This is very impressive, I love it when code has minimal (or no) dependencies, you really see what's going on under the hood. Could have used some more comments

This is very impressive, I love it when code has minimal (or no) dependencies, you really see what's going on under the hood. Could have used some more comments in the code itself though (there are basically none but the code is clean). I first thought the code would render into a window using OpenGL. But this is a plain software renderer with no hardware acceleration/OpenGL at all and it simply stores the rendered image into a picture file. There is no window or stuff like that. EDIT: The lessons in the wiki explain things so well that comments in the code really aren't necessary at all.
