I think that it is still called Delaunay triangulation (or
N-dimensional Delaunay triangulation).  I'm not sure if that
is what vtkDataSetTriangleFilter uses for images, since
vtkVoxel::Triangulate() provides a direct, efficient method for
generating tetrahedrons from voxels.  You can look at the
vtkDataSetTriangleFilter code to see which method it uses.
