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
Intersection of curves and surfaces in HLRBRep is corrected: parametric limits of face are used instead of parametric limits of surface
Building of outlines (Contap_Contour) is corrected: method ComputeCloseLine is now used in all cases.
Correction of HLRBRep_Surface: usage of UVbounds-option
Correction of test cases according to the new behavior.
The following modifications were done for stability:
- Precision::PConfusion() was set as parameter of Classifier instead of 0.0
- Coinciding vertices of outlines are united to exclude neighborhood of common vertex from curve-curve intersection
- Draw command "hlrin3d" was modified to prevent exception
Minor corrections
Corrections of test cases for issue CR27557
- removal of excess interferences in case of simple hiding face
- correct processing of boundary edges coinciding with outlines
- change of API for testing Draw Command
- correction of Draw command "build3d"
- test cases are added.
Linux reference data is changed.
Partially fixed 0027340: Insufficient exact HLR speed
Number of samples in PolyPoly intersection algorithm tuned in each instance of generic class.
Default number of the samples in Geom2dAdaptor is changed according to the Adaptor2d_Curve2d class.
Minimal number of points in case of B-Spline is changed.
Minimal number of samples support is added in intersection algorithms.
