The reason of the bug is bad start points on surfaces, which are used by searching roots algorithm as start points for iteration process. Starting with these points algorithm for searching roots of set of equations cannot reach correct root. To find correct start points increasing number of sampling points is applied.
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
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. 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.
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.
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. 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.
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
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 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.
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.
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.
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
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
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.
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.
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").
Creation of test case for issues #27221 an #27252.
Adjusting some test cases according to their new behavior.
Correction according to the last remarks.
