Here is the picture of my Bezier Surface program.
The program made with Delphi and OpenGL. It build a Bezier surface from triangles!
This is my own Bezier calculator, it don't use any special Bezier command. I have
chosed the triangle basis because it is much harder then other. In the program you can
change a lot of things. You can modify the amount of the controll points and the
resolution, pick one ore more of it and move them, rotate, scale, add lights, set
the rendering states like one or two sided linghting, wireframe, flat, shade,
texture map, sphere map, enviroment map, level coloring and you can chose the
backface rendering (standard, transparent, culled)
The program is available at my site : www.zsombor-fritz.net
