Hi,

Would you help me to solve next task:

Let’s have surface of revolution (it is created by means of rotating the arbitrary

curve around the axis). It’s simple to visualisate such body. Problem is, that

this body can be trimmed in a same way

like the nurbs surfaces are.

I’d like make it as simple as possible (I’d like to avoid mathematics and intersections computing). Has OpenGL tools for solving this? To define a surface by means of grid of 3d points and then to use trimming?

Thanks for your opinions.

Adrian Helcman.
