\f$ are normalization factors and \f$P_i^j\f$ are **Legendre's polynomials**.
-Decomposition coefficients \f$L_i^j\f$ are dot product of origin function (\f$L_i^{indirect}(l)\f$ in current case) and corresponding basis element. It can be written down as:
-
-\f[L_i^j = \int\limits_S L_i^{indirect}(l)\,y_i^j(l)\, \mathrm{d}l\f]
-
-Fact that all calculation happen over a sphere but not over hemisphere right now is important not to be missed.
-That was example of spherical function decomposition but not a solution for original task which looks like:
-
-\f[\int\limits_H L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l\f]
-
-First of all, lets transform this integral to be defined not over hemisphere but sphere:
-
-\f[\int\limits_H L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l = \int\limits_S L_i^{indirect}(l)\overline{\cos}\theta_l\, \mathrm{d}l\f]
-
-Where \f$\overline{\cos}\f$ is cosine clamped to zero which can be expressed as:
-
-\f[\overline{\cos}\theta_l = \max(\cos\theta_l, 0)\f]
-
-Resulted expression can be considered as convolution in terms of spherical functions where \f$L_i^{indirect}(l)\f$ is target and \f$\overline{\cos}\theta_l\f$ is core.
-This integral may seem independent but in fact hemisphere is oriented related to \f$n\f$ therefore \f$\overline{\cos}\theta_l\f$ depends on it too and became a kind of 'oriented' version of cosine.
-That is pretty tricky and explanation about meaning of convolution on sphere is out of scope of this paper.
-Fact that this is convolution analogue related to \f$n\f$ is enough for now.
-The goal of looking at integral from this angle is using of convolution's trait allowing to compute decomposition using just only coefficients of function and core.
-\f$\overline{\cos}\theta_l\f$ is independent from \f$\phi_l\f$ and in case of such radial symmetric cores the resulting coefficients boil down to following formula:
-
-\f[(L_i^{indirect}(l) \ast \overline{\cos}\theta_l)_i^j = \frac{1}{K_i^0}L_i^j\, c_i^0 = \sqrt{\frac{4\pi}{2i+1}}L_i^j\, c_i^0\f]
-
-Where \f$c_i^0\f$ are spherical harmonics factors corresponding to \f$\overline{\cos}\theta\f$.
-Therefore the final decomposition looks like:
-
-\f[\int\limits_{H(n)} L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l = \int\limits_S L_i^{indirect}(l)\overline{\cos}\theta_l\, \mathrm{d}l = \sum_{i=0}^\infty \sum_{j = -i}^i \sqrt{\frac{4\pi}{2i+1}}L_i^j\, c_i^0\, y_i^j(n)\f]
-
-\f$c_i^0\f$ is left to be found.
-Due to independence from \f$\phi\f$ all \f$c_i^{j \neq 0} = 0\f$.
-The rest ones are calculated by regular dot product with basis functions:
-
-\f[c_i^0 = c_i = \int\limits_S y_i^0(l)\, \overline{\cos}\theta_l\, \mathrm{d}l = \int\limits_0^{2\pi} \mathrm{d}\phi \int\limits_0^\pi y_i^0(\theta, \phi)\, \overline{\cos}\theta \sin\theta\, \mathrm{d}\theta = \int\limits_0^{2\pi} \mathrm{d}\phi \int\limits_0^\frac{\pi}{2} y_i^0(\theta, \phi)\, \cos\theta\sin\theta\, \mathrm{d}\theta = \f]
-
-\f[= 2\pi\int\limits_0^\frac{\pi}{2} y_i^0(\theta, \phi)\, \cos\theta\sin\theta\, \mathrm{d}\theta = 2\pi K_i^0\int\limits_0^\frac{\pi}{2} P_i^0(\cos\theta)\, \cos\theta\sin\theta\, \mathrm{d}\theta\f]
-
-\f$\sin\theta\f$ appears due to transfer from integral over sphere to double integral where \f$\mathrm{d}l = \sin\theta\, \mathrm{d}\theta\, \mathrm{d}\phi\f$.
-There is an analytical solution for this expressions:
-
-\f[c_1 = \sqrt{\frac{\pi}{3}}\f]
-
-\f[c_{odd} = 0 \quad c_{even} = 2\pi\sqrt{\frac{2i+1}{4\pi}}\frac{(-1)^{\frac{i}{2}-1}}{(i+2)(i-1)}\frac{i!}{2^i\left(\frac{i!}{2}\right)^2}\f]
-
-Starting from about the third \f$c_i\f$ the coefficients become less and less valuable so that only couple of them is enough in order to approximate \f$\overline{\cos}\theta\f$ with appropriate accuracy.
-The same principle is true for convolution too because its coefficients are multiplied by \f$c_i\f$.
-So there is no need to use more than even three bands (\f$i = 0, 1, 2\f$) of basis functions.
-Lets write down them all in Cartesian coordinate system:
-
-\f[y_0^0 = \frac{1}{2}\sqrt{\frac{1}{\pi}} = Y_0^0\f]
-
-\f[y_1^{-1} = -\frac{1}{2}\sqrt{\frac{3}{\pi}}y = Y_1^{-1}y\f]
-\f[y_1^0 = \frac{1}{2}\sqrt{\frac{3}{\pi}}z = Y_1^0z\f]
-\f[y_1^1 = -\frac{1}{2}\sqrt{\frac{3}{\pi}}x = Y_1^1x\f]
-
-\f[y_2^{-2} = \frac{1}{2}\sqrt{\frac{15}{\pi}}xy = Y_2^{-2}xy\f]
-\f[y_2^{-1} = -\frac{1}{2}\sqrt{\frac{15}{\pi}}yz = Y_2^{-1}yz\f]
-\f[y_2^0 = \frac{1}{4}\sqrt{\frac{5}{\pi}}(3z^2-1) = Y_2^0(3z^2-1)\f]
-\f[y_2^1 = -\frac{1}{2}\sqrt{\frac{15}{\pi}}xz = Y_2^1xz\f]
-\f[y_2^2 = \frac{1}{4}\sqrt{\frac{15}{\pi}}(x^2-y^2) = Y_2^2(x^2-y^2)\f]
-
-All \f$Y_i^j\f$ are just constants so that it can be moved from integral during calculations and can be taken from precomputed table.
-Other constants related to \f$c_i\f$ can be united and also be calculated beforehand:
-
-\f[\hat{c}_i = \frac{1}{K_i^0}\, c_i = \sqrt{\frac{4\pi}{2i+1}}\, c_i\f]
-
-Finally expression of irradiance map approximation can be defined:
-
-\f[\int\limits_{H(n)} L_i^{indirect}(l) \cos\theta_l\, \mathrm{d}l \approx \sum_{i=0}^2 \sum_{j=-i}^i L_i^j\, \hat{c}_i\, y_i^j(n)\f]
-
-Where \f$\hat{c}_i\f$ is precalculated constants \f$y_i^j(n)\f$ are pretty easy functions and only \f$L_i^j\f$ are needed to be precomputed.
-Of course \f$L_i^j\f$ are integrals over even whole sphere but now there is only nine of it instead of one for every pixel of omnidirectional image.
-Moreover, texture is not needed at all in that case and only 9 colors representing \f$L_i^j\f$ have to be saved.
-The Monte-Carlo algorithm can be applied with just uniform samples distribution without importance sampling at all.
-\f$Y_i^j\f$ are used twice: in \f$L_i^j\f$ calculations and in sum after that.
-So there is sense to store only squares of it.
-All tables with constants presented below:
-
-| |
-|-|
-| \f$(Y_0^0)^2 \approx (0.282095)^2\f$ |
-| \f$(Y_1^{-1})^2 = (Y_1^0)^2 = (Y_1^1)^2 \approx (0.488603)^2\f$ |
-| \f$(Y_2^{-2})^2 = (Y_2^{-1})^2 = (Y_2^1)^2 \approx (1.092548)^2\f$ |
-| \f$(Y_2^0)^2 \approx (0.315392)^2\f$ |
-| \f$(Y_2^2)^2 \approx (0.546274)^2\f$ |
-
-| | |
-|-|-|
-| \f$\hat{c}_0\f$ | \f$3.141593\f$ |
-| \f$\hat{c}_1\f$ | \f$2.094395\f$ |
-| \f$\hat{c}_2\f$ | \f$0.785398\f$ |
-
-Summarizing all mathematics above spherical harmonics decomposition boils down irradiance map to only 9 values which is needed to be precalculated as integrals.
-As practice shows this is very good approximation of diffuse indirect illumination component.

-@subsection occt_algorithms_bop_on_opensolids Boolean operations on open solids
-
-The Boolean operations on open solids are tricky enough that the standard approach of Boolean operations for building the result, based on the splits of solids does not work.
-It happens because the algorithm for splitting solids (*BOPAlgo_BuilderSolid*) always tries to create the closed loops (shells) and make solids from them. But if the input solid is not closed, what can be expected from its splits?
-For performing Boolean Operations on open solids another approach is used, which does not rely on the splits of the solids to be correct, but tries to select the splits of faces, which are necessary for the given type of operation.
-The point here is that the type of Boolean operation clearly defines the states for the faces to be taken into result:
-- For **COMMON** operation all the faces from the arguments located inside any solid of the opposite group must be taken;
-- For **FUSE** operation all the faces from the arguments located outside of all solids of the opposite group must be taken;
-- For **CUT** operation all the faces from the Objects located outside of all solids of the Tools and all faces from the Tools located inside any solid of the Objects must be taken;
-- For **CUT21** operation all the faces from the Objects located inside any solid of the Tools and all faces from the Tools located outside of all solids of the Objects must be taken.
-From the selected faces the result solids are built. Please note, that the result may contain as normal (closed) solids as the open ones.
-
-Even with this approach, the correct result of Boolean operation on open solids cannot be always guaranteed.
-This is explained by non-manifold nature of open solids: in some cases classification of a face depends on the point of the face chosen for classification.

-
-The API algorithms implementing Boolean Operations provide possibility to simplify the result shape by unification of the connected tangential edges and faces.
-This simplification is performed by the method *SimplifyResult* which is implemented in the class *BRepAlgoAPI_BuilderAlgo* (General Fuse operation).
-It makes it available for users of the classes *BRepAlgoAPI_BooleanOperation* (all Boolean Operations) and *BRepAlgoAPI_Splitter* (split operation).
-
-The simplification is performed by the means of *ShapeUpgrade_UnifySameDom* algorithm. The result of operation is overwritten with the simplified result.
-
-The simplification is performed without creation of the Internal shapes, i.e. shapes connections will never be broken. It is performed on the whole result shape.
-Thus, if the input shapes contained connected tangent edges or faces unmodified during the operation they will also be unified.
-
-History of the simplification is merged into the main history of operation, thus it will be accounted when asking for Modified, Generated and Deleted shapes.
-
-Some options of the main operation are passed into the Unifier:
-- Fuzzy tolerance of the operation is given to the Unifier as the linear tolerance.
-- Non destructive mode here controls the safe input mode in Unifier.
