- SelectMgr_OrFilter don't store the disabled objects, it's stored in SelectMgr_AndOrFilter
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Added V3d_View::SetBackgroundImage() accepting Graphic3d_Texture2D on input.
Graphic3d_CView/OpenGl_View have been modified to merge Graphic3d_CView::SetBackgroundImage()
and ::SetBackgroundCubeMap() implementations into a single method.
- Update .step scanner:
- add rules to read anything within the comment
- add a function to initialize of lexical scanner
- add states for Commit & End instead of global variables modcom & modend
Added possibility to inherit existing attributes if the same persistent fields are used. All methods that allow controlling the data model changes or getting some callbacks may be overridden in successor. They may have same GUIDs as a base class or new ones.
Special macros IMPLEMENT_DERIVED_ATTRIBUTE and IMPLEMENT_DERIVED_ATTRIBUTE_WITH_TYPE must be used instead of standard Handle macro definition IMPLEMENT_STANDARD_RTTIEXT to register new derived attributes.
Using this improvement several existing attributes from TDataStd, TDataXtd and XCAFDoc packages become inherited from other base attribute-classes. XML and Bin drivers of these attributes are removed. New base attribute classes are added: TDataStd_GenericEmpty and TDataStd_GenericExtString.
This improvement does not change both present formats Bin and XML documents. The obsolete Standard scheme is not changed at all.
InitFromJson method implementation for some simple classes.
OCCT_INIT_* defines introduction to do automatic parsing of the stream into values.
Inspector is extended to visualize objects created on the dump stream if it might be created.

The files build.bat and install.bat are copied to the build directory by cmake configure procedure to enable batch building and installation on Windows platform.
The scripts occ_build_wasm.bat and occ_build_wasm.sh have been added
to simplify batch building of OCCT with Emscripten (Web Assembly packages) correspondingly on Windows and Linux platforms.
These scripts are configurable through calling files with custom environment wasm_custom_env.bat and wasm_custom_env.sh.
Added public method Font_FontMgr::AddFontAlias() for registering custom aliases and fallback fonts.
vfont command has been extended with arguments -aliases, -addAlias, -removeAlias, -clearAlias and -clearAliases.
Scripts adm/cmake/bison.cmake and adm/cmake/flex.cmake are refactored to enable actual search for bison and flex.
Apart of standard locations, also sub-folders of 3RDPARTY_DIR whose names contain "bison" and "flex", respectively, are added to search.
Cache variables 3RDPARTY_BISON_EXECUTABLE and 3RDPARTY_FLEX_EXECUTABLE are removed to avoid confusion (they duplicated similar variables without "3RDPARTY_" prefix).
Lex and Yacc files are corrected to match changes made manually in generated files during last years:
- StepFile/step.yacc: correction missing from #22972
- StepFile/step.lex: corrected for compilation (broken by #31060)
- MSVC-specific code is synchronized between StepFile/step.lex and ExprIntrp/ExprIntrp.lex
- Old commented code and duplicate code blocks removed
Commands for execution of Flex and Bison tools in CMake scripts are tweaked to avoid embedding line numbers (with local paths) in generated files.
Scanners and parsers are regenerated from updated source files with modified options.
Note that lex.ExprIntrp.c is regenerated with multiple differences because option -f (fast scanner) was used for generation of previous version (by WOK).
Draw_Interpretor, CommandCmd() - catched exceptions and messages put into Tcl string result
before throwing a Tcl exception (return 1) are now print in intense red (using Message::SendFail()).
Duplication of exception message in std::cout and Tcl output has been removed.
Draw Harness plugins have been updated to use either Message::SendFail() or theDI instead of std::cout/std::cerr
for printing colored error message before throwing a Tcl exception.
Handle "VTK::" prefix instead of "vtk" used by previous VTK versions for targets.
Corrected unexpected location of endif() and broken indentation.

Default MSAA settings have been changed from 8 to 0 to match vinit behavior.
Added command ivtkclose closing a Vtk view.
Added commands ivtkaxo, ivtkfront, ivtkback, ivtkleft, ivtkright,
ivtktop and ivtkbottom assigning view projection similar to sonamed commands in ViewerTest.
Added commands ivtksetcolor and ivtksettransparency assigning
color properties to shaded presentation.
Methods ParseOnOff()/ParseColor() have been moved from package ViewerTest to Draw.

Add tests of ProgressIndicator in TDocStd_Applacation.
# Add test to verify import
* Note: Each layer contains a valid name, but only one contains a link to the shape, so .step file contains only one valid Layer.
gp_Trsf::SetRotationPart() - added method replacing rotation matrix without reseting other components,
similar to existing SetTraslationPart() and SetScaleFactor().
Transformation multiplication order has been fixed
for vlocation arguments -rotate, -translate, -mirror and -scale.
Added -prerotate, -pretranslate, -premirror and -prescale options following previous behavior.
vlocation -setRotation now uses new method gp_Trsf::SetRotationPart()
for consistency with methods -setLocation and -setScale.
OpenGl_Context now skips loading functions related to mapping buffer,
which are required by OpenGL ES 3.0 specs but not provided by WebGL 2.0.
Message_PrinterSystemLog does not use a broken emscripten_log() anymore, which corrupted UNICODE strings.
WasmOcctView::initWindow() - callbacks now set using EMSCRIPTEN_EVENT_TARGET_WINDOW
instead of 0 used by older Emscripten API.
Mouse callbacks now track canvas element and use
EmscriptenMouseEvent::targetX/targetY instead of ::canvasX/canvasY
as the latter was broken.
Added emscripten_set_main_loop() setup to shut up eglSwapInterval() error message.
Fixed missing \0 at the end of string converted by toUtf8Array().
Improve projection of ellipse and circle on a plane in case of the same parametrization of the original curve and the projected one is not necessary. Now the projection is a canonical curve instead of B-spline.

ElSLib.cxx : method TorusParameters(...) is modified to avoid divide by zero
math_PSOParticlesPool.cxx : initialization of array is added
OpenGl_ShaderManager::GetBgCubeMapProgram() and OpenGl_BackgroundArray::createCubeMapArray()
have been corrected to draw cube in straightforward way instead of a screen-quad.
Graphic3d_Camera::SetCustomStereoProjection() now recieves decomposed projection + head-to-eye matrices.
Added method Graphic3d_Camera::StereoProjection() returning projection matrix without translation part.
OpenGl_BackgroundArray::Render() now applies stereoscopic projection matrix in case of VR output,
but keeps using mono projection matrix in case of common 3D displays.
PrsMgr_PresentationManager::displayImmediate() now uses proper ZLayer for a shadow presentation
of computed presentation (fixes dynamic highlighting on mouse move).
Graphic3d_CView::SetComputedMode() - added invalidation of bounding box on turning OFF compute mode.
AIS_ViewController::contextLazyMoveTo() now ignores MoveTo() while rotating
view with temporary disabled compute mode (leading to undefined results and crashes).
Graphic3d_Structure::Graphic3d_Structure() - do not copy Graphic3d_TOS_COMPUTED visual
from linked structure, as Graphic3d_CView::SetComputedMode() does not compute such structures.
SelectMgr_SelectingVolumeManager::SetViewClipping() now updates clipping range
using picking ray in world coordinates, as clipping planes are always defined in world space.
The text label is selected as a rectangle (adds a sensitive object - Select3D_SensitiveFace).
The bounding box has been resized to fit the sensitive rectangle.
Transform persistent has been added to AIS_TextLabel to correctly position the sensitive rectangle.
The findConnectedObject function has also been changed to correctly set transform persistence.

Axonometric view hotkey A has been replaced by Backspace.
Shaded/Wireframe are now mapped with hotkeys W+Ctrl/S+Ctrl.
Hotkey D (reset view to undefined default state) has been removed.
SelectMgr_RectangularFrustum now handles degenerated triangle as a segment or a point.
Triangle orthogonal to view direction is now handled as a segment.
myViewRayDir field is now defined as normalized vector to avoid confusing math.
For the case when the segment and myViewRayDir are almost parallel,
the segmentSegmentDistance function may set the depth to zero, although this will not
be the correct value, therefore it is better to pass a segment that will not
be parallel to myViewRayDir as an argument to the function.
vpoint command has been extended by arguments -2d and -nosel
for displaying picking mouse position as on-screen point in pixels.
Fixed double-binding-map error in case of displaying point with already used name.
bugs/vis/bug31412: test case added.

Redundant OcctJni_Window has been replaced by Aspect_NeutralWindow.
SD Card permissions are not dynamically requested for compatibility with Android API level 26+.
In the TDocStd_Owner keep simple pointer to TDocStd_Document instead of Handle. This causes automatic destruction of the document without explicit call of Close.
In Standard_Type added a static variable theType that initializes theRegistry map earlier. Otherwise exit from Draw interpreter crashes in many test-cases because not-closed transactions are aborted on document handle release from Draw theVariables map.
Corrected method for test OCC159bug due to the fact that Owner does not add a ref count now
Close the document in the end of bugs xde bug22776 otherwise double remove of visualization objects (on library exit and on visualization attributes remove from the document) causes crash on exit from draw

BRepLib_MakeWire.cxx:
in method BRepLib_BndBoxVertexSelector::Accept() accepting tolerance criterion is changed
BRepLib_MakeWire.hxx:
correctionof class field name

Default implementation detects DDS image files using Image_DDSParser parser.
Graphic3d_TextureRoot::GetImage() has been extended with new parameter
- the list of image formats supported by OpenGL driver.
Graphic3d_TextureRoot::convertToCompatible() implicitly converts
BGRA image to RGBA on OpenGL ES, which normally does not support BGR formats.
OpenGl_Caps::isTopDownTextureUV - new property defines how application defines
UV texture coordinates in primitive arrays.
OpenGl_Context::SetTextureMatrix() compares this flag with OpenGl_Texture::IsTopDown()
and automatically flips V coordinate in case of mismatch.
OpenGl_Texture now holds exact number of mipmap levels
instead of Boolean flag indicating that they are defined.
This allows loading DDS files with incomplete mipmap level set
by setting GL_TEXTURE_MAX_LEVEL to appropriate value instead of default 1000
(causing black textures in case if mipmap levels are not defined till 1x1).
Fixed order of texture coordinates transformation within GLSL program to match FFP matrix:
Rotate -> Translate -> Scale (previously Rotation was applied afterwards).
Fixed -Wrestrict warning within OSD::SetSignal().
Fixed -Wdeprecated-copy warning by adding missing counterpart
in pair copy constructor / assignment operator or by removing trivial constructor.
AdvApp2Var_Node, AdvApp2Var_Patch are now declared as Handle.

tests/bugs/modalg_5/bug25232_8 : test is modified according to new behavior of algorithms
- Issue is done in previous version OCCT
- Add test to verify the creating of the label structure using plain OCAF/XDE API
- Situation when the assembly label has no shape attached is correct
The argument putEndl has been removed from Message_Messenger::Send() and Message_Printer::Send() methods.
Message_Printer interface has been changed, so that sub-classes have to implement new method
Message_Printer::send() accepting TCollection_AsciiString.
Old three Message_Printer::Send() methods remain available without putEndl argument
and redirecting to new send() method by default.
Removed dummy Message_PrinterOStream::GetUseUtf8() property.
Message_PrinterOStream, Message_PrinterSystemLog and Draw_Printer
now implement single method Message_Printer::send() instead of triplet.
Operators << for Handle(Message_Messenger) are removed; their use is replaced by use of Message_Messenger::StreamBuffer
Message_Messenger has been replaced by Standard_OStream within Interface_InterfaceModel,IFSelect,IGES,STEP dump interfaces.
Class Standard_BaseDriver is inherited from Standard_Transient, its descendants are updated accordingly.
Handle is used to manipulate objects of this class and its descendants (instead of references or raw pointers) to ensure automatic destruction.
Added test bugs caf bug31546
Related:
- Standard_OVERRIDE is added in declarations of virtual methods in descendants of Storage_BaseDriver

- Private field Standard_Transient::count is renamed to myRefCount_ to avoid compiler warnings if the same name is used within the scope of a descendant class
- Output of meaningful error messages is restored in DRAW commands fsdread and fsdwrite
V3d_View::AutoZFit() is now called only before redraw
within methods V3d_View::Redraw() and V3d_View::Update().
Graphic3d_CView now holds Aspect_ExtendedRealitySession object.
Aspect_OpenVRSession implements new interface via optional OpenVR library.
Graphic3d_CView::ProcessInput() - added new interface method
which should be called for processing positional input (head tracking).
Graphic3d_Camera now allows setting custom stereoscopic Projection matrices.
OpenGl_Context::Camera() - context now holds Camera object
in addition to active camera matrices.

SelectMgr_SortCriterion::Normal, SelectBasics_PickResult::SurfaceNormal() - added new property.
SelectMgr_RectangularFrustum::Overlaps() for triangle sets new normal property.
gp_GTrsf::GetMat4() - added conversion into NCollection_Mat4 similar to gp_Trsf::GetMat4().
Added short-cuts methods in Message_Messenger for sending message with specified gravity,
and stream buffer class for using stream-like interface for that.
Similar short-cuts to DefaultMessenger() are added in Message package.
ViewerTest has been updated to send messages to Message::DefaultMessenger()
instead of direct output to std::cout/std::cerr.
Off-topic: spelling error (duplicate "and") is corrected in two places
Added test bugs fclasses bug31189
Before the patch, if the values of the isReversedX/Y/Z variables were set to false, then the WorldView matrix did not change and local transformation was not applied, which caused errors.
In order to correctly set the local transformation in case the text does not have its own attach point, the local transformation is set in OpenGl_Text, and the ModelWorld matrix is changed in OpenGl_Flipper, instead of the WorldView matrix. In this case, local transformation will always be applied.
bugs/vis/bug31193: test case added
Graphic3d_CullingTool::IsCulled() has been extended with theIsInside argument for full inclusion test.
Graphic3d_Layer::UpdateCulling() now avoids frustum culling tests for BVH children for parent nodes completely included into frustum.
Graphic3d_CullingTool::SetViewVolume() has been extended by optional model-world matrix.
A special mode for the selecting by polygon is added to select only completely overlapping objects.
In order to track the sensitives that were included completely by defined polygon, the boundary points of the polygonal frustrum are stored in the variable myBoundaryPoints.
If an sensitive intersects with at least one of the frustrums from myFrustums, then checking whether this object intersects with borders using the isIntersectBoundary method; if not, then the sensitive were included completely by defined polygon.
Because the polygon can be concave, then to check the sensitive were included completely by defined polygon, it is not enough to check of all its points, it is necessary that the edges of the sensitive do not intersect polygonal frustrum. To do this, for polygonal selection, a call to the Overlaps method for a point was replaced by a call to a segment where necessary.
bugs/vis/bug31440: test case added
OpenGl_Element now provide methods ::UpdateMemStats() and ::UpdateDrawStats()
for unified request of statistics used by OpenGl_FrameStats instead of direct handling of OpenGl_PrimitiveArray.

BRepFeat_Form.cxx: methods IsDeleted, Modified, Generated are corrected
BRepTest_FeatureCommands.cxx: history treatment is added in methods DEFIN and PERF
bugs/modalg_7/bug31469: test case added
Eliminate numerical instability by ensuring that the tolerance of intersection entities is slightly grater than the actual distance to the shapes creating the entity.
BRepMesh: Add new mesh parameter *AllowQualityDecrease* which affects the criteria used for checking of the consistency of the existing mesh to new meshing parameters.
So if set to true it will force the meshing of the shape if current deflection strongly vary from the new one, no matter in which side.
BRepTools::Clean: Keep triangulation on non-geometric shapes (faces with no surface or edges with no curves).

For small edges fully covered by tolerances of vertices BSpline periodic curves are converted to not periodic BSpline curves by cutting segment before writing.
In the class TopoDSToStep_MakeStepEdge permute of edge vertices for closed curves was added for the case when the range obtained from the vertex projection contradicts the edge range in order to avoid computation of the invalid edge range after reading.
Second test script for bug 0031301
Changes made for #31233 are reverted.
Correction in the ShapeFix_ComposeShell:

Modified test cases; added test for related issue: bugs step bug31301
In constructor of Geom_RectangularTrimmedSurface, skip check if an offset surface has insufficient continuity. The reason is that this surface has already passed the check once created. So, here we must not apply more strict check than that first time.
Prs3d_Drawer, AIS_Shape, AIS_InteractiveContext - removed properties HLRDeviationCoefficient() and HLRAngle().
Prs3d_Drawer::HLRAngle() is kept as alias to Prs3d_Drawer::DeviationAngle() with deprecated flag.
Prs3d_Drawer::DeviationAngle() default value is changed from 12 to 20 degrees
to match Prs3d_Drawer::HLRAngle() which has been previously used in majority of cases.
Removed unused property HLRBRep_PolyAlgo::Angle().

PrsMgr_PresentableObject::computeHLR().
Dummy implementations of previously declared methods have been removed
from AIS classes not implementng HLR presentation.

instead of handling OpenGl_PrimitiveArray specifically
for collecting Graphic3d_FrameStatsCounter_EstimatedBytesGeom counter.
OpenGl_PrimitiveArray and OpenGl_Text implement new interface.
- 'Search Qt4' is renamed into 'Search Qt'. Configuration uses Qt5 from now. For Qt4 use CMake configuration.
- 'Build Inspector' check box is added. It causes 'tools' toolkits compilation. Activates automatically 'Search Qt' control.
- Many Tcl procedures are extended with additional parameter to giving a directory of processed toolkits. The default directory is 'src', inspector directory is 'tools'. This way is similar Inspector compilation implemented in Cmake build procedure.
- Dependency libraries in DEBUG are stored in __TKDEP_DEBUG__. Qt requires it as names of debug and release libraries are different.
A case of reading of a very small value was skipped, for example: 2.1219957909652723e-314.
Fixed in XmlMDataStd_RealArrayDriver.cxx and XmlMDataStd_RealListDriver.cxx

Changes:
- in StepData_StepReaderData::ReadEntity, make sure that entity handle is not null before calling IsKind() of it.
- in StepData_StepReaderData::SetEntityNumbers, do not invert the sign of entity number of referenced parameter if the second pass is not required. Otherwise, the number -1 (obviously invalid) becomes 1 (invalid, but not obviously) without further correction of it.
- in StepData_UndefinedEntity::ReadRecord, consider the case when the entity number is positive but refers to non-existing entity. In this case literal value will be used instead of null entity for the problematic parameter.
"Range" parameter of point light sources (positional and spot) concidering in PBR has been added.

# OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting.
On Windows, the easiest way to install third-party libraries is to download archive with pre-built binaries from https://opencascade.com/content/3rd-party-components.
On Linux and OS X, it is recommended to use the version installed in the system natively.
@section dev_guides__building_3rdparty_win_1 Windows
This document presents guidelines for building third-party products used by Open CASCADE Technology (OCCT) and samples on Windows platform. It is assumed that you are already familiar with MS Visual Studio / Visual C++.
You need to use the same version of MS Visual Studio for building all third-party products and OCCT itself, in order to receive a consistent set of run-time binaries.
The links for downloading the third-party products are available at https://opencascade.com/content/3rd-party-components.
There are two types of third-party products used by OCCT:
* Mandatory products:
* Tcl/Tk 8.5 -- 8.6;
* FreeType 2.4.10 -- 2.5.3.
* Optional products:
* TBB 3.x -- 4.x;
* FreeImage 3.14.1 -- 3.16.0;
* VTK 6.1.0.
It is recommended to create a separate new folder on your workstation, where you will unpack the downloaded archives of the third-party products, and where you will build these products (for example, *c:\\occ3rdparty*).
Further in this document, this folder is referred to as *3rdparty*.
* Edit source file *tclMain.c* (located in folder *generic*) commenting out forward declaration of function *isatty()*.
4. In the command prompt, run *buildall.vc.bat*
You might need to run this script twice to have *tclsh* executable installed; check subfolder *bin* of specified installation path to verify this.
5. For convenience of use, we recommend making a copy of *tclsh* executable created in subfolder *bin* of *INSTALLDIR* and named with Tcl version number suffix, as *tclsh.exe* (with no suffix)
> cd D:\OCCT\3rdparty\tcltk-86-32\bin
> cp tclsh86.exe tclsh.exe
**Installation from sources: Tk**
Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
Apply the same steps as described for building Tcl above, with the same INSTALLDIR.
Note that Tk produces its own executable, called *wish*.
You might need to edit default value of *TCLDIR* variable defined in *buildall.vc.bat* (should be not necessary if you unpack both Tcl and Tk sources in the same folder).
FreeType is required for text display in a 3D viewer. You can download its sources from https://sourceforge.net/projects/freetype/files/
### The building procedure
1. Unpack the downloaded archive of FreeType product into the *3rdparty* folder. As a result, you will get a folder named, for example, *3rdparty\\freetype-2.4.10*. Further in this document, this folder is referred to as *freetype*.
2. Open the solution file *freetype\\builds\\win32\\vc20xx\\freetype.sln* in Visual Studio. Here *vc20xx* stands for your version of Visual Studio.
3. Select the configuration to build: either Debug or Release.
4. Build the *freetype* project.
As a result, you will get a freetype import library (.lib) in the *freetype\\obj\\win32\\vc20xx* folder.
5. If you build FreeType for a 64 bit platform, select in the main menu **Build - Configuration Manager** and add *x64* platform to the solution configuration by copying the settings from Win32 platform:
in line 255, uncomment the definition of macro *FT_EXPORT* and change it as follows:
#define FT_EXPORT(x) __declspec(dllexport) x
8. Build the *freetype* project.
As a result, you will obtain the files of the import library (.lib) and the dynamic library (.dll) in folders <i>freetype \\objs\\release</i> or <i>\\objs\\debug </i>.
If you build for a 64 bit platform, follow step 5 of the procedure.
To facilitate the use of FreeType libraries in OCCT with minimal adjustment of build procedures, it is recommended to copy the include files and libraries of FreeType into a separate folder, named according to the pattern: *freetype-compiler-bitness-building mode*, where:
* **compiler** is *vc8* or *vc9* or *vc10* or *vc11*;
* **bitness** is *32* or *64*;
* **building mode** is *opt* (for Release) or *deb* (for Debug).
The *include* subfolder should be copied as is, while libraries should be renamed to *freetype.lib* and *freetype.dll* (suffixes removed) and placed to subdirectories *lib *and *bin*, respectively. If the Debug configuration is built, the Debug libraries should be put into subdirectories *libd* and *bind*.
- Choose *Win32* if you are building for a 32 bit platform.
- Choose *x64* if you are building for a 64 bit platform.
5. Start the building process.
As a result, you should have the library files of FreeImage product in *freeimage\\Dist* folder (*FreeImage.dll* and *FreeImage.lib*) and in *freeimage\\Wrapper\\FreeImagePlus\\dist* folder (*FreeImagePlus.dll* and *FreeImagePlus.lib*).
VTK is an open-source, freely available software system for 3D computer graphics, image processing and visualization. VTK Integration Services component provides adaptation functionality for visualization of OCCT topological shapes by means of VTK library.
### The building procedure:
1. Download the necessary archive from https://www.vtk.org/VTK/resources/software.html and unpack it into *3rdparty* folder.
As a result, you will get a folder named, for example, <i>3rdparty\VTK-6.1.0.</i>
Further in this document, this folder is referred to as *VTK*.
2. Use CMake to generate VS projects for building the library:
- Start CMake-GUI and select VTK folder as source path, and the folder of your choice for VS project and intermediate build data.
- Click **Configure**.
- Select the VS version to be used from the ones you have installed (we recommend using VS 2010) and the architecture (32 or 64-bit).
- Generate VS projects with default CMake options. The open solution *VTK.sln* will be generated in the build folder.
3. Build project VTK in Release mode.
@section build_3rdparty_linux Linux
This document presents additional guidelines for building third-party
products used by Open CASCADE Technology and samples on Linux platform.
The links for downloading the third-party products are available on the web site at
For a 64 bit platform also add <i>--enable-64bit</i> option to the command line.
3. If the *configure* command has finished successfully, start the building process:
make
4. If the building has finished successfully, start the installation of Tk. All binary and service files of the product will be copied to the directory defined by *TK_INSTALL_DIR* (usually it is TCL_INSTALL_DIR)

@subsection build_occt_genproj Building with Genproj tool
This page describes steps to build OCCT libraries from a complete source archive on Windows with <b>MS Visual C++</b> using projects generated by **genproj** tool.
It is an alternative to use of CMake build system (see @ref build_occt_win_cmake).
**genproj** is a legacy tool (originated from command "wgenproj" in WOK) for generation of Visual Studio, Code.Blocks, and XCode project files used for building Open CASCADE Technology.
These project files are placed inside OCCT directory (in *adm* subfolder) and use relative paths, thus can be moved together with sources.
The project files included in official distribution of OCCT are generated by this tool.
If you have official distribution with project files included, you can use them directly without a need to call **genproj**.
Before building OCCT, make sure to have all the required third-party libraries installed.
The easiest way to install third-party libraries is to download archive with pre-built binaries, corresponding to version of Visual Studio you are using, from https://opencascade.com/content/3rd-party-components.
You can also build third-party libraries from their sources, see @ref build_upgrade_building_3rdparty for instructions.
@subsubsection build_msvc_conf Configuration
If you have Visual Studio projects already available (pre-installed or generated), you can edit file *custom.bat* manually to adjust the environment:

| VCVER | Visual Studio version | Windows Platform | Binaries folder name |
Launch **genproj** to update content of *inc* folder and generate project files after changes in OCCT code affecting layout or composition of source files.
@note To use **genproj** and **genconf** tools you need to have Tcl installed and accessible by PATH.
If Tcl is not found, the tool may prompt you to enter the path to directory where Tcl can be found.

@subsection build_occt_macos_xcode Building with Xcode
This file describes steps to build OCCT libraries from sources on Mac OS X with **Xcode** projects, generated by OCCT legacy tool **genproj**.
<h2>Configuration</h2>
Before building it is necessary to set up build environment.
The environment is defined in the file *custom.sh* which can be edited directly:
* Add paths to includes of used third-party libraries in variable *CSF_OPT_INC* (use colon ":" as path separator).
* Add paths to their binary libraries in variable *CSF_OPT_LIB64*.
* Set variable *SHORTCUT_HEADERS* to specify a method for population of folder *inc* by header files. Supported methods are:
* *Copy* - headers will be copied from *src*;
* *ShortCut* - short-cut header files will be created, redirecting to same-named header located in *src*;
* "HardLink* - hard links to headers located in *src* will be created.
* For optional third-party libraries, set corresponding environment variable <i>HAVE_<LIBRARY_NAME></i> to either *false*, e.g.:
~~~~~
export HAVE_GL2PS=false
~~~~~
Alternatively, or when *custom.sh* does not exist, you can launch *genconf.sh* to configure environment interactively:
@figure{/build/build_occt/images/genconf_osx.png}
Click "Save" to store the specified configuration in *custom.sh* file.
<h2>Projects generation</h2>
Launch **genproj** tool to update content of *inc* folder and generate project files after changes in OCCT code affecting layout or composition of source files.
@note To use **genproj** and **genconf** tools you need to have Tcl installed and accessible by PATH.
For instance, in Terminal application:
~~~~~
$ cd /dev/OCCT/opencascade-7.0.0
$ ./genproj
~~~~~
<h2>Building</h2>
To start **Xcode**, launch script *xcode.sh*.
To build a certain toolkit, select it in **Scheme** drop-down list in Xcode toolbar, press **Product** in the menu and click **Build** button.
To build the entire OCCT:
* Create a new empty project (select **File -> New -> Project -> Empty project** in the menu; input the project name, e.g. *OCCT*; then click **Next** and **Create**).
* Drag and drop the *OCCT* folder in the created *OCCT* project in the Project navigator.
* Select **File -> New -> Target -> Aggregate** in the menu.
* Enter the project name (e.g. *OCCT*) and click **Finish**. The **Build Phases** tab will open.
* Click "+" button to add the necessary toolkits to the target project. It is possible to select all toolkits by pressing **Command+A** combination.
<h2>Launching DRAW</h2>
To start *DRAWEXE*, which has been built with Xcode on Mac OS X, perform the following steps:
1.Open Terminal application
2.Enter <i>\<OCCT_ROOT_DIR\></i>:
~~~~~
cd \<OCCT_ROOT_DIR\>
