| Summary | 0024051: Voxel_FastConverter::Convert / ConvertUsingSAT - problems in multithreaded scenario (2) | ||||
| Description | I observe strange behaviour when converting a shape using Voxel_FastConverter. For some shapes and on some occasions (multi-threaded conversion to voxels but not every time though) I get the voxels as on attached pictures (problem can be seen on the vertical face). Could this loop in Voxel_FastConverter::Convert: TopExp_Explorer expl(myShape, TopAbs_FACE); for (; expl.More(); expl.Next()) cause the problem? | ||||
| Steps To Reproduce | TopoDS_Shape shape = BRepPrimAPI_MakeBox(gp_Pnt(5, 10, 10), 10, 20, 30); Standard_Integer nbx = 200, nby = 200, nbz = 200; Voxel_BoolDS theVoxels(-50,-50,-30, 100, 100, 100, nbx, nby, nbz); Voxel_BoolDS theVoxels1(-50,-50,-30, 100, 100, 100, nbx, nby, nbz); Standard_Integer nbThreads = 5; Voxel_PreciseConverter fcp(shape, theVoxels, deflection, nbx, nby, nbz, nbThreads, Standard_True); #pragma omp parallel for for(int i = 0; i < nbThreads; i++) fcp.ConvertUsingSAT(progress, i+1); | ||||
