1. Approx_ComputeCLine.gxx, Approx_FitAndDivide.hxx, Approx_FitAndDivide2d.hxx, BRepFill_ComputeCLine.hxx
It is base modification, which allows improve performance of approximation with help of Approx_ComputeCLine. The main idea of improvement is using degree selection by inverse order - from maxdegree to mindegree. If tolerance for maxdegree is not reached, there is no sense to make approximation for current number of knots with lower degree, it is necessary to cut parametric interval.
2. ProjLib_ComputeApprox, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ProjectOnPlane
It is additional modification of methods using Approx_ComputeCLine.
Mainly, modifications concern to more optimal choosing parameters for approximation algorithm.
3. BRepCheck_Face
Small improvement of method Intersect(...), which intersects two wires on face.
4. BRepTopAdaptor_FClass2d
Impovement of treatment infinitely narrow faces.
5. ChFi3d/ChFi3d_Builder_6.cxx
Small improvement, which forbids extension of singular boundary of surface.
It was TODO problem in tests/bugs/modalg_7/bug27711_3
6. IntTools_EdgeEdge.cxx
Improvement of performance for cases of searching common parts between line and analytical curve
7. GeomliteTest_CurveCommands.cxx
Adding Draw command fitcurve. This command is analog of approxcurve, but uses Approx_FitAndDivide algorithm.
Mainly to have direct draw command for testing Approx_ComputeCLine.
8. Extrema_ExtElC.cxx
Treatment of case "infinite solutions" for extrema line-ellipse
9. Modification of some tests according to new behavior of algorithm.
10. tests/perf/moddata/bug30435
Test for new improved algorithm.
11. Implementation QAcommand OCC30435 in QABugs_20.cxx used in test bug30435
1. Extrema algorithm calls Curve-surface intersector. This intersector returns flag about infinite solution (in spite of extrema's returning not-parallel status correctly - axes of considered cylinder and circle are not parallel). In this case, attempt of obtaining number of intersection points leads to exception.
So, the fix adds check of infinite solution after the intersection algorithm.
2. The methods IsDone(), IsParallel(), NbExt(), SquareDistance() and Points() (of Extrema_* classes) have been corrected to make them consistent to the documentation.
3. Revision of some Extrema_* classes has been made in order to avoid places with uninitialized variables.
4. Currently Extrema does not store any points in case when the arguments are parallel. It stores the distance only.
5. Some cases on Extrema-algo have been moved from "fclasses"-group to "modalg"-group.
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.
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.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
