[Csgl-users] about concave polygon

[时 之 砂 <sky...@fo...>]

Hello,
 I'm using csgl to create a concave polygon,I found GLUtesselator could do this and find a good example which is writen in c++,but when I want to translate it to c#,I stucked by some diferences between csgl and opengl(c++ ver.),I find out how to register CALLBACK method in csgl,but haven't find how to create a gluTessVertex,because of the parameters are quite different to C++version.And I didn't get any information about the parameters in csgl document,could anybody help me about this,a complete example or just some informations.That is all what I want,thank you very much!
