Function is_delaunay_raw

python/pymesh/meshutils/voxel_utils.py:28–42

Compute whether each tet is strictly locally Delaunay, cospherical or not locally Delaunay. Args: vertices (``numpy.ndarray``): n by 3 matrix representing vertices. tets (``numpy.ndarray``): m by 4 matrix of vertex indices representing tets. Returns: A list of

(vertices, tets)

    return PyMesh.get_tet_orientations(mesh.vertices, mesh.voxels)

    Returns:
        A list of m floats representing result for each tet:
            * 1 => tet is strictly locally Delaunay.
            * 0 => tet is cospherical with an adjacent tet.
            * 1 => tet is not locally Delaunay.
