| Summary | 0024938: BRepMesh_IncrementalMesh hangs | ||||
| Description | BRepMesh_IncrementalMesh never finishes meshing the provided shape. The method 'checkWiresIntersection' in BRepMeh_Classifier.cxx i a recursive call changes the loop constraints and the loop never finishes. | ||||
| Steps To Reproduce | # Draw reproducer pload ALL restore 27773.brep a tclean a incmesh a 1.5 -relative # initial C++ code for reproducing of the problem TopoDS_Shape aShape; BRep_Builder aBuilder; Standard_Boolean result = BRepTools::Read(aShape, "27773.brep", aBuilder); BRepMesh_IncrementalMesh M(aShape, 1.5, Standard_True, 0.5); | ||||

Oleg, please consider extending command incmesh in DRAW by parameters allowing to specify relative deflection mode and angular deflection |
|
|
Dear Bugmaster, Reported problem is not reproduced on current master, BRepMesh does not fall into infinite recursion. Please create corresponding test case. |

Test case: bugs mesh bug24938 - OK http://occt-tests/24938-linux/bugs/mesh/bug24938.html http://occt-tests/24938-linux-debug/bugs/mesh/bug24938.html http://occt-tests/24938-wnt/bugs/mesh/bug24938.html http://occt-tests/24938-wnt-debug/bugs/mesh/bug24938.html please, review. |

Dear Andrey, could you please add check for number of triangles and nodes (please use "trinfo" command) and if they are zeros, notify about mesh problem (should be suppressed by TODOs) to mark this issue as problematic. I also propose to display shape in shading, i.e. to add command "vsetdispmode 1". Currently, viewer should be empty as far as shape does not contain mesh, however in case if this problem will be resolved image difference will notify about changes. |
