Concave polygon

I am finding examples on using tess. (other than tess.c and tesswind.c) I want to draw concave polygon but I don’t have enough knowledge to do this. Please tell me if u know any web that teaches tess. Thanks.

You might want to have a look at http://nehe.gamedev.net He seems to have a pretty good grasp on openGL, and writes good code. Or take a look at the openGL superbible online (not sure of the url, sorry… maybe http://www.itknowledge.com ??) which has a very good lesson on both tessellation (the computer graphics thingy) and tesselation, the misspelled openGL function.

Cheers
Nate
