Message-ID: <1991Mar14.234739.15281@athena.mit.edu> Date: 14 Mar 91 23:47:39 GMT Sender: news@athena.mit.edu (News system) Organization: Massachusetts Institute of Technology Lines: 15 Umm, I've never read or posted to either of these groups. What I am looking for is some code to take the function zz = f(x,y,z) and render the 3-D surface which corresponds to this. Ideally, I'd like C-code for a silicon graphics machine. My current technique is to evaluate f(x,y,z) for all discretized (x,y,z) inside of a cube - and to light up a point if : | f(x,y,z) - constant | < Epsilon if you have any ideas - please help. --David Chasman chasman@athena.mit.edu
