with http://www.kansas.edu...), for Macs and PC's (Unix as well?).
Otherwise, I have direvt experience with Fortner (formerly Spyglass)
Transform which I believe to be a superb package. Both softwares have edu
On Transform, I displayed displacement data collected from faults (i.e. I
had the relative grid wihin which I had my value points).. using the 3D
surfave contouring. It works very well, you cvan manipulate colors
on-the-fly, change perspective... and all of thius on a relatively normal
Mac (Quadra 800, 24 megs of Ram). You may try with http://www.fortner.com.
