   Well, the oft-quoted article 


@Article{LC:MCubes,
  author =      "W. Lorenson and H. Cline",
  title =       "Marching Cubes: A High Resolution 3D 
                 Surface Construction Algorithm"
  journal =     siggraph,
  year =        1987,
  volume =      21,
  number =      4,
  pages =       "163--169"
}


   SAYS it is the Marching Cubes algorithm.  The authors are from GE. 
 I guess they spilled a company secret? More likely you refer to some 
 tweaked version of the algorithm. Big deal. People just want a working
 version of the PUBLISHED algorithm. 

   There are several available implementations of the algorithm described
 in the above article. 

   Trying to redefine the "Marching Cubes Algorithm" as something 
 internal to GE is not helpful.

   PS I have several implementations of Marching Cubes. One is currently
   ftp`able from titan.rice.edu (128.42.1.30) in directory "incoming",
