Read the original article Hit count: 242

How can you map say, a square or circle, to a triangle in OpenGL without distortion? I'm not seeing it.

EDIT:

Bonus question: What are some good OpenGL ES tutorials online? Videos and articles count. (I've seen the Stanford University stuff on iTunes U and think it's excellent, but I want more.)
