I had to prepare little engine to triangulate any flat shapes. It's not ready
for upload (dirty code) but has first outputs. First pictures present shape
(rounded rectangle) after triangulation but without triangles. Second picture
shows grouped triangles - regular and changed. I plan to export this
triangulated stuff in PCM file format. Engine was made as POV script.
Any comments ?

Look interesting, but what is PCM? Why not plain old POV/text?

I'm not sure about the practical purpose, but it looks interesting.

practical purpose ? animation of flying leafs, cards, walking carpet etc.
1. scan complicated shape - for example leaf
2. triangulate it with inside/outside function via eval_pigment on image_map
3. deform it much complicated way than patches
4. use compressed mesh package by Chris Colefax and Warp to optimize result for
complicated scenes
5. use scaned image_map via uv_mapping
6. trace scene
is it good enough purpose ?

Thanks, PCM is ... http://www.geocities.com/SiliconValley/Lakes/1434/pcm.html
> Why not plain old POV/text?
but ... it is plain old POV/text available via macro :-)

Yes, that sounds feasible, right now i probably would use a patch or
heightfield with partly transparent texture for this purpose.
