The Microsoft DirectX Transform architecture enables you to write procedural surfaces. These DXSurfaces are not stored as an array of samples, but instead as a set of instructions that specify how to render a surface of arbitrary size and resolution. Procedural surfaces take up a fraction of the memory used to store bitmap images, and they can produce realistic marble and wood textures. The resulting surfaces can be used as background images.
