WebMesh properties¶. A triangle mesh has several properties that can be tested with Open3D. One important property is the manifold property, where we can test the triangle mesh if it is edge manifold is_edge_manifold and if it is is_vertex_manifold.A triangle mesh is edge manifold, if each edge is bounding either one or two triangles.
