Geomview is optimized to do polygonal, line or dot rendering which means you'd have to convert your volume data to an object built from say cubes (where each cube is placed at the location of a "1") or alternatively convert to a 3D array of dots and play connect-the-dots to see the edge you're talking about. An alternative would be to use a program specifically designed to do volume rendering, such as "Bob" available from the Army Research Center. Check out the overview of "Bob" with your favorite web viewer by URLing over to: http://www.arc.umn.edu/html/gvl-software/bob.html The program runs only on SGI's and you'd better have a fast graphics board (like VGX) or it will be extremely slow. You can get the program via ftp from ftp.arc.umn.edu Hope this helps. If you have any more questions feel free to write us again. Daeron Meyer daeron at geom.umn.edu
