eSELF_INTERSECTIONS = (1 << 2), //!< problematic: The surface of the resulting mesh won't match exactly at locations of self-intersections. The tetmesh might be connected at self-intersections even if the input triangle mesh is not

eINCONSISTENT_TRIANGLE_ORIENTATION = (1 << 3), //!< invalid: It is not possible to distinguish what is inside and outside of the mesh. If there are no self-intersections and not edges shared by more than two triangles, a call to makeTriOrientationConsistent can fix this. Without fixing it, the output from the tetmesher will be incorrect
|

|
eCONTAINS_ACUTE_ANGLED_TRIANGLES = (1 << 4), //!< problematic: An ideal mesh for a softbody has triangles with similar angles and evenly distributed vertices. Acute angles can be handled but might lead to a poor quality tetmesh.

eEDGE_SHARED_BY_MORE_THAN_TWO_TRIANGLES = (1 << 5), //!< problematic: Border case of a self-intersecting mesh. The tetmesh might not match the surace exactly near such edges.

|
|
eCONTAINS_DUPLICATE_POINTS = (1 << 6), //!< ok: Duplicate points can be handled by the mesher without problems. The resulting tetmesh will only make use of first unique point that is found, duplicate points will get mapped to that unique point in the tetmesh. Therefore the tetmesh can contain points that are not accessed by a tet.
