A new Shaded presentation flag configured through Datum aspect (NOT as usual Display Mode).
Creation of auxiliary Axis/Point/Plane presentations in Trihedron presentation is removed.
'vtrihedron' DRAW command to change parameters of trihedron is extended to cover whole functionality of AIS_Trihedron.
The following classes are redesignede:
AIS_Trihedron,
Prs3d_DatumAspect.
The followin enumermations are created to manage properties of trihedron:
Prs3d_DatumAttribute,
Prs3d/Prs3d_DatumAxes,
Prs3d_DatumMode
The following improvements have been made:
1. Linking edges to triangles while creating the edges.
2. Replacing the array of couples of intersecting triangles with the list to avoid unnecessary allocations of memory.
3. Using the algorithm of unbalanced binary tree when looking for pairs of interfering triangles.
4. Building bounding boxes for the triangles only once and then reusing it.
5. Making the simple methods of the IntPolyh_Point, IntPolyh_Edge, IntPolyh_Triangle, IntPolyh_Couple classes inline.
6. The following methods of the *IntPolyh_Triangle* class have been removed as unused:
- *CheckCommonEdge*
- *SetEdgeandOrientation*
- *MultipleMiddleRefinement2*.
7. The method *IntPolyh_Triangle::TriangleDeflection* has been replaced with the *IntPolyh_Triangle::ComputeDeflection*.
8. The following methods of the *IntPolyh_MaillageAffinage* class have been removed as unused:
- *LinkEdges2Triangles*;
- *TriangleEdgeContact2*;
- *StartingPointsResearch2*;
- *NextStartingPointsResearch2*;
- *TriangleComparePSP*;
- *StartPointsCalcul*.
1. Clearance of fields of class has been added to the method BRepFill_PipeShell::Prepare().
2. Calculation of error on surfaces has been corrected in the method GeomFill_Sweep::BuildKPart().
3. New Draw command "errorsweep" has been added to check the error reached on the surfaces built by BRepOffsetAPI_MakePipeShell algorithm.
1. Bug fix in reading old persistent data using FSD_File storage driver
2. Persistence compatible with legacy format was restored for shapes
a. Implemented a storage read / write wrapper for legacy persistence
b. Added DRAW commands to read / write files in legacy format
c. Added test cases for reading / writing operations with checking number of sub-shapes and physical properties
d. Updated related sections of the development guide
- The option SafeInputMode has been added in the class ShapeUpgrade_UnifySameDomain. If it is set then the input shape is protected against modifications of any aspects of its sub-shapes. Default value is true.
- The option "-nosafe" has been added in draw command "unifysamedom". If it is not set the algorithm is run with SafeInputMode switched off.
- New method BRepLib::FindValidRange() has been added. It computes the range of the edge not covered by boundary vertices.
- The algorithm of calculation of valid intersection range in the class IntTools_ShrunkRange has been corrected to use the new method.
- The method BOPTools_AlgoTools::MakeSplitEdge() has been improved to protect against errors in the case of reversed orientation of the input edge.
- Two new Draw commands have been added:
validrange - it calls the new method BRepLib::FindValidRange().
tolsphere - it shows tolerances of vertices by drawing a sphere around each vertex of the shape.
- The test cases "offset shape_type_i_c YE1,YE2" became better. The scripts have been corrected to reflect the new state.
OSD_Environment::Value() now uses GetEnvironmentVariableW() instead of _wgetenv()
which might provide outdated variable value cached by C runtime library.
Macro THIRDPARTY_PRODUCT was updated to create separate variable which contains all used 3rdparty dll/library directories (used custom.bat/sh files).
Name of Tcl/Tk libraries for search were updated.
~OSD_Thread(), OSD_Thread::SetFunction() and OSD_Thread::Run()
now detach old thread also on platforms using pthreads.
OSD_Thread::Wait() now closes thread handle after joining.
1. Re-orienting the shell before making solid from it (MakeShell in BOPAlgo_ShellSplitter);
2. The implementation of the BOPTools_AlgoTools::IsSplitToReverse() method has been changed to
make the usage of the Hatcher for looking for the point in the face default.
3. Test cases for the issue.
1) BRepLib::UpdateTolerances(..) & BRepLib::SameParameter(..) functions now support non-mutable input feature. reshaper is used to store modified copies of subshapes of original (input) shape(s) as substitutions.
2) IsNewShape(..) method has been added to BRepTools_ReShape to check if the given shape has been recorded as a value
Use Quantity_ColorRGBA instead Quantity_Color in XCAFDoc_Color attribute
Add methods to color tool for processing RGBA
Update Color driver
Update Draw commands
1. Modification in static function IntersectionWithAnArc of IntPatch_ImpImpIntersection :
small offset <du> was hardcoded as 1.e-9, now it is adapted to parametric step.
2. Removal of duplicated points of IntPatch_WLine is corrected.
OpenGl_AspectMarker::Resources::BuildSprites(), fixed uninitialized theMarkerSize
in case if aspect has been already initialized for specified marker type.
Draw Harness command vaspects has been extended with new options -setMarkerType and -setMarkerSize.
The improvement is concluded in replacement of calls to gp_Dir2d(1,0) with calls to gp_Dir2d(void).
Thus we avoid sqrt() that is called from within gp_Dir2d(double,double). The same is with direction in 3D space.
The Face/Face intersection procedure has been changed in Boolean Operations algorithm.
Previously, the intersection tolerance for all section curves between pair of faces has been calculated
as the maximal tolerance among all curves. Now, each curve has its own valid tolerance calculated
as the maximal deviation of the 3D curve from its 2D curves on faces or surfaces in case there are no 2D curves.
Thus, such methods of IntTools_FaceFace algorithm as TolReached3d(), TolReal() and TolReached2d() have been removed.
Now the tolerances of the curve can be obtained from the curve itself (IntTools_Curve - result of intersection):
- IntTools_Curve::Tolerance() - returns the valid tolerance for the curve;
- IntTools_Curve::TangentialTolerance() - returns the tangential tolerance, which depends on the size of the common
between faces. Currently, this tolerance is computed for Plane/Plane cases only. For other case, the value
of the tangential tolerance is the maximal tolerance of faces.
2D intersection tolerance (IntTools_FaceFace::TolReached2d()) has been completely removed from the algorithm as unused.
1. The packages *QANewModTopOpe*, *QANewBRepNaming* and *QANewDBRepNaming* have been removed as containing obsolete features.
The corresponding QA commands (such as OCC252, OCC307 and OCC294) and test cases have also been removed.
2. The QA command buc60609 has been removed. The corresponding test case bugs/moddata_1/buc60609 has been rewritten using b2dclassify command.
Shell check has been improved to use well-known width-first search. It significantly reduces computation time on the big shells.
Test case has been added.
Minor correction in test case
1. The TestTopOpe* packages have been removed.
2. The commands *compare*, *issubshape* and *projponf* have been moved to BRepTest package.
3. The possibility to change the Extrema options has been added to projection algorithm (GeomAPI_ProjectPointOnSurf).
4. Documentation has been updated.
1. The CellsBuilder algorithm has been extended to work with multi-dimensional arguments.
It has become possible not only simulate Boolean expressions, but also perform non-supported
Boolean operations, like cutting face from solid, or fusing face with edge.
2. Test cases with multi-dimensional input shapes have been created.
3. Documentation has been updated.
1. Removal of the traces of the usage of old Boolean operations in BRepFeat package.
2. The DRAW commands *fubl* and *cubl* based on old Boolean operations have been removed.
The alternative for these commands are the commands *bfuseblend* and *bcutblend* respectively.
The last two commands are based on the modern Boolean operations.
3. The DRAW command *ksection* based on old Boolean operations has been removed.
The command *bsection* should be used as alternative.
Test cases which have been using the *ksection* command have been modified to use the *bsection* command.
4. The class QANewBRepNaming_BooleanOperation has been modified to use modern Boolean operations.
The class QANewBRepNaming_BooleanOperation has been removed as not used.
The class QANewBRepNaming_BooleanOperationFeat has been renamed to QANewBRepNaming_BooleanOperation as it has nothing to do with Feat algorithm.
The usage of the old Boolean operations (implemented in the class BRepAlgo_BooleanOperations) in the
BRepAlgo_NormalProjection algorithm has been replaced with the usage of new Boolean operations
(implemented in the class BRepAlgoAPI_BooleanOperations).
1. Using appropriate intersection tolerance for splitting the degenerated edges in Boolean operations (void BOPAlgo_PaveFiller::FillPaves()).
2. Avoid creation of the wires consisting of degenerated edges only (BOPAlgo_WireSplitter).
3. Test case bugs/moddata_2/bug469 has been corrected to obtain valid result of operation. TODO statements have been removed from the case.
The cause of the bug was computation of incorrect UVBounds in the method ShapeAnalysis::GetFaceUVBounds. In this patch the computation of a box for a 2D curve in the method ShapeAnalysis_Curve::FillBndBox() has been improved taking into account intervals of C2 continuity.
Also the fix makes little extension of bounds when making the new surface in ShapeUpgrade_FaceDivide::SplitSurface(), so that all p-curves were fully inside.
Test case for issue CR28553
- The methods "Modified" and "IsDeleted" have been added for history support in "ShapeUpgrade_UnifySameDomain" class.
- The new Draw commands "unifysamedommod" and "unifysamedomisdel" have been added.
- Adoption of other algorithms using this one to its new behavior.
Removing code duplication
Correcting regressions
Correcting remarks
The new method TopExp::MapShapesAndUniqueAncestors has been implemented, which excludes duplication of ancestors in the list items. The optional Boolean argument 'useOrientation' of this method points whether two same shapes with different orientation will be considered equal.
OCCT code has been inspected and MapShapesAndAncestors has been replaced with MapShapesAndUniqueAncestors where it is necessary.
Generation of 3D-steps shorter than 3D tolerance has been allowed in the fix to build Walking-line.
Now, 3D-step is limited by Precision::Confusion value.
1. The partition operation allows splitting an arbitrary number of shapes of an arbitrary dimension
by other arbitrary shapes. The algorithm has been implemented in the class BOPAlgo_Splitter.
The API operator Splitter has been implemented in the class BRepAlgoAPI_Splitter.
2. The draw commands for usage the new algorithm have been implemented - bsplit and bapisplit.
The commands are identical, but one uses the BOPAlgo_Splitter, the other uses BRepAlgoAPI_Splitter.
Both commands should be used after Pave Filler is filled.
3. Test cases for the new algorithm.
4. Documentation has been updated.
Small corrections.
1. The algorithm BOPAlgo_ShellSplitter has been improved for the cases with multi-connected edges
to produce as many shells as possible from the given input faces.
2. Building tool prism in BRepFeat_MakePrism has been changed in order to avoid self-intersections
in the cases when the limiting faces are intersecting.
3. Test cases for the issue.
4. Test cases boolean/bcut_complex/N9 and boolean/gdml_private/ZH3 are improvements.
5. Test cases boolean/volumemaker/C5 and boolean/volumemaker/C6 has been marked as BAD due to found problem in intersection algorithm.
The results in these cases obtained on the branch are better than on master, but still not complete.
Adjusting test case bugs/moddata_2/bug469 for its current behavior.
NCollection_Array1 now provides method Resize() for re-allocating array to new bounds.
Added Move Constructor and Move Assignment operator.
Added empty constructor defining array of zero size.
Poly_Triangulation, dropped duplicating fields myNbNodes and myNbTriangles.
Removed unused file Poly_Triangulation.lxx.
Use std::move within NCollection_Array1::operator=() [fix for 0028470]
1. Exception in intersection of two analytical faces has been fixed by adding a simple check on number of vertices
in the resulting analytical curve;
2. Projection of the Circle on the Cone now checks if the Circle's normal direction is parallel to the Cone direction.
If it is not, the different, more advanced, algorithm will be used for projection - ProjLib_ComputeApprox;
3. Intersection of the Edge with the Face (IntTools_EdgeFace algorithm) in QuickCoincidenceCheck mode has been fixed to
avoid the checking of the type of the intersection result if the coincidence check gives the positive result;
4. All common IN edges of the intersecting faces has been added for intersection with section edges to avoid self-intersection in the result;
5. Post treatment of the section edges in Boolean operations has been improved with the new stage which treats the possible
common zones, not detected by the intersection algorithm, between faces by intersecting each section edge with all faces,
not participated in its creation, and in case of coincidence putting it as IN edge into FaceInfo structure of the face.
The new function has been implemented for that - BOPAlgo_PaveFiller::PutSEInOtherFaces().
6. Checking for the SameDomain splits of faces in Boolean Operations has been modified to process the pairs of faces in
which both the section curves and common zones are present.
7. Adjustment of the test case boolean gdml_private ZH3 as improvement.
8. Test cases for the issue.
9. Test cases for the parent issue - 0026789.
While checking the SurfaceOfExtrusion on closeness (GeomLib::IsClosed())
it is necessary to take into account that the basis curve may be not trimmed.
Test case for the issue.
Looking for inverted edges among the neutral ones while checking the offset edges on validity (BRepOffset_MakeOffset_1::FindInvalidEdges).
Test cases for the issue.
The main idea of the fix is to forbid check if intersection curve lies in the some face (with input tolerance) if we have 2D-intersection curve on this face (we consider that necessary tolerance has been computed in intersection algorithm honestly). If we do not have 2D-curve on this face then we need check as before.
New algorithm is implemented in IntTools_Context::IsValidBlockForFaces(...) method.
------
src\Extrema\Extrema_GenExtPS.cxx
No principled changes have been made.
Virtual method Generated is redefined. Now it returns:
- chain of generated faces for sub-edge of a profile;
- chain of generated edges for sub-vertex of a profile;
- bunch of chains of generated edges for start or end vertex if it is degenerated section.
Correction according to the remarks.
Fix compiler's warnings and add 4 new test cases.
Correction of mistake.
Compilation warnings are gone.
Graphic3d_RenderingParams::RenderResolutionScale - added new option
defining scale factor for allocating off-screen rendering buffers
relative to native resolution of window buffer.
Scale factor can be below 1.0 (lower resolution) or higher (as analog of super sampling),
but can not be combined with MSAA settings.
Draw Harness command vrenderparams has been extended with option -rendScale
managing introduced option Graphic3d_RenderingParams::RenderResolutionScale.
vcaps has been extended with option -useWindowBuffer for managing
OpenGl_Caps::useSystemBuffer option.
vrepaint has been extended with option -immediate
for testing immediate layer redraw
OpenGl_View::blitBuffers() - eliminate compiler warning on Android
Existing OCCT path tracing engine used very simple additive material (BSDF) model, so it was possible to reproduce
behavior only of very basic materials such as metal, glass, or plastic. However, some important in CAD industry
materials like car paint or ceramic could not be modeled well. In this patch, OCCT BSDF was significantly improved
by replacing additive model with two-layered scattering model. Therefore, we have base diffuse, glossy, or transmissive
layer, covered by one glossy/specular coat. The layers themselves have no thickness; they can simply reflect light or
transmits it to the layer under it. Balancing different combinations of layer properties can produce a wide range of
different effects. At the same time, disabling the first (coat) layer allows to keep full compatibility with previously
supported scattering model. All new parameters are available via 'vbsdf' command.
Location of new sample for few material examples:
samples\tcl\pathtrace_materials.tcl
Fix shader compilation issue.
Fix test case sample_ball_alpha.
Shaders_PathtraceBase_fs.pxx - regenerate resource from origin
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
New method CheckFaceSelfIntersection has been added to BOPAlgo_CheckerSI: now self-intersection of each face is found as well as pairs of intersecting faces;
-method IntPatch_Intersection::Perform(S1,D1,TolArc,TolTang) is modified for more effective search of self-interasections in case of Surface Of Extrusion;
-method IntCurve_IntPolyPolyGen::Perform(C1,D1,TolConf,Tol,NbIter) is modified to detect segments of intersections.
Small correction.
Test cases are corrected.
Correction of compiler error
Fix of regressions
Names of shapes correction
1. For the support of the new configurations of the input shapes for the 3D offset algorithm
(shapes containing the faces with holes, which are growing during offset operation and
sometimes (depending on the offset value) even kill the faces themselves) the new function
*FindFacesInsideHoleWires* has been implemented. This new function looks for the splits of
the offset face located inside the new hole wire built from offset edges of the edges of the
hole wires of the original face. All found splits are simply removed.
2. Test cases for the issue.
Unit test and additional parsing rule for tests are added as well as a minor fix of the draw command for bug24164_2 unit test (in reference array it was impossible to set only one value).
Added the exception for the checking in issue 2269, when bad document is read.
It checks that there is no crash, but just an error message. If crash is appeared, this test will not skipped anyway.
Correction of test for bug2269 and parse.rules
1. The static method Standard_Real MinStep3D(...) in the class BOPTools_AlgoTools is
now checks if the computed 3D step is too big (relatively UV range of the faces)
for any of the faces.
2. The method PointInFace(...) of the class BOPTools_AlgoTools3D has been redesigned.
The new PointInFace(...) methods have been implemented to add possibility for looking the point
inside the face in necessary direction and distance from the edge of the face.
Note: old implementation is also functional.
3. Make methods for finding points near edges and computing normal directions on faces
return error status (0 in case of success).
4. Test case for the issue.
5. Test cases offset shape_type_i_c XJ2,XJ4,XJ5,XJ6 are improvements.
Removing useless file
1. The two new methods have been implemented:
a. BOPAlgo_Tools::EdgesToWires - allows creating planar wires from edges.
The input edges may be not shared, but the output wires will be sharing the coinciding vertices and edges.
It is possible to skip the sharing if the input edges are already shared by passing the corresponding flag into the method.
The input edges are expected to be planar, but the method does not check it. Thus, if the input edges are not planar, the output wires will also be not planar.
In general, the output wires will be non-manifold and may contain free vertices.
b. BOPAlgo_Tools::WiresToFaces - allows creating planar faces from the planar wires.
In general, the input wires are non-manifold and may be not closed, but should share the coinciding parts.
The wires located in the same plane and completely included into other wires will create holes in the faces built from bigger wires
These two methods combined allow building faces from set of edges randomly located in 3D space.
2. The DRAW command *edgestofaces* has been implemented.
3. The documentation has been updated with the new section in Modeling Algorithms - Topological Tools.
4. Test cases for the issue.
Added option ShapeFix_Solid::FixShellOrientationMode allowing to switch off analysis and fixing of orientations of shell(s) in solid.
Options FixVertexToleranceMode, FixShellOrientationMode, FixFaceOrientationMode are added to Shepe Processing resource file so that they can be manipulated.
Added new method Draw_Window::IsMapped() for checked window state.
Draw_Window using XLib now does not exit application on closing window.
The method Draw_Viewer::Select() (called by whatis command)
has been corrected so as not to enter the loop if no views are initialized.
The code of the methods BSplCLib::KnotForm and BSplCLib::MultForm has been made safe by giving up using of address of array item for iteration on the Array1. Also the checking for degenerated case has been added to prevent out of bounds exception.
Class DBRep_DrawableShape is changed to postpone generation of display data until the shape is actually displayed (for the first time).
Test perf draw bug28404 is added.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
Useless writes of intermediate shapes to hardcoded paths are removed in samples\mfc\standard\02_Modeling\src\ModelingDoc.cpp
Methods IGESBRep::WriteShape(), XSControl_Utils::WriteShape() are deleted; BRepTools::Write() can be used instead.
Method TopOpeBRepBuild_Tools::DumpMapOfShapeWithState() is moved to where it is used -- TopOpeBRepBuild_Builder1_1.cxx as static function (commented out).
Unused DRAW command OCC18612 is removed.
Upgrade Guide is corrected to avoid Doxygen warnings.
1. The smarter conditions for removing the invalid faces with inverted edges have been implemented
(BRepOffset_MakeOffset::RemoveInvalidSplitsByInvertedEdges).
2. Avoid removed (completely inside) edges in the filtering of invalid faces
(BRepOffset_MakeOffset::FilterInvalidFaces).
3. Test cases for the issue.
The patch fixes transformation persistence for various set of GCC compilers.
1) Optimized template-specialized operator /= for division (causes bugs)
of NCollection_Vec4 was replaced with non-specialized version.
2) NCollection_Vec4::xyz() is not used since compiler uses modifiable-reference
returning version, which invokes warning of possible strict-aliasing rules
violation and leads to incorrect behavior of the reference.
If the line is in the circle-plane completely (or parallel to the circle-plane) then extremas and intersections in 2D-space are looked for. These case are pure analytical and solutions will be found precisely.
Table of supported operating systems with versions is removed, in favor of more general statement with simple list of supported OS and architectures.
Outdated list of tested graphic cards has been dropped.
1) In Views menu the check button item "Extended view commands" has been added. Pressing on it shows/hides the set of buttons in the main window that allow manipulating of view zoom/pan/rotate by mouse.
2) New category of commands "Vector and measurement Commands" has been added. The commands in this category allow simple calculations using 2D and 3D vectors, such as cross and dot products, computation of distances of points to other objects, and other functions.
3) The new command "pickf" has been added in "DRAW Variables management" category. It allows extracting a picked with mouse face included in some shape as a new variable.
4) New commands "del" and "era" have been added in "DRAW Variables management" category. They allow deleting (destructing) or erasing (from view) variables matched by glob pattern.
5) Missing help for some commands like "don", "disp" and others has been added.
1. The methods PerformVZ, PerformEZ, PerformFZ and PerformZZ have been transferred from BOPAlgo_PaveFiller to BOPAlgo_CheckerSI class
to perform intersection of sub-shapes with solids only in self-intersection mode.
2. The checks for solids built from the same (shared) faces have been added into methods building the result of Boolean operations -
BOPAlgo_BOP::BuildRC() and BOPAlgo_BOP::BuildSolid().
3. Since the NonDestructive mode is now natively supported by the BOPAlgo_PaveFiller the methods providing the support of this mode by CheckerSI
(BOPAlgo_CheckerSI::PrepareCopy() and BOPAlgo_CheckerSI::PostTreatCopy()) are not needed and have been removed.
4. The pairs of sub-shapes with interfering bounding boxes are now sorted before real intersection to guarantee the constant order of
intersection of sub-shapes and produce more stable result. The class BOPDS_PassKey has been replaced with simpler class BOPDS_Pair.
5. The class BOPDS_SubIterator has been refactored.
6. Test cases for the issue.
7. Adjustment of the test case boolean volumemaker D2.
1. Earlier we could not put any IntPatch_Point to the intersection curve. The fix makes the algorithm of IntPatch_Points searching more precise. It is achieved by redetermination of earlier found vertices with help of minimization the distance between boundary of one intersection argument and another intersection argument (surface).
2. Additional check has been added, if IntPatch_Point adjusted to the domain boundary is true intersection point.
3. Method Contap_ArcFunction::Surface() has been added.
4. Method LastComputedPoint() has been added for IntPatch_ArcFunction and Contap_ArcFunction classes.
5. Correction in FindMaxDistance() method (see IntTools_FaceFace.cxx file) according to pure Golden-ratio minimization algorithm. Earlier this function worked wrong with small searching intervals.
6. Insignificant correction in math_BrentMinimum.cxx file (elimination of "defines").

For infinite objects Cone with semiangle > PI/2 - eps is replaced by SurfaceOfRevolution for eps < Precision::Confusion()
Tests cases are added
Small correction of shape names for issue CR28261_28266
1. There has been implemented calculation of all possible types of continuity for shared edges:
* G1 is set if tangential planes are the same for connected faces in each control points through the edge;
* C1 is set in addition to G1 conditions if derivatives, orthogonal to the edge on each face, are equal vectors;
* G2 is set in addition to G1 if the centers of principal curvatures are the same for connected faces in each control points through the edge;
* C2 is set in addition to C1 and G2 if directions of principal curvatures are equal;
* CN continuity is set only if both connected faces are based on elementary surfaces (the conditions for this case are similar to C2 continuity).
2. ShapeFix::EncodeRegularity() is merged into BRepLib::EncodeRegularity().
3. Implemented several test cases to check correct handling of regularity.
4. Fix incorrect usage of BRepLib::EncodeRegularity() in BRepBuilderAPI_Sewing.
5. Implement a method for calculation of regularity on the given list of edges.
6. Documentation updates
Fixed uninitialized fields in several classes.
Body of trivial methods have been moved to class definition (header file).
Ensure that non-primitive types are returned by reference, when possible.
Removed unused class Prs3d_PlaneSet.
Added compile-time checks (static_assert) in DEFINE_STANDARD_RTTI*(A,B) macros to check that A is actually the class being defined, and B is its base class.
For GCC compiler version 4.7 and later on, check ensures that B is direct base class of A.
Fixed dubious RTTI definitions.
CMake variable BUILD_ENABLE_FPE_SIGNAL_HANDLER was added to enable FPE signals during runtime.
Updated description of BUILD_ENABLE_FPE_SIGNAL_HANDLER_DESCR variable.
AIS_InteractiveContext::Remove (anIObj, ...) removes object from sequence of detected owners.
Therefore further iteration on detected will not require updating this list with ::MoveTo().
Additional modification includes incrementing properly the iterator of CurrentDetectedObject
and resets iterator of Highlighted detected objects, because nothing is really highlighted after that.
Handling of children objects located on sub-labels of the main child label is enabled in method CopyChildren(); TagSource attributes for such children are copied in method Clone()

Now, GeomPlate_BuildPlateSurface accepts base class Adaptor3d_HCurve and of course array of Adaptor3d_HCurve.
Classes GeomPlate_Array1OfHCurveOnSurface and GeomPlate_HArray1OfHCurveOnSurface have been renamed to GeomPlate_Array1OfHCurve and GeomPlate_HArray1OfHCurve correspondingly.
Documentation has been updated.
Correction in documentation.
1. The result of Boolean operation on the arguments of collection type, containers WIRE/SHELL/COMPSOLID, is also a collection.
The containers of type WIRE included into result should now also (as the SHELLs) have coherent orientation of its sub-shapes.
For that the new method has been implemented (BOPTools_AlgoTools::OrientEdgesOnWire(TopoDS_Shape&)) which reorients edges for correct ordering.
The duplicating containers, i.e. containers with the contents completely included in other containers, are now avoided in the result of BOP.
2. The result of Fuse operation on Compsolids is now also will be Compsolid.
3. Documentation has been updated.
4. New test cases for the issue.
5. Adjusting test cases to current behavior.
Correction of test case bugs/modalg_4/bug726_2 according to the new behavior
- SelectMgr_SelectableObject::ClearHighlighted method is added to remove dynamic highlight data;
- interactive context will pass processing of dynamic highlight erase to the object if the owner returns false in SelectMgr_EntityOwner::IsAutoHilight;
- if owner returns true in SelectMgr_EntityOwner::IsForcedHilight, selection presentation will be re-highlighted at each ::Select call;
- redundant logic related to old object-oriented highlight mechanism was removed from AIS_InteractiveContext::MoveTo.
The method for building splits of the face BRepOffset_MakeOffset::BuildSplitsOfFace has been redesigned to use the BOPAlgo_BuilderFace algorithm directly.
The methods FindInvalidFaces and TrimNewIntersectionEdges have been corrected to avoid possible instabilities.
The filtering of invalid edges by existing bounding edges has been corrected to avoid removal of valid splits.
The method BRepOffset_Analyse::Correct2dPoint has been modified to avoid unnecessary initialization of BRepAdaptor_Surface.
Adjustment of the test cases.
Test case bugs modalg_6 bug26513 has been modified to unify faces of the input shape before operation.
BOPAlgo_CheckerSI crashed due to building of pcurve for an edge not lying on surface. The fix avoids building of pcurves in this algorithm.
The new flag has been added in BOPAlgo_PaveFiller class (method SetAvoidBuildPCurve). It tells whether to avoid building pcurves. It is worth to set if the result is not used to create splits of faces, as in example with BOPAlgo_CheckerSI.
Static variable holding handle to the last raised exception is made thread-local on compilers that support C++11 keyword thread_local (MCVC++ 14+, GCC 4.8+, ICC 14+, CLang).
Test bugs fclasses bug28217 is added (BAD on vc < 14 and gcc < 4.8).
Test case tuning bugs/fclasses/bug28217
Eliminated usage of ANSI methods.
All Visual Studio projects generated by genproj or CMake use Unicode character set.

Updated documentation about building of occt for UWP and Android via CMake.
Eliminated CMake warning CMP0054 for Android platform build.
FFP state management (light sources, matrices, clipping planes) has been
moved to OpenGl_ShaderManager for consistency with Programmable Pipeline.
OpenGl_Context::BindProgram() does not re-bind already active Program.
OpenGl_PrimitiveArray::Render() does not reset active Program at the end.
OpenGl_Context::ApplyModelViewMatrix() now checks if matrix differs
from already set one before modifying state in Shader Manager.
This allows avoing redundant state changes, matrix uploads onto GPU
and re-computation of inversed matrices.
NCollection_Mat4 has been extended with equality check operators for proper comparison.
OpenGl_ShaderManager - the tracking Material state has been added.
Removed unreachable states OPENGL_NS_RESMAT, OPENGL_NS_TEXTURE and OPENGL_NS_WHITEBACK.

invalidated within OpenGl_VertexBuffer::unbindFixedColor().
OpenGl_Workspace::ApplyAspectFace() - fixed invalidating Material State
when only Highlighting style is changing.
The method BOPTools_AlgoTools2D::AttachExistingPCurve has been corrected so that
to call BRepLib::SameParameter not on the target edge with the whole set of pcurves,
but rather on a temporary edge with 3D curve and copied pcurve only.
After that the updated pcurve is transferred to the target edge.
Small correction of test case for issue CR28221
Cosmetics, code clean up.
AIS_ColorScale now draw labels using Graphic3d_VTA_CENTER
vertical alignment flag, instead of incorrect own alignment logic.
The color bar now adds margin on the top simmetrical to the bottom.
AIS_ColorScale::SetSmoothTransition() - added new property
for displaying colorscale with smooth transition between color intervals.
AIS_ColorScale::SetHueRange() - added new property defining the hue angles
corresponding to minimal and maximum values on the color scale.
AIS_ColorScale::SetLabels() now allows setting the sequence of free labels,
which number does not match the number of intervals.
In this case the labels will be displayed at positions of virtual
intervals corresponding to the number of labels.
Disable SetSingleSolutionFlag when calling algorithm of curve-curve Extrema.
Now DistShapeShape will find all solutions, even if they are located on the same pair of edges.
The fix brings the speed down for the cases of coinciding curves.
Several improvements have been made in BO code to fix the bug:
- Create empty edge-edge interference if intersection is close to an end vertex. This will help to avoid creation of unnecessary edge-face intersections.
- Improve PutPaveOnCurve() method to join nearly located vertices when they are put on the same section curve.
- Add processing of same-domain vertices for section edges in UpdatePaveBlocks() method.
- Improve the method CorrectWires() in order to not increase vertex tolerance if it will cover the major part of an edge.
- Replace vertices of section edges by same-domain equivalents.
- In the algorithm BOPAlgo_WireSplitter, correct angles computation and evaluation, taking into account periodicity.
- Modify PostTreatFF to properly take into account the orientations of coinciding section edges.
- In IntTools_Context::ComputePE, check distance from the point to vertices of the edge if the projection to the curve is failure.
Tests update:
- test offset\faces_type_i\C9 has been updated; now instead of returning bad shape it returns null result.
Notes for porting:
- Modify BopAlgo_PaveFiller so that on output each interference refers to the new vertex that will hit in the result (same-domain of the initial new vertex).
- Make the method BOPDS_DS::Index() returning valid index for new shapes.
// eliminate compile warning on VC14
Draw command 'proj' has been improved:
- Add possibility to pass the starting point. If it is passed than the algorithm Extrema_GenLocateExtPS is used instead of standard projection.
- Make the output of the command more clear.

StdSelect_BRepSelectionTool methods have been corrected to take
SelectMgr_EntityOwner instead of StdSelect_BRepOwner.

// correct test case
- class Graphic3d_HatchStyle is added to provide a possibility to set up custom and predefined hatching;
- added the ability to set custom hatch patterns through bitmaps;
- test case for issue #28107
1. Algorithm of orthogonalize of the transformation matrix (in gp_Trsf(2d) classes) has been documented.
2. Algorithm of computation of intersection line in case of two intersected cylinders (implemented in the fix for issue #24915) has been documented. Additionally, I would like to tell about some advantages of new algorithm in compare with old one.
2.1. Both algorithm generates intersection points for Walking-line (WL), which will be approximated to B-spline curve(s) in the future. At that, new algo (in compare with old one) uses another method for step computation. It based on attempts to provide equal steps (if it is possible) along V-direction (instead of U-direction used in old algorithm). It allows obtaining set of points, which are more uniform distributed in compare with old algo (this problem is the main reason why case #24915 was failed). Of course, we will get non-uniform distribution along U-direction. However, it can be compensated by small range (its length is less or equal 2*PI) of U-parameter change, whereas range of V-parameter can be very big.
2.2. More simple estimation of curvature "jump". New algo aims at provide equidistant distribution of points along V-direction. If it requires "jump" of U-parameter then we have "jump" of curvature in this point. This check is implemented in function AddPointIntoWL(...) (see place where SeekAdditionalPoints(...) is called).
However, in OCCT 7.1.0, curvature jumping is analyzed (it was not earlier, when the bug #24915 was fixed) - see fix for issue #27431.
2.3. New algorithm allows obtaining 7D-intersection point immediately. At that, old algorithm computed only 2D-intersection point (on some one surface). After that, it computed 3D-intersection point and, finally, projected(!) 3D-point to the second surface in order to obtain second 2D-intersection point. This second projection results in some problems. One problem is described in the issue #27968 (see message ~0058807). Second problem is the process of cases with singularity (significant improvement in this direction has been made in the fix#27431). Third problem is difficulties in projection itself (e.g. if we project point to a sphere when V-coordinate of the projection is near to PI/2 - projection point is found but not precise; the reason is not singularity but small radius of V-isoline).
Method used in new algorithm allows avoiding these problems. However, at present, it is implemented for case of two cylinders intersection (where most of these problems are not actual).
2.4. Algorithm of search of intersection point on surface boundary(ies) has been changed, too. Old algorithm sought point on boundary irrespective of intersection line. It resulted in problems described in the issue #27252 and related. New algorithm looks for intersection point of intersection line with surface boundary. It requires rectangular domain. However, it is not problem for current OCCT-version.
The method to find common Vertices and Edges between faces
BRepOffset_Tool::HasCommonShapes(const TopoDS_Face&,
const TopoDS_Face&,
TopTools_ListOfShape&,
TopTools_ListOfShape&)
has been re-implemented using maps and renamed to BRepOffset_Tool::FindCommonShapes.
The new method
BRepOffset_Tool::FindCommonShapes(const TopoDS_Shape&,
const TopoDS_Shape&,
const TopAbs_ShapeEnum,
TopTools_ListOfShape&)
has been implemented to look for the common shapes of given type.
1. The possibility to prevent addition of internal parts has been added into the following algorithms:
- BOPAlgo_BuilderFace;
- BOPAlgo_BuilderSolid;
- BOPAlgo_MakerVolume.
Setting the option to avoid internal parts for MakerVolume algorithm guarantees that the result solids
will be manifold and not contain any internal parts. But it does not prevent from occurrence
of the internal edges or vertices in the faces.
2. The Set/Get methods of the BOPAlgo_BuilderArea class have been made inline.
3. Draw command mkvolume has been updated to take into account the new option.
4. BRepOffset_MakeOffset::BuildShellsCompleteInter() has been modified to use the new option of BOPAlgo_MakerVolume
to speed up the construction of the final result solid.
5. Documentation has been updated with new section dedicated to BOPAlgo_MakerVolume algorithm.
6. Test case for the issue.
Added information about removed classes StdPrs_WFDeflectionShape,
Prs3d_WFShape, StdPrs_ToolShadedShape and removed property
AIS_InteractiveObject::SelectionMode().
1. Unification of the usage of the BRepAdaptor_Surface in Boolean Operations algorithm.
For each face when it is necessary the Adaptor is initialized only once and stored in Context.
For that purpose the new IntTools_Context::SurfaceAdaptor(const TopoDS_Face&) method has been implemented.
To provide possibility to take the Adaptor from the context, the context has been added as
a parameter in following methods:
BOPTools_AlgoTools::MakePCurve()
BOPTools_AlgoTools::Sence()
BOPTools_AlgoTools2D::BuildPCurveForEdgeOnFace()
BOPTools_AlgoTools2D::PointOnSurface
BOPTools_AlgoTools2D::CurveOnSurface
BOPTools_AlgoTools2D::AdjustPCurveOnFace
BOPTools_AlgoTools2D::Make2D
BOPTools_AlgoTools2D::MakePCurveOnFace
BOPTools_AlgoTools3D::GetNormalToFaceOnEdge
It is also possible now to pass the context into BOPAlgo_WireSplitter algorithm.
Also, the new IntTools_Context::UVBounds(const TopoDS_Face&) method
has been implemented to get the UV bounds of a face.
2. Additional improvement is a calculation of reduced intersection range only for the intersection
type VERTEX during computation of Edge/Face interference.
3. The methods IntTools_EdgeFace::Prepare() and IntTools_EdgeFace::FindProjectableRoot()
and the fields IntTools_EdgeFace::myProjectableRanges and IntTools_EdgeFace::myFClass2d
have been removed as obsolete.
4. Test cases for the issue.
The Gluing operation is an additional option for the algorithms in the Boolean Component
such as General Fuse, Boolean operations, Section operation, Maker Volume and Cells Builder algorithms.
The Gluing options have been designed to speed up the computation of the interference among arguments of the operations on special cases,
in which the arguments may be overlapping but do not have real intersections between their sub-shapes.
This option cannot be used on the shapes having real intersections, like intersection vertex between edges,
or intersection vertex between edge and a face or intersection line between faces.
The Gluing option is an enumeration implemented in BOPAlgo_GlueEnum.hxx. There are following items in the enum:
* BOPAlgo_GlueOff - default value for the algorithms, Gluing is switched off;
* BOPAlgo_GlueShift - Glue option for shapes with partial coincidence;
* BOPAlgo_GlueFull - Glue option for shapes with full coincidence.
For setting the Gluing options for the algorithm it is just necessary to call the SetGlue(BOPAlgo_GlueEnum) method with appropriate Glue value.
For using this option in DRAW the command bglue has been implemented:
* 0 - default value, Gluing is off;
* 1 - for partial coincidence;
* 2 - for full coincidence
Elimination of the warnings.
In the case of infinite point due to not enough machine precision the distance from the point to each edge of the face is computed the same, and the algorithm cannot correctly select the nearest edge. To solve this problem checking of point was added, if the point is located too far from the bounding box of the face, then it will be replaced with another point located on the line between the point and the center of the bounding box.
The new point has the same state as initial one but its state can be resolved without ambiguity.
Corrections in CheckPoint method

Character set option of VS project Unicode is used instead of preprocessor definitions for UWP projects.
OpenGl_LayerList::Render() now calls glDepthMask(GL_TRUE) before clearing depth buffer.
Depth buffer is now cleared even if ZLayer with this command has no structures.
1. Special usage of the common edges not belonging to any invalidity while rebuilding the invalid faces (method IntersectFaces() in BRepOffset_MakeOffset_1.cxx).
Such edges could only be extended to the valid faces boundaries, thus could only split the face and not create any new part.
2. Test cases for the issue.
Treatment of paths in Resource_Manager is corrected to handle properly paths with dots inside.
Extraction of extension from path in DOS mode when working on Linux is corrected in OSD_Path.

Mehtod HasIntersection added in NCollection_Map to check whether two given maps contain at least one same item.
'Draw' command and test to check the method were created.
Select3D_SensitiveSet now stores BVH_PrimitiveSet as class field (no dynamic allocation),
and BVH_PrimitiveSet subclass now stores raw pointer to Select3D_SensitiveSet (no smart pointer).
Select3D_BVHPrimitiveContent definition has been moved into Select3D_SensitiveSet
class definition to avoid confusion.
Unused field Select3D_SensitiveSet::myIsLeftChildQueuedFirst has been removed.
The algorithm BRepExtrema_DistShapeShape has been protected against exceptions when non-geometric shape data is given on input, like a face containing triangulation only or an edge containing polygon only. Such faces/edges are ignored by the algorithm.
BRepGProps::VolumeProperties() now ignores faces without geometric surface to avoid access violation.
OpenGl_Workspace::BufferDump() now implicitly converts RGBA dump
into requested BGR, BGRA and RGB image.
DRAW command dversion is improved to report OpenGL variant used (desktop or ES); reporting of version of MSVC is corrected for VC14 and above; reporting of HAVE_OPENCL option is removed.
Usage of command vdump is corrected in some tests to specify extension .png for an image file.
Compiler warning is eliminated in OpenGl_Text.cxx (OpenGL ES mode only).

Check that face lies on the periodic surface was added.
Added check between ends of 2D curves in the 3D space and vertex the same which used in the BRepCheck_Wire::SelfIntersect
Test case for issue CR28094 has been created.
The whole piece of the walking line between two vertices is no more checked for having length greater than Precision::Confusion(). Instead, only full duplicate points (comparing with gp::Resolution()) are removed, allowing the resulting line have any non-null length.
The test bugs modalg_6 bug27720_5 has been reverted to its original state.
Exception is raised during translation BSpline curve having only one unique knot.
Protection for such case was added
Added protection against exception during reading BSpline curve with number of control points equal to 0

Test case for issue #27575
OCAF attributes TDataStd_AsciiString, TDataStd_Integer, TDataStd_Name, TDataStd_Real are extended by possibility to use custom GUID.
Now multiple attributes of any of these types can be placed at the same label using different user-defined GUIDs.
For this new "Set" methods were added into each attribute, which takes this custom GUID as an argument.
Other aspects of management of attributes on labels remain the same.
Version number of persistent OCAF documents is incremented.
However, the attributes are stored in the same way unless non-standard GUID is used for particular attribute.
Previously saved documents are fully supported, but the new documents with this extension used will be non-readable by the previous version of OCAF libraries.
Problem of projection of line on the cone in the special case when starting point of the line coincides with the cone apex is fixed (by shifting this point along the source line).
Warning message was updated to show actual information.
Additional checking of type of shape was added to prevent exceptions for Add Dimension functionality.
Broken custom presentations Sample2D_Text and ISession_Text
have been replaced by AIS_TextLabel.
ISession2D_Curve::Compute() - fixed defining the group without presentation aspects.
GeomSources - fixed assigning custom attributes.
1. BRepOffset_Inter3d::ConnexIntByInt
Create unique offset edge for each localized part shared between pair of faces of the input shape.
2. Test cases for the issue.
Extension on the 3D Offset algorithm (Mode="Complete", Join Type = "Intersection")
for colliding cases to add support for new configurations of the shapes.
In the previous approach the result of the offset operation was build from
the offset faces using MakerVolume algorithm, without checking of the validity of these faces.
The new extension is based on this approach, but now the offset faces are being checked
on invalidity and rebuild in case of any. This allows (in case of successful rebuilding) to avoid creation
of the unforeseen parts such as dangling parts, spikes, inverted faces in the result of offset operation.
The main criteria for the validity of the faces is the coincidence of the normal
direction of the offset face with the normal direction of the original face.
Check for removal of invalid faces has been removed as obsolete.
BRepOffset_Inter2D: Avoid excess trimming of the edges due to coincidence with other edges.
BRepOffset_Inter3D: Careful treatment of the intersection of the faces connected only through vertices.
Eliminating the compiler warning.
Small corrections of test cases for issue CR26917
When fuzzy option is in force prevent increasing tolerance of input shapes. Instead pass increased by fuzzy value the tolerances of sub-shapes everywhere where it is needed by intersection algorithms.
The following changes in API have been made:
- The methods SetFuzzyValue and FuzzyValue have been moved from the classes BOPAlgo_ArgumentAnalyzer, BOPAlgo_Builder, and BOPAlgo_PaveFiller to the base class BOPAlgo_Algo.
- The public method BOPDS_DS::VerticesOnIn has been renamed to SubShapesOnIn, and the new output parameter theCommonPB has been added.
- In BOPTools_AlgoTools, a new argument "theFuzzyValue" has been added in the methods ComputeVV and AreFacesSameDomain.
- In IntTools_Context, a new argument "theFuzzyValue" has been added in the methods ComputeVE and ComputeVF.
- The methods SetFuzzyValue and FuzzyValue have been added in the classes IntTools_EdgeEdge, IntTools_FaceFace.

- The new argument "theTol" has been added in the method IntTools_WLineTool::DecompositionOfWLine.
Some improvements in algorithms have been made during fighting with regressions:
- Correct initialization of pave blocks for degenerated edges.
- In BOPAlgo_PaveFiller::MakeBlocks(), filter out paves on intersection curve that were put on the curve accidentally due to wide range of E-F intersection vertex.
- In the method IntTools_Tools::ComputeTolerance the margin added to the computed tolerance has been increased up to 0.001%.
- The method BOPAlgo_PaveFiller::PutPaveOnCurve has been corrected in order to use the original vertex tolerance instead of the value increased during putting it on other curves.
- The new method BOPDS_PaveBlock::RemoveExtPave has been added.
- The vertex tolerance computation in BOPTools_AlgoTools::CorrectCurveOnSurface has been improved, taking into account intersection segments between p-curves (to avoid regression on "bugs modalg_6 bug22794").
- Improve IsExistingPaveBlock to make more stable catching of coincidence of common block with section curve (against regression "bugs modalg_4 bug697_2" on Linux).
Test case for the bug has been added.
The following test cases have been updated as improvements:
boolean gdml_private ZH2 ZI7 ZJ7
boolean volumemaker C4
The test case bugs/modalg_4/pro19653 has been corrected to make it stable. See comment inside the script for details.
The test case bugs/modalg_6/bug25880 has been corrected to suppress wrong bfuse commands.
The test bugs/modalg_6/bug26954_3 has been corrected to compare the result with more precise reference value.
The "faulty" TODO in boolean/volumemaker/A8 has been made actual for Linux as well.
//Eliminate compilation error on Linux.
Class Dico_Dictionary was replaced by NCollection_DataMap/NCollection_IndexedDataMap classes.
Changed argument name in template class NCollection_Datamap to eliminate redefinitions of static members in dependent code.
The shape after scaling contains PCurves with incorrect parametrization, because of too large tolerance given.
1. Set Precision::PConfution() as a tolerance for GeomLib::SameRange.
2. Do not take into account tolerances of vertices while calculating tolerance of transformed PCurve for edge.
3. Test case bugs/modalg_6/bug28028
Checking of number of knots is added. If number of knots more then allowed value, algorithm does not search distance between curves for each knot interval, but uses predefined sample point distribution.
This change was born in the scope of work on the issue 26329, but does not have direct connection to it. Therefore it has been postponed to be integrated later in its own context.
Test case for issue #28030
Purger has been disabled (in IntPatch_PrmPrmIntersection algorithm) if some points have been added in the Walking line (it is stupidly, first, to insert some points in the line and, after that, to delete points from this line).
Some improvements in IntWalk_PWalking::SeekPointOnBoundary(...) method have been made (see comments in the code for detail information).
Some test cases have been adjusted according to their new behavior.
The method BRepOffsetAPI_MakePipeShell::Generated now returns generated shapes for sub-edges and sub-vertices of sections.

Toolkit 'TKHLR' was fully refactored for 'Standard_Address' and macros except about half of package 'HLRBREP' there 'Standard_Address' is used through the 'generic' mechanism.
Check for null shape has been added in the command addsweep implementation.
// eliminate warning
Test case for issue CR24932
Test case has been corrected.
- added implementation of mentioned methods for neutral point;
- sequence of detected objects was replaced by sequence of detected owner's indexes in AIS_InteractiveContext;
- commands vselnext and vselprev were corrected to update viewer properly;
- test case for issue #27530.
The algorithm in WorkWithBoundaries::BoundaryEstimation(...) did not take into account opposite directions of cylindrical axes (when the angle between them is obtuse). After the fix it does it.
Small correction of test cases for issue CR28009
The root of the problem is incorrect processing of cases when intersection line goes through the apex(es) of sphere. The fix improves this situation. The algorithm is taken from DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx file). Before the fix, faltering steps were done to solve this problem. As result, it worked in some particular cases. Now, its possibilities have been extended significantly.
Following changes have been made in the fix:
1. Class IntPatch_ALineToWLine has been rewritten cardinally. It touches as interfaces of existing methods as adding/removing some methods/fields. Correction touches both cases: going through seam of Cone/Sphere and through pole(s) of sphere. Old interface did not allow making some actions with analytical line (ALine), e.g. splitting it on several Walking-lines (WLine).
2. Restriction-line support has been removed from Implicit-Implicit intersection result (see IntPatch_Intersection::GeomGeomPerfom(...) method). It connects with the fact that the intersection algorithm itself returns precise intersection line in analytical cases (in compare with parametric intersector). Therefore, we do not need in additional (restriction) line.
3. New class IntPatch_SpecialPoints has been added. This class contains methods to add some special points (such as apex of cone, pole of sphere, point on surface boundary etc.) in intersection line (IntPatch_PointLine). It is based on the static functions, which already exist in IntPatch_ImpPrmIntersection.cxx file (these functions have been moved to the new class).
4. Method IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) has been renamed to IntPatch_WLineTool::ExtendTwoWLines(...). It is connected with changing main idea of the method. Now it allows extending WLine to the surface boundary or to the singular point (if it is possible): cone apex, sphere pole etc. Interface of this method has been corrected, too. At that, old functionality (extending to each other) has been kept. For implementation of this algorithm, new enumeration "IntPatchWT_WLsConnectionType" has been created.
5. Method IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) has been added. See IntPatch_PointLine.hxx for detail information. It allows correct step computing depended on the local curvature of the intersection line. This method uses geometrical properties of intersected surfaces to compute local curvature. Therefore, it can be applied in wide range of cases even if the intersection curve is not represented in explicit form (e.g. in case of param-param-intersection).
6. Method IntSurf::SetPeriod(...) has been created.
7. Additional check has been added in Draft_Modification::Perform() method for better choice of correct fragment of intersection line for processing DRAFT operation.
8. New overload method IntPatch_Point::SetValue() has been added.
9. Some refactoring of the code has been made.
Creation of test case for issue #27431.
---------------------------------------------------------------------------------------------
Some test cases have been adjusted according to their new behavior.
tests\bugs\modalg_4\bug62
It is really IMPROVEMENT (but fortuitous).
tests\bugs\modalg_5\bug25838
The behavior of this test has been reverted to the state before fixing the issue #27341. Main problem has not been fixed in #27341. It was fortuitous improvement.
tests\bugs\moddata_2\bug565
Quality of intersection curve was not checked. And the curve is bad on both MASTER and FIX. Input data are really wrong: plane-like-cone. However, on the MASTER, four intersection curves (the quality is insignificant) are expected. On the fix, not empty intersection result is expected simply.
tests\boolean\volumemaker\A8
Differences in images and CPU is expected. Difference in images is expected to be fixed in the issue #26020. Now, we should apply this behavior.
Much CPU time is spent by IntTools_FaceFace::ComputeTolReached3d(...) and GeomInt_IntSS::BuildPCurves(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.

CPU difference is expected. Much CPU time is spent by IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) method calling. This method is really new (it does not exist on the MASTER) and is really useful. Therefore, we should apply new behavior.

CPU difference is expected. Much CPU time is spent by IntTools_WLineTool::DecompositionOfWLine(...) and IntTools_FaceFace::ComputeTolReached3d(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.

Differences in images is expected. The test keeps its BAD status on the FIX. But the result on the fix is nearer to expected than on the MASTER. Issue #27014 is still actual. As before, it is not clear, why the number of entities is different. The number of section curves has not been changed. Interfered entities are the same as on the MASTER.

The reason is described in the issue #27896.
Small correction in the test case
Implement new function to find Product_Definition_Shape entity.
Modify Reader to add possibility of import DGTs, connected to some geometry items.

File resources are still used instead of embedded programs
when CSF_ShadersDirectory is defined, but this functionality
is intended for OCCT development.
Enumeration Graphic3d_ShaderProgram::ShaderName_Phong
demonstrating custom GLSL program usage has been removed.
The SolidClassifier algorithm does not take into account the internal parts of the solid and its faces.
But in some cases the parts which are internal on some shapes can be included in other shapes of
the same solid with FORWARD/REVERSED orientation and therefore should be counted as well.
The fix changes the procedure of the initialization of the tree of bounding boxes of the edges and
vertices of the solid in SolidExplorer algorithm to treat the internal/external parts of the solid correctly.
Avoid getting non-existing array items. Use reference to array items instead of pointers where it is possible.
Create test case. Before the fix this test raised exception in debug mode.

Overview project regenerates documentation if any source file was changed.
While checking the section edges between pair of faces on coincidence with the
existing edges use for checking only the edges from these two faces.

So, in successor class BinDrivers_DocumentRetrievalDriver this allows clearing the BinMNaming_NamedShapeDriver set of stored shapes when it is not needed anymore.
OpenGl_Structure::Render() and SelectMgr_ViewerSelector::checkOverlap()
now clip entire zoom/rotate persistence object
by checking anchor point with global clipping planes.
Image dump has been added to the new test case.
OpenGl_ShaderManager, per-vertex shading and per-fragment shading
- do not apply model-world matrix on the light sources
which are expected to be defined in world-space.
Now, the algorithm tries to estimate U- and V-ranges of future intersection curve(s) on the surface. This information is used in stop-criterium of the algorithm instead of full surface range used earlier. It allows reducing dependencies of intersection result on the surface ranges.
Tuning of test case bugs/modalg_6/bug27937_1
The branch contains a fix on Undo/Redo for TPrsStd_AISPresentation attribute + an opportunity to deselect the interactive object.
getData() now calls FindAttribute(), the field myData disappeared.
A fix of regression on bug73_3.
A cleverer solution.
1. VRange of intersection curve has been limited. As result, too oblong intersection curve(s) will be never returned.
2. Now, purger algorithm is not called for lines obtained by Geom-Geom intersection method.
3. New statuses are entered in IntPatch_ImpImpIntersection class. It makes intersection algorithm more informative and flexible for using.
4. Method IntPatch_ImpImpIntersection::GetStatus() has been created.
Tuning of test case bugs modalg_6/bug26894
1. Unification of trimmed and not-trimmed cylinders processing (IntPatch_Intersection::GeomGeomPerfomTrimSurf() method has been removed).
2. Interface of IntPatch_ImpImpIntersection::Perform(...) method has been changed.
3. Now, WLine purging is forbidden for Geom-Geom-Intersection.

Adjusting test cases according to their new behavior.
For debugging and performance analysis it is reasonable to provide the ability to rebuild ray tracing shaders on the fly.
In this way, it will be possible to analyze the impact of different shaders modifications
without re-launching and re-configuring the scene.
This functionality can be used in the following way:
> vrenderparams -rebuild
AIS_ColoredShape::Compute() - add NULL shape check.
AIS presentations - removed redundant clearance within ::Compute()
which is always done in advance within PrsMgr_PresentationManager::Update().
Incorrect result of classification of a point relatively a solid leads to faulty interferences between vertices/edges of one solid with another one. Classification has been corrected by checking if an auxiliary point in face coincides with the face boundary in 3D space.
Test case has been created.
Added DRAW command dsetsignal, resetting OSD signal handler with either armed or disabled FPE handler, according to an option.
If called without arguments, it sets FPE handler only if environment variable OSD_FPE is defined (with value different from 0).
On start, DRAW calls dsetsignal to set FPE signal if CSF_FPE is defined.
Test bugs fclasses bug6143 uses dsetsignal to set FPE handler unconditionally before the test command, and resets it to default at the end.
A number of changes in the code have been done in order to fix floating point exceptions that became generated after enabling signals:
- Global functions Sinh() and Cosh() defined in Standard_Real.hxx are improved to raise Standard_NumericError exception if argument is too big (greater than 710.47586), instead of relying on system treatment of floating point overflow. These functions are used instead of sinh and cosh in ElCLib.cxx.
- Maximal value of parameter on hyperbola is restricted by 23 (corresponding to ~1e10 in 3d) in order to avoid FP overflow in Extrema_GenExtCS.cxx, ShapeFix_EdgeProjAux.cxx.
- Interface of the root curve adaptor class Adaptor3d_Curve has been updated to add new virtual methods BasisCurve and OffsetValue. They complement the adaptor for the case of offset curves. These methods are used in Extrema_GenExtCS.cxx to restrict domain search in the case of offset of hyperbola, in order to get rid of floating point overflow. All classes inheriting Adaptor3d_Curve have been changed to implement the new virtual methods.
- Protection against division by zero has been implemented in ApproxInt_KnotTools.cxx, BRepClass3d_SClassifier.cxx, BRepGProp_Face.cxx, BRepMesh_FastDiscretFace.cxx, Geom2dGcc_Circ2d2TanOnIter.cxx, Geom2dInt_Geom2dCurveTool.cxx, IntPolyh_MaillageAffinage.cxx.
- Protection against calling of math functions of infinite arguments has been added in BRepCheck_Edge.cxx, BRepLib.cxx, CSLib_NormalPolyDef.cxx, Extrema_FuncExtPC.gxx, Extrema_GExtPC.gxx, Extrema_GLocateExtPC.gxx, Intf_InterferencePolygonPolyhedron.gxx, ShapeAnalysis_Surface.cxx, ShapeAnalysis_TransferParametersProj.cxx, ShapeAnalysis_Wire.cxx, math_FunctionSetRoot.cxx.
- Proper initialization of local variables is done in BOPAlgo_PaveFiller_6.cxx, XSDRAWSTLVRML.cxx.
- Inconsistent usage of Standard_Boolean* to access integer data in HLR (caused by #27772) is corrected
Some test cases have been updated to actual state.
Resource_Manager now sets RWXD permissions for the created directories to allow their removal.
Method OSD_Directory::Build() will create intermediate directories if they do not exist yet.
OSD_FileNode is corrected to clean error status in method Exists().
Tests bugs fclasses bug181_1 and bug181_2 are corrected to check existence of generated resource files; TODO is removed in bug181_2.

- remaining occurrencies of hard-coded 0 selection mode were corrected to use global selection mode;
- test case for issue #27983
- introduces a wrapper for setting up highlight properties: Graphic3d_HighlightStyle;
- API of all methods that use highlight or selection color is changed to deal with Graphic3d_HighlightStyle;
- highlight in shading mode now supports transparency, implemented via blending;
- transparency for selection can also be set, but implementing custom entity owners with additional presentation on application level;
- methods PrsMgr_PresentationManager::Highlight, PrsMgr_PresentationManager::BoundBox that highlight object with hard-coded color are removed;
- deprecated methods of SelectMgr_EntityOwner, that use presentation manager's highlight method, were removed;
- methods of IsHilighted AIS context with selection color checks were replaced;
- added API to store dynamic and selection highlight to Prs3d_Drawer class;
- customization of dynamic and selection highlight for particular objects is now available through SelectMgr_SelectableObject::HilightAttributes();
- AIS_InteractiveContext highlight methods were updated to support individual highlight styles of interactive objects;
- introduced new command - vselprops, that allows to customize global selection and highlight properties like autoactivation, pixel tolerance and colors;
- Draw Harness commands vautoactivatesel and vselprecision were removed, use vselprops instead;
- fixed bug in command's parser;
- test case for issue #27818
This commit provides useful functionality for path tracing rendering core.
1) Graphic3d_RenderingParams class was extended with additional AdaptiveScreenSampling option (disabled by default).
If this option is enabled, path tracing tries to adjust the number of samples for different screen areas.
In this way, the more complex areas (from the point of light conditions) are sampled more intensively,
while the simple areas are sampled very rarely.
For example, caustics and glossy reflections are typical candidates for more precise sampling.
In general, this allows to equalize image convergence and not to waste resources for already converged areas.
It is also possible to visualize sampling densities by enabling ShowSamplingTiles option
(activating and deactivating this option does not affect on the accumulated image).
2) Mixing OpenGL and ray-tracing output has been changed.
Now blending is performed using OpenGL functionality, while ray-tracing shaders only output correct Z-value.
Test case bugs vis bug27083 has been updated,
since the alpha value is now correctly set by Ray-Tracing to 1, opaque.
PrsMgr_PresentableObject, Graphic3d_Structure now consistently
take and store Handle(Geom_Transformation) instead of
TColStd_Array2OfReal / Graphic3d_Mat4.
Low-level advanced methods have been modified to pass Handle(Geom_Transformation).
High-level methods have been preserved accepting old syntax taking gp_Trsf.
Geom_Transformation now inlines most methods.
Graphic3d_Camera::TransformMatrices redundant NCollection_Handle usage
has been replaced with validity flags.
Graphic3d_TransModeFlags now defined as enumeration, not integer bit flags.
Graphic3d_TMF_PanPers and Graphic3d_TMF_FullPers have been removed.
Graphic3d_TMF_ZoomRotatePers has been introduced.
Graphic3d_TransformPers is now inherits Standard_Transient.
Graphic3d_TransformPers now defines dedicated constructors
for 3D persistence (zoom / rotate) and 2D persistence (2d / trihedron).
2D persistence now supports dedicated values for X and Y offsets.
The corner is now specified by enumeration Aspect_TypeOfTriedronPosition
instead of indirect interpretation of anchor point values.
Fixed handling of Graphic3d_TMF_ZoomRotatePers (combination of Graphic3d_TMF_RotatePers + Graphic3d_TMF_ZoomPers).
PrsMgr_PresentableObject, Graphic3d_CStructure now hold
Handle(Graphic3d_TransformPers) instead of a value.
Method ::SetTransformPersistence(), ::TransformPersistence()
now works with Handle(Graphic3d_TransformPers).
Old methods have been marked deprecated.
The reason of exception has been eliminated.
Creation of the test case for this issue.
Correction of unstable test case.
Some test cases have been adjusted according to their new behavior.
The algorithm that builds outlines ("silhouettes") makes an outline in 2d parametric space of the surface starting from some previously detected point where normal is orthogonal to direction of view. So, the surface is previously discretized into (m*n) sample points and some of them become starting points for future outlines.
If the surface has non-uniform parametrization and/or some local extremums of curvature, the outlines can not be built without breaks, so there are several groups of consequent outlines in this case. Unfortunately, it leads to the situation when current number of sample points becomes insufficient to build all the parts of outlines.
The idea is to detect the "holes" between already constructed parts of outlines and then complete the construction.
New auxiliary draw command for testing of HLR.
Correction according to the remarks.
Update of test case according to the developer's directive
The GeomFill_NSections algorithm cannot create any surface from sequence with single curve only.
Therefore, return is provided in corresponding place of the code. Additionally, some public methods of GeomFill_NSections class checks if the surface has been created earlier.
Test case for this issue has been created.
Compiler error has been eliminated.
0027734: Configuration - TKIVtkDraw build fails with TBB: Remove unnecessary define statement (windows specific).
Small correction of test case for issue CR27567
TCollection_ExtendedString/TCollection_AsciiString description
has been updated to reflect usage of this classes for Unicode strings.
TCollection_ExtendedString now defines constructor taking wchar_t* (all platforms)
and method ::ToWideString() returning wchar_t* (Windows only).
TCollection_AsciiString now defines constructor taking wchar_t*.
TCollection_ExtendedString/TCollection_AsciiString now defines
auxiliary methods ::StartsWith() and ::EndsWith().
TCollection_ExtendedString internals has been updated to eliminate
duplicated code for converting between UTF-16 and UTF-8.
Code has been cleaned up from redundant explicit conversions to wchar_t*.
Global method OSD_OpenStream()/OSD_OpenFileBuf() have been replaced
by C++ template to eliminate copy-paste for different STL collections.
OSD_SharedLibrary now uses wide-char system API call LoadLibraryExW()
on Windows for consistency.
New macro Standard_UNUSED has been added for marking possibly unused functions and variables
(to suppress gcc/clang compiler warnings).
Make protection of HLR algo against garbage data in faces. In particular case, there are faces built on a periodical surfaces, which U bounds exceed period thousands times. Such faces are excluded from the process of edges hiding.
In addition, while fitting the intersection point in period for periodical faces, replace looping with the single call to AdjustPeriodic method.
- Add new test case.
- Update tests of HLR according to new numbers of subshapes.
Update of test cases according to the new behavior
Graphic3d_SequenceOfHClipPlane now inherits Standard_Transient.
PrsMgr_PresentableObject, Graphic3d_Structure, Graphic3d_CStructure,
V3d_View, OpenGl_View now manages the plane list by Handle.
The getters ::GetClipPlanes() has been removed,
setters taking non-handle ::SetClipPlanes() has been marked deprecated.
OpenGl_Structure::Render() and SelectMgr_ViewerSelector::checkOverlap()
now disable global (view) clipping planes for objects
with flags Graphic3d_TMF_TriedronPers and Graphic3d_TMF_2d
or with new flag Graphic3d_SequenceOfHClipPlane::ToOverrideGlobal().
OpenGl_Clipping now implements interface for managing clipping planes
without copying the sequences.
The filtering of duplicates is no more performed by OpenGl_Clipping
- application is responsible to not do this.
OpenGl_Clipping tries avoiding unnecessary allocations for managing
list of active planes.
MFC sample has been updated to use V3d_View::ClipPlanes() method.
Graphic3d_TextureRoot - added methods Revision() and UpdateRevision()
for marking updates in texture data source.
OpenGl_AspectFace handles Graphic3d_TextureRoot::Revision() changes.
OpenGl_Texture::Init() now patches already allocated texture image when possible.
Graphic3d_Texture2D - added methods HasMipMaps()/SetMipMaps()
for configuring MipMap usage (as alternative to sub-classing).
Low-level selection algorithms has been improved to explicitly support 2D
transformation persistent objects. This patch generally touches:
1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three
subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH
tree. The algorithms are now have more flexibility to update only those trees
that is really required for actual camera state.
2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations
on BVH tree for 2d-persistent subset. Change of camera position does not
anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects.
3) Other classes from SelectMgr have been fine-tuned to provide appropriate API.
Porting notes:
This patch touches very low-level selection classes. If the low-level features were used
the following modifications may need to be considered for porting:
1) Iteration over objects of SelectMgr_SelectableObjectSet should now
be implemented with corresponding Iterator class.
2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return
Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type.

- *AIS_InteractiveContext::Hilight()*;
- *AIS_InteractiveContext::HilightWithColor()*;
- *PrsMgr_PresentationManager::Color()*;
- *SelectMgr_EntityOwner::HilightWithColor()*;
have been changed to receive *Graphic3d_HighlightStyle* instead of *Quantity_Color*.
Method *AIS_InteractiveContext::Hilight* is now deprecated and highlights the interactive object with selection style.
A group of methods *AIS_InteractiveContext::IsHilighted* has changed its behavior - now they only check highlight flags of the object or the owner in the global status. If the highlight color is required on the application level, it is necessary to use overloaded methods *AIS_InteractiveContext::HighlightStyle* for the owner and the object.
The following methods have been replaced in *AIS_InteractiveContext* class:
- *HilightColor* and *SetHilightColor* by *HighlightStyle* and *SetHighlightStyle*;
- *SelectionColor* setter and getter by *SelectionStyle* and *SetSelectionStyle*.
The API of *Prs3d_Drawer* has been extended to allow setting up styles for both dynamic selection and highlighting.

The following classes have been changed:
* *BVH_Sorter* class has become abstract. The list of arguments of both *Perform* methods has been changed and the methods became pure virtual.
* *Extrema_FuncExtPS* has been renamed to *Extrema_FuncPSNorm*.
* The default constructor and the constructor taking a point and a surface have been removed from class *Extrema_GenLocateExtPS*. Now the only constructor takes the surface and optional tolerances in U and V directions. The new method *Perform* takes the point with the start solution and processes it. The class has become not assignable and not copy-constructable.
* Constructors with arguments *(const gp_Ax22d& D, const gp_Pnt2d& F)* have been removed from *GCE2d_MakeParabola*, *gce_MakeParab2d* and *gp_Parab2d*. The objects created with some constructors of class *gp_Parab2d* may differ from the previous version (see the comments in *gp_Parab2d.hxx*). The result returned by *gp_Parab2d::Directrix()* method has an opposite direction in comparison with the previous OCCT versions.
* *BRepTools_Modifier* class now has two modes of work. They are defined by the boolean parameter *MutableInput*, which is turned off by default. This means that the algorithm always makes a copy of a sub-shape (e.g. vertex) if its tolerance is to be increased in the output shape. The old mode corresponds to *MutableInput* turned on. This change may impact an application if it implements a class derived from *BRepTools_Modifier*.
* The second parameter *theIsOuterWire* of method *ShapeAnalysis_Wire::CheckSmallArea* has been removed.
* In class *GeomPlate_CurveConstraint*, two constructors taking boundary curves of different types have been replaced with one constructor taking the curve of an abstract type.
* The last optional argument *RemoveInvalidFaces* has been removed from the constructor of class *BRepOffset_MakeOffset* and method *Initialize*.
* The public method *BOPDS_DS::VerticesOnIn* has been renamed into *SubShapesOnIn* and the new output parameter *theCommonPB* has been added.
@section upgrade_occt720 Upgrade to OCCT 7.2.0
@subsection upgrade_720_removed Removed features
The following obsolete features have been removed:
Management of highlight attributes has been revised and might require modifications from application side:
* New class *Graphic3d_PresentationAttributes* defining basic presentation attributes has been introduced.
It's definition includes properties previously defined by class Graphic3d_HighlightStyle (*Color*, *Transparency*),
and new properties (*Display mode*, *ZLayer*, optional *FillArea aspect*).
* Class *Prs3d_Drawer* now inherits class *Graphic3d_PresentationAttributes*.
So that overall presentation attributes are now split into two parts - Basic attributes and Detailed attributes.
* Class *Graphic3d_HighlightStyle* has been dropped.
It is now defined as a typedef to *Prs3d_Drawer*.
Therefore, highlight style now also includes not only Basic presentation attributes, but also Detailed attributes
which can be used by custom presentation builders.
* Highlighting style defined by class *Graphic3d_PresentationAttributes* now provides more options:
- *Graphic3d_PresentationAttributes::BasicFillAreaAspect()* property providing complete Material definition.
This option, when defined, can be used instead of the pair Object Material + Highlight Color.
- *Graphic3d_PresentationAttributes::ZLayer()* property specifying the Layer where highlighted presentation should be shown.
This property can be set to Graphic3d_ZLayerId_UNKNOWN, which means that ZLayer of main presentation should be used instead.
- *Graphic3d_PresentationAttributes::DisplayMode()* property specifying Display Mode for highlight presentation.
* Since Highlight and Selection styles within *AIS_InteractiveContext* are now defined by *Prs3d_Drawer* inheriting from *Graphic3d_PresentationAttributes*,
it is now possible to customize default highlight attributes like *Display Mode* and *ZLayer*, which previously could be defined only on Object level.
* Properties *Prs3d_Drawer::HighlightStyle()* and *Prs3d_Drawer::SelectionStyle()* have been removed.
Instead, *AIS_InteractiveObject* now defines *DynamicHilightAttributes()* for dynamic highlighting in addition to *HilightAttributes()* used for highlighting in selected state.
* The following protected fields have been removed from class *AIS_InteractiveObject*:
- *myOwnColor*, replaced by *myDrawer->Color()*
- *myTransparency*, replaced by *myDrawer->Transparency()*
- *myZLayer*, replaced by *myDrawer->ZLayer()*
* The method *PrsMgr_PresentationManager::Unhighlight()* taking Display Mode as an argument has been marked deprecated.
Implementation now performs unhighlighting of all highlighted presentation mode.
@subsection upgrade_720_implicit_viewer_update Elimination of implicit 3D Viewer updates
Most AIS_InteractiveContext methods are defined with a flag to update viewer immediatly or not.
Within previous version of OCCT, this argument had default value TRUE.
While immediate viewer updates are useful for beginners (the result is displayed as soon as possible),
this approach is inefficent for batch viewer updates, and having default value as TRUE
leaded to non-intended accidential updates which are difficult to find.
To avoid such issues, the interface has been modified and default value has been removed.
Therefore, old application code should be updated to set the flag theToUpdateViewer explicitly
to desired value (TRUE to preserve old previous behavior), if it was not already set.
The follow AIS_InteractiveContext methods have been changed:
@subsection upgrade_720_Result_Of_BOP_On_Containers Result of Boolean operations on containers
* The result of Boolean operations on arguments of collection types (WIRE/SHELL/COMPSOLID) is now filtered from duplicating containers.
@subsection upgrade_720_changes_methods Other changes
* Class GeomPlate_BuildPlateSurface accepts base class Adaptor3d_HCurve (instead of inherited Adaptor3d_HCurveOnSurface accepted earlier).
* Types GeomPlate_Array1OfHCurveOnSurface and GeomPlate_HArray1OfHCurveOnSurface have been replaced with GeomPlate_Array1OfHCurve and GeomPlate_HArray1OfHCurve correspondingly (accept base class Adaptor3d_HCurve instead of Adaptor3d_HCurveOnSurface).
* Enumeration *Image_PixMap::ImgFormat*, previously declared as nested enumeration within class *Image_PixMap*, has been moved to global namespace as *Image_Format* following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve previous name scheme for easy renaming of old values - e.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
@subsection upgrade_720_BOP_DataStructure BOP - Pairs of interfering indices
* The classes *BOPDS_PassKey* and *BOPDS_PassKeyBoolean* are too excessive and not used any more in Boolean Operations. To replace them the new *BOPDS_Pair* class has been implemented. Thus:
- The method *BOPDS_DS::Interferences()* now returns the *BOPDS_MapOfPair*;
- The method *BOPDS_Iterator::Value()* takes now only two parameters - the indices of interfering sub-shapes.
@subsection upgrade_720_Removal_Of_Old_Boolean_Operations_Draw Removal of the Draw commands based on old Boolean operations
* The commands *fubl* and *cubl* have been removed. The alternative for these commands are the commands *bfuseblend* and *bcutblend* respectively.
* The command *ksection* has been removed. The alternative for this command is the command *bsection*.
@subsection upgrade_720_Change_Of_FaceFace_Intersection Change of Face/Face intersection in Boolean operations
* Previously, the intersection tolerance for all section curves between pair of faces has been calculated as the maximal tolerance among all curves.
Now, each curve has its own valid tolerance calculated as the maximal deviation of the 3D curve from its 2D curves or surfaces in case there are no 2D curves.
* The methods *IntTools_FaceFace::TolReached3d()*, *IntTools_FaceFace::TolReal()* and *IntTools_FaceFace::TolReached2d()* have been removed.
* Intersection tolerances of the curve can be obtained from the curve itself:
- *IntTools_Curve::Tolerance()* - returns the valid tolerance for the curve;
- *IntTools_Curve::TangentialTolerance()* - returns the tangential tolerance, which reflects the size of the common between faces.
* 2d tolerance (*IntTools_FaceFace::TolReached2d()*) has been completely removed from the algorithm as unused.

OCCT 3D Viewer, in general, supports wide range of graphics hardware - from very old to new.
Therefore, if you observe some unexpected visual issues - first check for OpenGL driver update (or firmware update in case of mobile platforms);
but beware that driver update might also come with new bugs.
Don't forget to report these bugs to vendors.
