      Implicit Surface Models (ISM)
      -----------------------------
      - commonly called blobby models (Blinn), 
        soft objects (Wyvill), and metaballs (Nishimura)    
        (Some might argue subtle differences but most don't;
        they're pretty much used synonomously.) 

   (1) Good main reference for ISM

   "An Introduction to to Implicit Surfaces", Jule Bloomenthal (Ed.),
   Chandrajit Bajaj, Jim Blinn, Marie-Paule Cari-Gascuel, Alyn
   Rockwood, and Brian Wyvill, Morgan Kaufmann Publishers Inc.,
   San Francisco, CA, 1997. ISBN 1-55860-233-X

       - good introduction with pointers to original research work,          
         details, and applications
       - based Siggraph course notes from a recent Siggraph conference


   (2) "The Implicit Site" - main web site for ISM 
                           - (references, code, research, contacts)

       (This would be a good first step before (1) and (2)
