Crow Computer Sciences Laboratory Xerox Palo Alto Research Center Abstract images resulted, the technique would be too cumbersome for Texture -map computations can be made tractable through use of anything very complex. precalculated Tables which allow computational costs independent of the Texture density. The first example of this technique, the "mip" map, uses a When Texture is mapped onto a surface it must be stretched set of Tables containing successivelylower-resolutionrepresentati ons filtered here and compressed there in order to fit the shape of the down from the discrete Texture function.
