How can I fill a ring-shaped 2D polygon with OpenGL? Is it possible? All I am getting is a filled circle-shaped polygon instead of a ring Breaking up is hard to do

And if you don''t want to mess with GLU''s tesselation, you can do it yourself by just generating your polygon and draw it with GL_TRIANGLE_FAN.
