Visualize trimmed Quadrics

Hi all,
I’m new to OpenGL.
I do have a CSG solid described by trimmed quadrics to display. From the OpenGL documentation looks like only trimmed NURBS can be displayed.

For instance I do have a cylinder cutted by a plane, how can I display the cutted cylinder?

Any suggestion?


What about trianglelation? Cutting by a plane can be done by user clipping planes. But this is more for dynamic stuff.
