| Summary | 0023409: Tricheck command doesn't report problem when triangulation has unexpected holes | ||||
| Description | tricheck should be improved to detect holes in the triangulation. This problem is described in 0023167 by abv: I noticed another problem: neither incmesh nor tricheck nor trinfo commands in DRAW notice the problem in triangulation when it existed. I have attached file bug23167_f397.brep which is face 397 from the STEP file coming with bug report, with triangulation computed by previous snapshot of OCCT (should be similar to that produced by OCCT 6.5.3). Problematic shape from bug 0023167 is attached. | ||||
| Steps To Reproduce | Do in DRAW: restore bug23167_f397.brep a vdisplay a # shape looks bad! axo fit isos a 0 triangles a # free edges can be seen trinfo a tricheck a # no problems are reported -- why? | ||||

Dear EPA, Could you please review the branch CR23409? |

I have no remarks; please test |

Dear Bugmaster, please test the branch CR23409. Now tricheck command indicates a mesh problem if a hole between mesh internal links is detected. For the attached shape result of tricheck is the following: restore bug23167_f397.brep a vinit vsetdispmode 1 vdisplay a # shape looks bad! axo fit isos a 0 triangles a # free edges can be seen tricheck a ## Result of old mesh checking => Not connected mesh inside face 1 tclean a incmesh a 0.01 tricheck a ## Result of new mesh checking => empty, i.e. Ok vdisplay a ## and shape looks good in the viewer |
