Decomposition of Ambient, Diffuse, Specular and Emissive properties has been eliminated within *Graphic3d_MaterialAspect* definition,
so that following methods of *Graphic3d_MaterialAspect* class have been removed:
SetReflectionMode(), SetReflectionModeOn(), Ambient(), Diffuse(), Emissive(), Specular(), SetAmbient(), SetDiffuse(), SetSpecular(), SetEmissive().
Graphic3d_NOM_NEON_GNC non-physical material definition has been corrected
and define WHITE emission color coefficient instead of YELLOW.
Added method Graphic3d_ClipPlane::SetCappingColor() for more straight-forward modification of Capping color in case of non-physical material.
Prs3d_ShadingAspect::Color() has been fixed to return InteriorColor instead of material color coefficient in case of non-physical material.

Graphic3d_Text is a new class for parameters necessary to fill OpenGl_Text. All parameters of Graphic3d_Group::Text() are moved into this class.
OpenGl_TextParam is removed, these fields were moved into Graphic3d_Text.
OpenGl_Text constructors/Init with OpenGl_TextParam parameter were removed. Constructor with Graphic3d_Text should be used instead of it.
Using OpenGl_Text Init() with OpenGl_TextParam should be now replaced on two cases. The first case is setting values into Graphic3d_Text and the second case is calling Reset() after. As example, look at modification in OpenGl_FrameStatsPrs.
SelectBasics_EntityOwner has been merged into SelectMgr_EntityOwner.
Unused property SelectMgr_EntityOwner::ResetLocation() has been removed.
SelectBasics package has been moved from TKService to TKV3d.
SelectBasics_SensitiveEntity has been merged into Select3D_SensitiveEntity.
Removed redundant proxy class Prs3d_Presentation - Graphic3d_Structure now should be used directly.
Removed auxiliary class PrsMgr_ModedPresentation holding Structure and Display Mode index (field has been moved to Structure itself),
so that PrsMgr_Presentations (AIS_InteractiveObject::Presentations()) now holds Structures directly.
PrsMgr_Prs proxy class has been removed, and PrsMgr_Presentation now inherits Graphic3d_Structure.
Graphic3d_Structure, maps declarations have been corrected to use class instead of void*, which allowed to avoid redundant casts.
Several methods have been also modified to avoid creating Handle from this pointer.
AIS package headers have been cleaned up from forward declaration of Prs3d_Presentation class.
Fixed dereference of destroyed presentations within connected and HLR computed objects:
- AIS_InteractiveContext::Disconnect() now erases connected presentation.

- fix inaccessibility of PrsMgr_Presentation methods
Removed excess mechanism for invalidating presentations AIS_InteractiveObject::myRecomputeEveryPrs.
PrsMgr_PresentableObject::Update() has been deprecated and replaced by PrsMgr_PresentableObject::UpdatePresentations()

and Graphic3d_AspectText3d have been merged into new class Graphic3d_Aspects.
The old classes are preserved as dummy sub-classes of Graphic3d_Aspects
preserving different per-aspect defaults.
Methods IsGroupPrimitivesAspectSet(), GroupPrimitivesAspect(), FillAreaAspect(),
LineAspect() and MarkerAspect() have been removed from Graphic3d_Group.
Instead, a new method Graphic3d_Group::ReplaceAspects() has been introduced
for replacing existing group aspects.
AIS_Shape now uses new method AIS_InteractiveObject::replaceAspects()
for updating computed groups with new aspects without presentation recomputation
in places where SynchronizeAspects() is not applicable.

and OpenGl_AspectText have been merged into new class OpenGl_Aspects.
ViewerTest::parseColor() - fix uninitialized alpha component.
Graphic3d_AspectText3d/Prs3d_TextAspect - removed unused properties Space, ExpansionFactor, Angle.
Remove getters Values() deprecated since OCCT 7.1.0.
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.
OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).
vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.
ViewerTest::ParseColor() now parses RGBA color.
Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
Two new functionalities have been added in BRepFilletAPI_MakeChamfer:
- constant throat (the section of chamfer is isosceles triangle, its height is constant in all sections - this is the "throat" of the weld);
- constant throat with penetration(the section of chamfer is right-angled triangle, the first of two surfaces (where is the top of the chamfer) is virtually moved inside the solid by offset operation, the apex of the section is on the intersection curve between moved surface and second surface, right angle is at the top of the chamfer, the length of the leg from apex to top is constant - this is the "throat" of the weld).
- New abstract classes BlendFunc_GenChamfer and BlendFunc_GenChamfInv have been added;
- Class BlendFunc_Chamfer is now descended from BlendFunc_GenChamfer, class BlendFunc_ChamfInv is now descended from BlendFunc_GenChamfInv.
- New class BlendFunc_ConstThroat is descended from BlendFunc_GenChamfer, new class BlendFund_ConstThroatInv is descended from BlendFunc_GenChamfInv.

- Class ChFi3d_ChBuilder has now mode of chamfer that can be ClassicChamfer, ConstThroatChamfer and ConstThroatWithPenetrationChamfer.
- Two new DRAW Test Harness commands "chamf_throat" ant "chamf_throat_with_penetration" have been added for the second mode of ChBuilder.
- The interface of DRAW Test Harness command "chamf" changed for symmetric case.
1. Check whether the mesh satisfies the required angular deflection has been amended. Namely normals (to the surface) in the ends of any not "frontier" link are made collinear (with the given angular tolerance).
2. New parameters AngleInterior and DeflectionInterior have been added in IMeshTools_Parameters structure.
3. In case of thin long faces with internal edges, add points of internal edges to control parameters using grabParamsOfInternalEdges() in order to avoid aberrations on its ends. Disable addition of parameters from boundary edges in case of BSpline surface. Deviation can be controlled through the deflection parameter.
4. Grab parameters from edges in case if there is just a single interval on BSpline surface along U and V direction.
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
Correction in upgrade guide.
Replacing usage of BRepAlgo_DSAccess with usage of modern Boolean operations algorithms in BRepFill_Draft.
Removing BRepAlgo_BooleanOperations and BRepAlgo_DSAccess classes.
The following classes have been removed as unused:
* BRepAlgo_DataMapOfShapeBoolean
* BRepAlgo_DataMapOfShapeInterference
* BRepAlgo_EdgeConnector
* BRepAlgo_SequenceOfSequenceOfInteger
Extended SelectBasics_PickResult structure by myObjPickedPnt field, which contained the value of the 3d point on the selected object.
Changed all Overlaps methods. Parameter theDepth replaced on object of the structure SelectBasics_PickResult. This approach will be able to add new fields to SelectBasics_PickResult structure without big changes in modules which contained Overlaps method.
Methods GeomConvert::ConcatG1, GeomConvert::ConcatC1, Geom2dConvert::ConcatG1, Geom2dConvert::ConcatC1 are corrected to prevent exceeding maximum degree of BSpline curve in case of closed contour.
Deprecated functionality related to Local Context has been removed.
The following classes and types have been removed:
AIS_LocalContext, AIS_DataMapOfILC, AIS_LocalStatus, SelectMgr_SequenceOfSelector, SelectMgr_DataMapOfObjectSelectors.
Value AIS_DS_Temporary has been removed from enumeration AIS_DisplayStatus.
The following methods related to Local Context have been removed from AIS_InteractiveContext:
::HasOpenedContext(), ::HighestIndex(), ::LocalContext(),
::LocalSelector(), ::OpenLocalContext(), ::CloseLocalContext(),
::IndexOfCurrentLocal(), ::CloseAllContexts(), ::ResetOriginalState(),
::ClearLocalContext(), ::UseDisplayedObjects(), ::NotUseDisplayedObjects(),
::SetShapeDecomposition(), ::SetTemporaryAttributes(),
::ActivateStandardMode(), ::DeactivateStandardMode(), ::KeepTemporary(),
::SubIntensityOn(), ::SubIntensityOff(),
::ActivatedStandardModes(), ::IsInLocal()
and ::AddOrRemoveSelected() taking TopoDS_Shape.
The methods AIS_InteractiveContext::Display() and ::Load()
taking argument theToAllowDecomposition have been marked as deprecated;
the new methods without this unused argument should be used instead.
AIS_InteractiveContext::DisplayedObjects() - removed argument theOnlyFromNeutral.
SelectMgr_SelectionManager has been simplified so that now it support only single Viewer Selector.
The argument -local has been removed from Draw Harness commands vselmode, vremove, vdisplay, vdisplayall, verase.
Implementation of the method for simplification of the result of Boolean Operation on the API level.
The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method.
The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm.
Draw command "bsimplify" has been added to control the simplification options.
Documentation for new functionality and draw commands controlling the options of Boolean operations.
Test cases for the new functionality.
Side-effect change:
The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool.
Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command).
Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.
1. Extrema algorithm calls Curve-surface intersector. This intersector returns flag about infinite solution (in spite of extrema's returning not-parallel status correctly - axes of considered cylinder and circle are not parallel). In this case, attempt of obtaining number of intersection points leads to exception.
So, the fix adds check of infinite solution after the intersection algorithm.
2. The methods IsDone(), IsParallel(), NbExt(), SquareDistance() and Points() (of Extrema_* classes) have been corrected to make them consistent to the documentation.
3. Revision of some Extrema_* classes has been made in order to avoid places with uninitialized variables.
4. Currently Extrema does not store any points in case when the arguments are parallel. It stores the distance only.
5. Some cases on Extrema-algo have been moved from "fclasses"-group to "modalg"-group.
Substitution of degenerated edges by their copies is implemented to make edges not shared
in BRepPrimAPI_MakeRevol::Build().
Method BRepPrimAPI_MakeRevol::Generated(...) is changed in order to use history of substitutions.
Test case is added.
Information on replacement of CDM_MessageDriver by Message_Messenger is added in the upgrade guide.
This replacement is recorded as rename in upgrade.dat
The API classes in the package BRepAlgo providing access to old Boolean operations (Fuse, Common, Cut, Section) are marked as deprecated.
Corresponding classes from the package BRepAlgoAPI should be used instead.
When checking if the split edge is oriented as the original one (BOPTools_AlgoTools::IsSplitToReverse()) the tangent vectors should be computed for both edges at the same point. This point is taken on the split edge and projected on the original edge.
The fix is intended to ensuring that the reference point will be taken inside the valid range of the split edge (i.e. not covered by the tolerance spheres of its bounding vertices) and the projection of this point on the original edge will be successful. Moreover, several sampling points are now taken on the split edge and processed until first valid point is found.
If requested (by a not null pointer) all *BOPTools_AlgoTools::IsSplitToReverse()* methods are now return the error status of the check. Before using the returned flag, the calling program should check this error status. For successful check the error status should be equal to zero.
New warning *BOPAlgo_AlertUnableToOrientTheShape* is now returned in the algorithms in Boolean component in case the check for correct shape orientation failed.
Test case for the issue.
- BUILD_SAMPLES_MFC instead of BUILD_MODULE_MfcSample
- BUILD_SAMPLES_QT instead of BUILD_MODULE_QtSample
- sub-folder "mfc" of Samples folder in VStudio for mfc samples
- qt processing of *.ts resource files is corrected to avoid excessive projects creation under Samples folder in VStudio
Boolean Operation - avoid creation of INTERNAL solid from unclassified faces in Solid Builder algorithm.
Instead warn the user that some of the faces have been unclassified and not used for solids creation.
Adjustment of the test cases.
Test cases for the issue.
All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated.
Common macro Standard_EXPORT is used in all places where it is necessary.
New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility).
To allow building OCCT in static mode on Windows after these changes:
- Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx
- In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions
- Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index
- Unused class Quantity_Convert is removed (it had static field accessed by inline method)
- Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash
- Some C++ files producing no object code are removed
- In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols
The following unused declarations have been removed:
Aspect_TypeOfPrimitive, Aspect_TypeOfLayer, Aspect_TypeOfEdge,
Aspect_TypeOfDrawMode, Aspect_TypeOfConstraint,
Aspect_DriverDefinitionError, Aspect_BadAccess.
Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(),
which is set to Graphic3d_TOSM_DEFAULT by default.
The new API allows assigning Shading Model to specific Primitive Array groups
instead of entire Viewer, which was the only possibility before.
Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value
meaining that Shading Model defined as default for the Viewer should be used.
Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT.
Documentation of Shading Models has been improved by more details.
V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel
avoiding duplicated definitions and confusion.
Old values has been left for compatibility with old code and can be marked deprecated in future.
Draw Harness command vaspects has been extended by new argument -setShadingModel
for testing Shading Models assigned to entire objects.
OpenGl_SetOfShaderPrograms now holds an array of Shading Models.
OpenGl_ShaderManager interface has been modified and now requires enumeration as input
in several places where Boolean flags have been used previously
(methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()).
OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT
to simplify indication of primitive groups with undefined Fill Area aspects,
and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers.
AIS_Manipulator::Axis::Compute() - added missing initialization of Fill Area aspects (leading to undefined behavior).
Now, bounded IntPatch_Points are found in case when starting points are used in intersection algorithm. Before the fix, these points were not looked for (even).
The usage of *BRepAlgo_Section* has been replaced with the usage of *BRepAlgoAPI_Section* in *BRepProj_Projection* algorithm.
The TODO statements have been removed from the failing test case in the "prj" grid as they are working correctly now.
The following changes have been made to improve the performance *BRepAlgoAPI_Section*:
1. Revision of the *IntPolyh_Intersection* class to avoid repeated calculation of the deflection of the same triangulation.
2. Small revision of the Edge/Face intersection algorithm to perform Extrema computation on the whole intersection range of the edge instead of discrete ranges.
3. Implementation of the extrema computation for the Circle and Sphere.
4. Correct computation of the parameter of the point on the Circle.
