摘要: Texture-map computations can be made tractable through use of precalculated tables which allow computational costs independent the texture density. The first example this technique, “mip” map, uses a set containing successively lower-resolution representations filtered down from discrete function. An alternative method using single table values representing integral over function rather than itself may yield superior results at similar cost. necessary algorithms to support new technique are explained. Finally, cost and performance is compared previous techniques.
