Here's how I did it: https://bitbucket.org/teoryn/image-approximation https://bitbucket.org/teoryn/image-approximation For converting the polys to pixels I render it with OpenGL and then extract the resulting image. I use ppm for both input and output, they're just a plain text file, and any decent image editor can convert to or from them.
