Very cool. Thanks!!! I was still living in the past (man!). I've been
playing with isosurfaces tonight and am having a lot of fun. It opens up a
lot of new possibilities that I hadn't considered before (in particular, I
like the bumps pattern effect on it). Before, I always created my textures
using Photoshop and such. Now, I'll use bozo and wrinkles more and save a
lot of parsing time. I'll also use the function for the height_field (gonna
try that now).
