- 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which might provide outdated variable value cached by C runtime library.
~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.
