Abstract
In a computer display system, a method for mapping textures to three dimensional surfaces divided into a one or more polygons including the steps of determining pixels to be utilized in describing a polygon, selecting a texture map having a scale chosen to reproduce accurately a texture value for pixels for a polygon, determining a plurality of texture coordinates of a pixel at a plurality of positions surrounding a center of the pixel, determining texture values at each of the determined positions, and blending the texture values at the points to produce a texture value for the pixel.
