The other problem is that DirectX has functions that deal with mathematical issues like rotations. But if I know well, OpenGL does not use such things. So I have to learn Maths applied in game programming. By the way, do you know a good book for beginners on D3D 10?
Any 3D library is going to involve rotations and translations and other matrix math operations. Probably some splines too. Yes, there's a fair bit of math you need to understand.

I'm surprised that D3D would require you to do all that extra stuff just to draw a cube. In OpenGL you certainly *can* specify textures and shaders and whatnot, but you don't have to for basic drawing.....
