Hi all.

I've just finished a set of macros for use in my possible IRTC entry (running
out of time... don't even have basic scene set... uh oh).  I want to be able to
"grow" an object.  That is, expand it by some amount along the normal of all
surfaces, kind of like the grow command in a vector based drawing program.

This little include file does that for the five objects that I could figure out
how to grow.

I'll post a simple example image on p.b.i.

The next question is, can a general method for isosurfaces be had?  I don't
really think so, but I thought I'd ask the question.

Michael
