Attached is a five I've successfully used to generate several .df3s
out of csg-able objects - a keyboard, the word POV, a julia fractal, a
torus (with some turbulence makes a really good pipe smoke ring). Just
declare the object you need converted and render an animation. The
object bust fit into the unit box and must be csg-able. Frames must be
of square shape. It takes a lot of tweaking to get a complex object to
fit into the unit cube, but if you have the superpatch, a simple macro
using min_extent and max_extent could do the trick. For now, I hopw
this is useful as is.
