Cutting edge 2

Just varying the motif. I was just wondering if arbitrary drawing on bezier surface were not analogous to curve spaces in physics ... Need to experiment this.

Cutting edge

Still generalizing bezier shape patching. New algo, by considering :

• a bezier surface defined by a close four-parts bezier curve
• a generalized 2D coord system can be defined on this surface, coord being between 0.0 and 1.0
• algo can then compute a sub surface defined by two "points" of the previous bezier surface

Thus can be defined and computed the image iterated form :

• the bezier surface is defined by a pic bezier, completed to be closed
• four sub-surfaces are computed, from top to bottom
