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.
Method IntWalk_PWalking::ExtendLineInCommonZone(...) now is not called if the already found intersection point is on surface boundary.
As result, the intersection line going along any boundary will never be extended. It is appropriate for high-level OCCT-algorithm because they will take the boundary (not computed line) as intersection result.
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).
Fixed the Toroidal surface recognition;
The test case bugs/moddata_1/bug22296: the result is a torus with parameters: u [0, 2*PI], v [PI, 3*PI];
The test case bugs/modalg_5/bug23954: BAD -> OK.
With enabled flag BUILD_USE_PCH we get an error of compilation of TKService:
1>Image_VideoRecorder.obj :
error LNK2019:
unresolved external symbol
"int __cdecl av_strerror(int,char *,unsigned __int64)"

1>Media_FormatContext.obj :
error LNK2001:

And many other similar errors. Similar errors occures in some other projects too:
TKService
TKOpenGl
TKOpenGles
TKXCAF
TKXDEDRAW
TKDFBrowser
TKMessageModel

TKShapeView
TKTInspector

TKVInspector
TKView
Proposed solution: turn off cotire from targets, whose compilation cause error while applying cotire tool.
In this ticket migration to cotire 1.8.1 (from 1.7.9) is done.
COTIRE_PREFIX_HEADER_IGNORE_PATH does not apply here, because its employing
causes some errors in 3rdparty libraries (for example, in TKService project).
Projects (TKDFBrowser TKMessageModel TKMessageView TKShapeView TKTInspector TKTreeModel TKVInspector TKView)
which use Qt may be proceeded by cotire tool, but after fixing a bug of cotire:

After emploing intel oneTBB of version 2021.5 on NEXT platforms arises error on OCC Pr.:
`
*/ld: */libfreetype.a(truetype.o): relocation R_X86_64_PC32 against symbol `TT_RunIns' can not be used when making a shared object; recompile with -fPIC
*/ld: final link failed: bad value
`
Proposed solution: linking with shared object of libfreetype, rather than with archive library.
Despite that error occurred only in OCC Pr., it is worth to accept changes for OCCT too.
Previous approach do not taking into account, that oneTBB library may be installed in the system folder
on Linux. So, solve the problem it is proposed to employ find_package utility, that works great
as on Windows, as on Linux.
Problem: From the point of view of the STEP format (and others), it is allowed
to describe a face on a surface with natural boundaries (torus, sphere) without
specifying these boundaries. Thus, a face on a closed surface and containing
an inner wire (or several) is correctly defined and describes a face with a
cutout defined by this wire. At the same time, there is a function
(ShapeFix_Face::FixOrientation) in the ShapeHealing procedure that corrects the
orientation of the wires, and it starts before the function of adding natural
boundaries (ShapeFix_Face::FixAddNaturalBound). There are many shapes that have
incorrectly oriented wires and this procedure successfully heals them, but on a
correctly specified face with single inner wire on closed surface, we do not get
the entire surface with a cutout, but a part of the surface defined by the wire.
This fix is intended to resolve this ambiguity.
Change:
1. Added function isNeedAddNaturalBound that returns TRUE if face needs to add
natural bounds.
2. Corrected condition in FixOrientation to ignoring faces that needs to add
natural bounds.
3. For tests in which one wire was incorrectly oriented on a closed surface,
flag AddNaturalBound was disabled.
5. Test with cutout from torus was created: bugs step bug28414.
Result: By default, it is correct to add natural boundaries, because this case
is correct from the point of view of the STEP format and others.
Problem: There is no possibility to change shape healing options from DRAW without rewriting resource file.
Change: Shape healing parameters from STEP and IGES resource files were duplicated to InterfaceStatic. Resource manager initialize from InterfaceStatic if resource file name is empty.
Result: User can operationally change shape healing parameters from DRAW command using "param" command.
Currently directory containing tbb 3rdparty installation should match the template tbb*.
But after using oneTbb of version 2021.5 standard installation directory is onetbb*.
So, for this 3rdparty modify searching template.
Adapt test case, the problem is not reproduced any more.
Problem is fixed by the commit: 46478ffe32cfca537a35b744700e082f59ec4c4c (0030008: BRepMesh does not respect angular deflection in internal area of bspline surface)
MSVC 2022/c++20.
After employed c++20 language standard errors of compilation in intel oneTBB occurred.
To get rid of compilation errors proposed moving on actual (2021.5.0) intel oneTBB occ products and occt.
After migration errors of compilation of TKernel and TMath have been occurred...
...Error occurred if using c++20 standard with new oneTBB 2021.5.0.
The error was:
Error C2672 'tbb::v1::parallel_for_each': no matching overloaded function found TKernel
could be 'void tbb::detail::d2::parallel_for_each(Iterator,Iterator,const Body &)' TKernel
'tbb::detail::d2::parallel_for_each': the associated constraints are not satisfied TKernel
Note, that if we use c++14 or c++17, all ok, error does not occures.
To solve the problem, i have to modify `UniversalIterator` class:
`value_type` instead `UniversalIterator` converted to `IteratorInterface*`
`pointer` = `reference` = `value_type`
Method `DownCast` moved into `FunctorInterface` abstract class.
argument `UniversalIterator& item` of the unary fuctions converted to `IteratorInterface*`.
The proposed solution removes compilation error.
Affected projects: TKernel, TMath
Affected sources: src/OSD/OSD_Parallel.hxx, src/OSD/OSD_Parallel_Threads.cxx
Affected classes: class OSD_Parallel, OSD_Parallel::UniversalIterator, OSD_Parallel::FunctorInterface, OSD_Parallel::FunctorWrapperIter, OSD_Parallel:;FunctorWrapperInt.
- ShapeFix_Face::FixMissingSeam method is fixed in order to handle degenerated torus
- Calculation of degenerated torus bounding box is fixed

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.
Extend "proximity" command to be able to compute the proximity value;
Implement classes for calculate proximity value between two shapes;
Add possibility to set up the number of sample points for the input shapes;
Add tests lowalgos/proximity.
Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
