I''m still searching the method to breaking a surface (sphere, cube, an another triangle,...) but i couldn''t reach any scientific text. who knows something about this transformation? Regards Ozan Eren Bilgen Webmaster of Galatasaray University, Turkey www.gsu.edu.tr

Assuming you have a planar convex surface, you can just iterate CCW around the polygon taking three points at a time and making a triangle and removing the middle point from your loop. Keep that up until you have a triangle left.

Cubes are easy just split each side.

Spheres... check your math resources, there are a finite number of regualr spheres that can be made from triangles and squares ( ie soccer ball, dice, ... ).

Good luck.
