Precision used to consider B-Spline knots identical is restricted to be not less than Precision::PConfusion() in Geom2d_BSplineCurve::Segment().
Affected tests updated (improvements)
Test case for issue CR25971
1. Eliminated exception after conversion non-rational B-spline to rational
2. Implemented DRAW command setweight to change weights of B-spline
3. Test cases were added
Implemented additional flag into Geom_TrimmedCurve to adjust or not the periodic curve inside the first period.
API of Geom2d_TrimmedCurve is changed according to Geom_TrimmedCurve.
Test-case for issue #24411
Sometimes curve or surface, which is defined as C0, has continuity G1 or above. Offset can be built from these shapes.
Therefore, this extended checking was added into SetBasisCurve and SetBasisSurface methods.
Main changes in function BRepOffset_Tool::ExtentFace(...):
* "return" is added if intersection (in 2D-space) between two edges in a face cannot be found.
Basis curve/surface continuity value found (if G1-checking is OK) is set up as BasisContinuity (see myBasisCurveContinuity and myBasisSurfContinuity members which is returned by GetBasisCurveContinuity and GetBasisSurfContinuity() methods). This fact is used in Geom2dAdaptor and in GeomAdaptor classes.
Possibility is entered, which allows for basis elements of offset curve/surface to avoid of C0-checking.
Test cases were changed according to their new behavior.
Test-cases for issue #25124
Redundant keyword 'mutable' removed in CDL files.
In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed.
Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.
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.
1. Approximation of derivative (by Taylor-series and by three points).
2. Some methods (Degree(), GetType(), D0(), D3(), DN()) are added.
3. Getting of subInterval's boundaries.
4. Algorithm for checking if 1st derivative is equal to zero is amended.
5. Cases are controlled when extrema or Project point do not exist.
6. GetNormal() function for gp_Vec2d was added.
7. Computing of Value, D0, D1, D2 and D3 for offset curves was changed.
8. Limitation of tolerance for derivative computing was added.
9. Methods for computing trihedron in singularity point are added.
10. Test tests/bugs/moddata_3/bug23706 is added.
11. Restriction on the LastParameter for visualization of 3-D curves. Calling PlotCurve(...) function for last interval.
12. LProp package is modified for tangent computing in singularity point (LProp_CLProps, LProp_SLProps).
13. Added test cases for issue.
Deleting bad test cases for this fix
Add a checking into files Geom_OffsetSurface.cxx, Geom_OffsetCurve.cxx, Geom2d_OffsetCurve.cxx , which try to make continuity of bspline surfaces and curves more than C0 to build offset.
Delete duplicate code and checkings
Prevent change of offset curve / surface when exception is raised due to attempt to set new C0 basis curve / surface
Added new QA command OCC23683. Added test case bugs/moddata_3/bug23683
Internal cache in classes implementing b-spline curves and surface in Geom and Geom2d packages is protected from possible concurrency by mutex (added as a class field in each instance).
