Updated documentation
Updated samples
ShapeAnalysis::OuterWire(): fixed missed logic when TopoDS_Iterator notifies about more objects to iterate, but there are only vertices and no additional wires at all.
Add parameter EnableControlSurfaceDeflectionAllSurfaces to IMeshTools_Parameters enabling possibility to optimize mesh even on analytical surfaces;
Add corresponding parameter -surf_def_all to incmesh Draw command.
Increase minimum number of discretization points by one explicitly on each iteration of model healer to cover cases degenerated to line (for cases when face consists of 2 edges only).
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.
* Avoid crash in BRepBuilderAPI_GTransform algorithm. The crash in BRepBuilder_Transform has been solved by 0032716.

* 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).
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.
incmesh - added -prs option to use StdPrs_ToolTriangulatedShape::GetDeflection() as meshing parameters.
vdisplay, XDisplay - added -autoTriangulation option to manage meshing behavior before displaying a shape.
trinfo - added output of meshing parameters.

BRepTools/BRepTools_NurbsConvertModification.cxx -
Checking domain of 2dCurves if surfaces are periodic is improved
tests/bugs/moddata_3/bug32557 - test case added
Method EstimateDeflection has been added to BRepLib in order to check and update value of deflection provided by Poly_Triangulation;
Introduction of Poly_TriangulationParameters intended to keep info about initial parameters of mesh stored by Poly_Triangulation;
BRepMesh stores user-specified parameters to Poly_Triangulation via Poly_TriangulationParameters;
Prefer initial parameters of mesh generator stored in Poly_Triangulation during check of mesh consistency.
1) Extend Poly_Triangulation by mesh purpose, possibility to be cleared and late-load deferred data interfaces.
2) Update BRep_TFace to store list of triangulations istead of single one. And also active one. Update getter and setter of single triangulation and add new methods to interaction with whole triangulations list.
3) Update BRep_Tool to get single triangulation of face according to the input mesh purpose or whole triangulations list.
4) Update BRep_Builder to make face by not only single triangulation but whole triangulations list with specified active one.
5) Add new methods to BRepTools to interact with shape triangulations (Load/Unload/Activate/LoadAll/UnloadAllTriangulation(s))
6) Add new 'tlateload'command for shape to load/unload/activate triangulations.
7) Update 'trinfo' command by '-lods' options to print detailaed information about LODs of this shape
8) Support empty triangulations by selection. Use bounding box selection in this case.
9) Add new 'outdisplist' option to XDispaly command to print list of displayed objects to output variable but not to theDI
10) Add new '-noecho' option to vdisplay command to skip printing of displayed objects to theDI
11) Create new RWMesh_TriangulationSource as mesh data wrapper for delayed triangulation loading.
12) Create new RWMesh_TriangulationReader as base interface for reading primitive array from the buffer.
13) Cache nodes/triangles number defined in glTF file
14) Use RWMesh_TriangulationSource class as base of RWGltf_GltfLatePrimitiveArray one and RWMesh_TriangulationReader class as base of RWGltf_TriangulationReader one
15) Add possibilty to support of LODs by glTF reader. It is possible to skip data loading and load them later
16) Add new '-skiplateloading' (to skip triangulation loading), '-keeplate' (to keep information about deferred storage to load/unload triangulation later),
'-toprintdebuginfo' (to print additional debug information) options to ReadGltf command
17) Add new test of glTF late loading
- Added comment to the method
- Added Boolean argument indicating the need for a strict
- Extended OCC11758 command in QABugs_19.cxx to verify IsRealValue()
- Updated existing places of IsRealValue() usage in ViewerTest to use new flag
BndLib/BndLib_AddSurface.cxx : algorithm of building bounding box for BSpline surfaces is improved
Test cases are modified according to current state of algorithm
Test case bug31995 added
Added custom meshing core algorithm to generate base mesh using Delabella library,
which can be enabled via IMeshTools_Parameters::MeshAlgo option or CSF_MeshAlgo environment variable.
Do not fill cirles filter upon explicit initialization.
Call base postProcessMesh functionality after initialization of circles in BRepMesh_CustomDelaunayBaseMeshAlgo.
Added Vsprintf() wrapper for vsprintf() preserving C locale.
BRepMesh: Add new mesh parameter *AllowQualityDecrease* which affects the criteria used for checking of the consistency of the existing mesh to new meshing parameters.
So if set to true it will force the meshing of the shape if current deflection strongly vary from the new one, no matter in which side.
BRepTools::Clean: Keep triangulation on non-geometric shapes (faces with no surface or edges with no curves).
GeomConvert_1.cxx:
Creation periodic BSpline surfaces from trimmed periodic surface if trim is boundaries of periodic domain is allowed
BRepTools_NurbsConvertModification.cxx:

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.
Added new parameter KeepSmallEdges to IMeshTools_Parameters allowing to compute min size for each edge locally, depending on the length of particular edge.
Parameter -smalledges now available for incmesh command.
IMeshTools_ModelAlgo and IMeshTools_ModelBuilder have been changed to provide exception protected interfaces for performing the operations.
Protect single Edge/Face discretization methods from raising exceptions to skip broken Edges/Faces and allow mesh construction on the whole model.
1. Approx_ComputeCLine.gxx, Approx_FitAndDivide.hxx, Approx_FitAndDivide2d.hxx, BRepFill_ComputeCLine.hxx
It is base modification, which allows improve performance of approximation with help of Approx_ComputeCLine. The main idea of improvement is using degree selection by inverse order - from maxdegree to mindegree. If tolerance for maxdegree is not reached, there is no sense to make approximation for current number of knots with lower degree, it is necessary to cut parametric interval.
2. ProjLib_ComputeApprox, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ProjectOnPlane
It is additional modification of methods using Approx_ComputeCLine.
Mainly, modifications concern to more optimal choosing parameters for approximation algorithm.
3. BRepCheck_Face
Small improvement of method Intersect(...), which intersects two wires on face.
4. BRepTopAdaptor_FClass2d
Impovement of treatment infinitely narrow faces.
5. ChFi3d/ChFi3d_Builder_6.cxx
Small improvement, which forbids extension of singular boundary of surface.
It was TODO problem in tests/bugs/modalg_7/bug27711_3
6. IntTools_EdgeEdge.cxx
Improvement of performance for cases of searching common parts between line and analytical curve
7. GeomliteTest_CurveCommands.cxx
Adding Draw command fitcurve. This command is analog of approxcurve, but uses Approx_FitAndDivide algorithm.
Mainly to have direct draw command for testing Approx_ComputeCLine.
8. Extrema_ExtElC.cxx
Treatment of case "infinite solutions" for extrema line-ellipse
9. Modification of some tests according to new behavior of algorithm.
10. tests/perf/moddata/bug30435
Test for new improved algorithm.
11. Implementation QAcommand OCC30435 in QABugs_20.cxx used in test bug30435
The previous code has a condition to avoid processing the same faces if the face has a location.
The similar condition should be applied during the edges processing.
If not doing this, in the previous implementation, IMeshData_Edge instances are created for all edges(even located), but edges of faces located are not filled with curves.
As a result we had wrong local selection of edges.
Limit addition of edges to data model by ones with unique TShape and location using edges map already available in BRepMesh_ShapeVisitor.
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.
OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).
vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.
ViewerTest::ParseColor() now parses RGBA color.
Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
