One way to improve game performance is through the use of pre-processing. Before the program even runs, it can do a lot of the work that will be necessary at run-time. If your scene has many static objects or polygons and a moving viewpoint, then Binary Space Partitions (BSP) are a great way to speed up the scene drawing.

The midpoint algorithm provides a method for high speed perspective texture mapping without approximation. It is faster than brute force division, though not hugely. To write a 3D game using this method would be possible with a high specification PC but would leave little time for other processing.

In this article, we are going to cover the most basic form of texture mapping which is referred to as "affine" texture mapping.
