getHullFaces

public int[] getHullFaces()

getTets

public int[] getTets()

Returns the vertex indices of all the tetrahedra in this tessallation. If idxs is the array returned by this method, then the length of idxs is four times the number of tetrahedra, with the vertex indices of the first tetrahedron given by idxs[0], idxs[1], idxs[2], and idxs[3], etc.

The vertices are ordered such that if v0 is the first vertex, v1, v2, and v3 are arranged counter-clockwise about the outward-facing normal of their face.

Returns:

vertices for the tetrahedra in this tessellation.
