Ok, this reply comes a bit late, school kept me busy.
Now I'm playing around with the idea of making a 3d breakout game, so I guess some 3d maths would be quite usefull. The problem is that the examples don't work for me bcos my gfx card doesn't support vertex shading.
Questions:
1. x,y,z are the axes, but what is w?
2. What is a catmull rom interpolation, hermite spline interpolation, linear interpolation?
3. Anything else I should know?
Sorry to annoy you, but I guess this is a vital part to programming propper stuff (correct me if I'm wrong).
