New gradient method

Compared to this new gradient computation method, my previous one was silly (but allows nevertheless the "tiger flower", which is not the case of this new method). This new method simply compute decreasing centered subpiece of bezier surface.

Tiger flower

Same as before, except that only one frame is not drawn for two computed.

Reiteration

Same as previous, with changed iteration pattern

Color gradient

Same picture as before, but with some more iterations, and color rendering. Nice indeed.

Some results

Here is a first result with automatically created gradient, but

• some errors appear in bezier surface cut
• the gradient pattern occurs to reflect the way cut is done : may be nice, but it is not what I was expecting
  

Oups

Something's wrong in coord computation. Interesting though

Manual color gradient

Soon more automatic and gradual ... gradient

Daily new

More cutting edges

Playing again.Post them before trying some improved features.

Metart

Just for fun : my class hierarchy. Obviously cleaning is needed though ...
