Non-convex facet. (tessellation)

Recommended Posts

Non-convex facet. I need to render in OpenGL Viewer - object, which consist of non-convex facets (and additionally this facets contain "holes"). Facets and their holes are flat PolyLines (and I need fill their with solid color or texture). Will I be able to do this without triangulation algorithm? What are you recommend me to read about this topic? .................................................... I have found article in OpenGL FAQ but it''s not clear for me. 4.040 How do I use GLU tessellation routines? Could you please to point me to additional articles about this theme (better with source code)? -- Best Regards Taras e-mail : tr@os-it.com

You''ll probably need a good triangulation system for that.

Look at: http://www.geom.umn.edu/software/cglist/

I have a good and stable triangulator for concave polys (with holes) using an extended Seidel-algorithm, but I can''t find it on the net anymore, the links are dead. If you can''t find anything else, I can email it to you.
