Surface Interpolation


I have irregularly spaced data points on the surface of 3D object.  I
would like to generate a triangle or polygon interpolation of the surface
of the object.  I have successfully used the TWJ Delaunay package for
portions of the object that are uniquely valued in a sectioning plane,
but a would like a more general approach that can handle generic 3D
surfaces.  Has anyone coded the marching cubes algorithm or a 3D Delaunay
triangulation?  I welcome any suggestions or pointers.
