draw_test_harness.md - description of new options in Draw commands
AppDef_BSplineCompute.hxx, BRepApprox_TheComputeLineOfApprox.hxx, GeomInt_TheComputeLineOfWLApprox.hxx, Approx_BSplComputeLine.gxx - implementation of method SetPeriodic(...) and implementation periodic boundary conditions for multiline in order to get periodic multicurve.
GeomAPI_PointsToBSplineSurface.hxx, GeomAPI_PointsToBSplineSurface.cxx - adding new parameter for methods Init(...) and Interpolate(...), implementation of building periodic tangents for first and last AppDef_MultiPointConstraint of multiline for U direction of surface.
GeometryTest_APICommands.cxx - implementation of new functionality in Draw command surfapp and surfint
GeomFill_NSections.cxx
Fixing problem with bugs modalg_3 bug606_2
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.
Small correction of shape names for issue CR27252
Test case for issue 28210
Small correction of test case for issue 28210
1. Intersection curve was not bounded by faces domain. It was the reason of big edge tolerance. This problem has been fixed.
2. Interface bopcurves DRAW-command has been changed in order to make possible to reproduce intersection problem.
Creation of test case for this issue.
