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 ?
