[comp.graphics] 3-d contouring code

rhl@astro.Princeton.EDU (Robert Lupton (the Good)) (08/03/90)

I have a user who would like to display some data that is a function
of 3 coordinates (2 angles and a velocity, if anyone cares) as a
3-dimensional contour image. That is, the data is an intensity 
I(l,b,v), and he can choose some level, say I_0, which then specifies a
surface in 3-D. Is there any public domain stuff that can do this
that runs on a sun? Preferable X11, but sunview would be OK. 

I'll take anything, from wireframe to fully raytraced.

Speed isn't of great importance (but would help...)
