Summary0023106: BRepMesh_IncrementalMesh returns wrong status
DescriptionBRepMesh_IncrementalMesh algorithm returns wrong status (== 0 - No Error) in spite of internal exception raised by the algorithm.
Steps To ReproduceDraw reproducer.
> pload ALL
> restore face_0triangles.brep s
> checkshape s
> incmesh s 0.1 ## <<== exception
# Meshing statuses: NoError
# Nevertheless the algorithm raises Standard_OutOfRange exception.
> trinfo s

This shape contains 0 triangles.
                    0 nodes.
Maximal deflection 0
Additional information
and documentation updates		The following changes are made in context of this issue:

- storing of intermediate structures to the shapes in BRepMesh_FastDiscret and their restoring in BRepMesh_FastDiscretFace has been eliminated. Common data structures are moved to BRepMesh_FaceAttribute;

- procedures that fill data structures using existing triangulation as well as a newly created one are unified. Corresponding tools are isolated within BRepMesh_EdgeTessellationExtractor and BRepMesh_EdgeTessellator classes;

- code duplications are removed from BRepMesh_FastDiscret and BRepMesh_FastDiscretFace;

- mutexes are removed from BRepMesh_FastDiscret and BRepMesh_FastDiscretFace due to division of data structures on shared and local ones;

- resulting triangulation is stored within a single place in BRepMesh_IncrementalMesh class;

- BRepMesh_Delaun: redundant flag isPositive is removed due to the face orientation is always forward;
TagsNo tags attached.

 DC,

I propose the following changes to be implemented within current issue:

1) remove .cdl declaration for BRepMesh_FaceAttribute and start using exported header file;
2) in BRepMesh_FaceAttribute introduce reference to BRepMesh_FastDiscret::myFacestate and use it in thread safe mode for setting necessary status in BRepMesh_FastDiscretFace;
3) store myVertices, myInternaledges, myNbLocat, myLocation3d, myLocation2d, myVemap and myStructure directly in BRepMesh_FaceAttribute of corresponding face.
4) remove methods from BRepMesh_FastDiscretFace that perform filling of the structures mentioned above twice and use ones stored in BRepMesh_FaceAttribute.

I suppose that these actions will help to speed up BRepMesh a little and will give further possibility to introduce parallel filling of structures in BRepMesh_FastDiscret.

There are no connections between BRepMesh, data exchange and BOP packages. So reported regressions within modalg_5 and de grids have different whether.

 DC,
Concerning the test report:

Improvements within mesh grid represent real improvements: some faces become triangulated, free nodes and free links notifications dissapeared.

Test mesh standard_mesh C7 - can be treated as an improvement, because number of free links is decreased (from 8 to 2).

Test mesh ... B3 - can also be considered as an improvement due to "free links" notification against "faces without triangulation".

Test mesh ... W5 - improvement, 90 faces without triangulation instead of 91

test mesh ... A5 - shape correctly covered by mesh with specified tolerance, not a regression.

test omf advanced_meshfuse ZD4 - shape "a" contains open wire, BRepMesh unable to produce correct mesh (see screenshot "test omf advanced_meshfuse ZD4.png")

bugs moddata_1 bug22757, bugs vis buc60858 - shapes contains invalid faces to build valid mesh (see screenshot "test bugs vis buc60858.png").

bugs vis bug344 - internal wire of shape processed incorrectly as it was before, not a qulifier.

So, in fact we have only 3 cases raising regressions. However, I treat these ones not as regressions, but as the markers for problems missed during several years. In more detail, each problematic face where triangulation procedure failed is invalid (yes, checkshape says nothing, but shapes are not suitable for building of mesh, see attached screenshots). Before the changes, BRepMesh produced mesh for problematic objects, but it did not reflect the real geometry and it was built somehow or other. However, faces had triangulations and ratio between areas of geometric and tesselated representations were to some extent similar and, therefore, problems were hidden till the nowadays. I think that these problems should be registered as a particular issues in Mantis in furthure.


So, I insist for integration of changes and registering new issues for newly found problems.

We see multiple improvements (both in faces being triangulated where previously failed, and in general look of the mesh which seems to contain less triangles and be more regular), and only four regressions, all on bad shapes.

Thus please consider this issue as tested, and update the affected test cases according to the new state.
