mesh.Mesh.check_triangle_mesh

Mesh.check_triangle_mesh()

Check whether the triangle mesh is a manifold, orientable and closed.

Returns

manifoldbool

True if the surface mesh is a manifold.

orientablebool

True if the surface mesh is orientable.

closedbool

True if the surface mesh is closed.

minconint

Minimum number of triangles sharing any edge.

maxconint

Maximum number of triangles sharing any edge.

Notes

A Möbius ring is an open non-orientable manifold. A Klein bottle is a closed non-orientable (self-intersecting) manifold.

Examples

>>> from hellotriangle import shapes
