Thanks Ron.

Got another question for you.  In a triangle mesh, only the x,y,z
coordinates of the verticies are given for each triangle.  How does povray
establish the numbering of the associated verticies?  I need to find a good
way to asign numerical indicies to verticies so I can specify a triangle by
giving its vertex numbers (VRML requires this information).  Any suggestions
how I can do this?

Thanks.
