Pretty straightforward, but I've seen examples that didn't have it: I draw a box with on eachside a texture, I rotate it and then it happens: the last drawn face is always shown ontop of faces that are closer to the camera. How to prevent this? Thanks.

Enable backface culling and maybe also the depth test.

You have to enable Z buffering ( depth test ), i think the command is gl_Enable(GL_DEPTH_TEST)

Ah thanks :), the BF culling did it (as I had depth_test already enabled ;)) thanks ;)
