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.
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.
Modification of checking points for the state "ON" in BRepClass_Intersector.cxx;
Added the test for this ticket;
test case lowalgos/classifier/bug377: BAD -> OK
Make XCAFDoc_Editor::RescaleGeometry to pass the flag theCopyMesh==true
in call to BRepBuilderAPI_Transform::Perform.
Correct the help of the command XRescaleGeometry.
* Avoid crash in BRepBuilderAPI_GTransform algorithm. The crash in BRepBuilder_Transform has been solved by 0032716.
* Move copying modifier to BRepTools package.
* Implement copying of triangulation in BRepTools_NurbsConvertModification.
* Implement transformation of a triangulation in BRepTools_GTrsfModification.
* Update test case bugs/mesh/bug22778 to clean the triangulation after conversion to NURBS (reproduce the same behavior as before).
* Implement methods for copying tessellation to BRepTools_TrsfModification to keep the triangulation during transformation.
* Add tests to reproduce the problem.
Improved the processing for the case where Failure flag for the meshing face is set. Specific tests added.
Check triangulation consistency even for shapes with problematic topology given that they are suitable for keeping it.
Get rid of strange code: preliminary check of self-intersections is made on a polygonal representation of a curve, it is able to find possible intersections, but after that it filter out segments neighbor to the pair of non-intersected segments.
Test case de step_4 I1 has been marked BAD, because the self-intersection is treated correctly, but the projection algorithm generates such crooked 2D curve.
Reference data in test cases heal split_angle_advanced ZA5 and ZA6 has been updated, because those shapes have self-intersected edges, which are being detected now.
Fix affects BFGS optimization methods by checking convergence as the first step on each iteration. FRPR works well, but it is updated as well since its logic potentially dangerous.
When creating a fillet, num is calculated via ChFi3d_IndexOfSurfData. If it
returns just the number of entries in surfdata, it can happen that this
value becomes invalid when handling the case "two faces common to the edge
are found". When both components are on an arc, there will be num removed
from the surfdata.
num would then be larger than the number of entries surfdata. The derived
num1 is therefore also incorrect. The subsequent usage of this
value will either:
* Debug build: cause an out of bounds exception in ChangeValue
(`SeqFil.ChangeValue(num)`)
* Release build: cause a segfault when retrieving it via index num1
(`SeqFil(num1)`)
num + num1 must be recalculated after the deletion happens to correctly
calculate the fillet.

The PerformIntersectionAtEnd code is currently not handling all the faces
correctly. If it retrieves Face[0] as F, it can happen that the previously
ran code didn't actually retrieve any faces in this array at all.
For example when:
* "if (nface==3)" is true
- "if (!findonf1)" is true (doesn't assign any faces to this array)
- "if (!findonf2)" is true (doesn't assign any faces to this array)
- "if (state == ChFiDS_OnSame)" is not true (because it is
ChFiDS_AllSame)
- "if (findonf1 && !isOnSame1)" cannot be true (see above, but would
handle faces)
- "if (findonf2 && !isOnSame2)" cannot be true (see above, but would
handle faces)
- "if (isOnSame2)" is false (but would also handle faces)
Since no faces were assigned here, F would be a NULL face. As result, the
function will crash when trying to access the Surface behind the face via
`BRep_Tool::Surface(F);`.
While the best approach would be to identify the implementation bug in the
algorithm behind PerformIntersectionAtEnd, a check + exception is used
instead because the actual algorithm is not known.

The ChFi3d_IsInFront code is currently not handling all the combinations
correctly. For example, if `if(fd1->IndexOfS2() == fd2->IndexOfS2())` is
true, it can happen that the `TopoDS::Face(DStr.Shape(fd1->Index(jf1)))`
returns a Face with entity == NULL. The subsequent usage of this NULL face
in `BRep_Tool::Parameters( Vtx, face )` will then cause a segfault.
While the best approach would be to identify the implementation bug in the
algorithm behind PChFi3d_IsInFron, a check + exception is used instead
because the actual algorithm is not known.

Added new option '-C' with possibility to set value of Angular and linear tolerances to 'mksweep' command to correct input spine by merging smooth connected neighboring edges
Problem: the complete surface of the torus is not stored correctly in STEP format due to the fact that the edges are not properly ordered.
Change: added a mode for reordering edges in the wire with simultaneous use of 2d and 3d information (ShapeAnalysis_WireOrder). The new mode is used for torus-like surfaces before saving to STEP format.
Result: Torus correctly stored.
Add choosing the intersect point taking into account the tangentCross when prev UEdge and next UEdge has more than one intersect points;
Add exact correction of edge tolerance (it fix problems with edge tolerance on Linux);
Add exact check of edge tolerance in testcase
IntTools/IntTools_BeanFaceIntersector.cxx - calculation of deflection for surface bnd box is added
tests/bugs/modalg_8/bug32942,bug32943,bug32944,bug32945 - new test cases added
Code related to supporting of single SDR for a non-manifold group, which prevents writing all translation results except the first one, is removed.
SDRs with null used representation object are excluded from writing.
1. Modify method IntPatch_ALineToWLine::MakeWLine: add correction of end points of each line on 2 surfaces if an end point is a pole on a surface.
2. Modify method IntPatch_WLine::ComputeVertexParameters: adjust a point on curve to corresponding vertex the following way: set 3D point as the point of the vertex and 2D points as the points of the point on curve.
