f55fe3b3f7 0033149: Mesh - misprint in BRepMesh_NURBSRangeSplitter::computeGrainAndFilterParameters() 2022-10-31 18:08:24 +03:00

a939fd40eb 0031853: Mesh - holes in triangulation with large linear deflection
0030442: Mesh - broken triangulation on pipe shape

Scale down min size parameter for NURBS taking into account its U and V resolution in order to prevent comparison of 2d parameters with 3d value involved in filtering process.

c4ea4ca3d1 0032241: Mesh - wrong shading display of thrusections [regression since OCCT 7.4.0]
0032422: Mesh - Weird rendering
0029641: Mesher produce 'bad' result for extruded spline with given deviation coefficient

Added method BRepMesh_NURBSRangeSplitter::getUndefinedInterval() intended to compute checkpoint parameters for those NURBS surfaces which have no intervals at all. In this case number of poles is used to produce artificial regular grid which can be refined further. Add at least one midpoint for surfaces with one interval and only two poles.

Added BRepMesh_ExtrusionRangeSplitter and BRepMesh_UndefinedRangeSplitter derivatives from BRepMesh_NURBSRangeSplitter intended to handle special cases of extrusion surfaces and general surfaces with undefined parameters.

29263c947e 0031425: Visualization - free Edge has selection sensitivity inconsistent to presentation
BRepTools::Triangulation() has been extended with a new parameter for checking Poly_Polygon3D presense within free Edges.
StdPrs_WFShape::Add() now performs auto-triangulation in the same way as StdPrs_ShadedShape::Add().
StdSelect_BRepSelectionTool::GetEdgeSensitive() now creates Select3D_SensitiveSegment instead of Select3D_SensitiveCurve for tessellated segment.
Select3D_SensitiveSegment default sensitivity factor has been changed to 3 pixels to match Select3D_SensitiveCurve.

Test case bug23625_1, added workaround for out-of-range crash in HLRBRep_PolyAlgo on re-triangulated shape.

8c186dad9b 0025044: BRepMesh tweaks - treatments for degenerated and tiny faces
BRepMesh_ModelHealer - recognize a small face with 1 wire and 2 small edges as a face for refinement.
BRepMesh_DefaultRangeSplinner - reduce tolerance on tiny faces to improve the meshing results.

Added new test cases: bugs mesh bug25044_*.
Existing test cases updated to reflect improvements.

3977d18aca 0030286: Cover polygonal HLR algorithm by regression tests
New folder "hlr" with subfolders "exact_hlr" and "poly_hlr" has been created.
Draw command "vcomputehlr" has been corrected.
QA command "OCC27341" has been deleted as "vcomputehlr" does its job.
