Abstract
Improved computer graphics system texture interpolation is provided using texture rules and planar texture interpolation. A texture rule is defined which characterizes texture variation within an area defined by a set of texels. The texture rule is used to select a texture plane which approximates the texture mapped to a pixel. This texture plane is used to generate a texture value for the pixel. In one embodiment, the texture rule identifies a triangle pair defined by four texels. One of these triangles is selected based on the position of the pixel relative to the texels. The pixel is then mapped to the plane defined by the selected triangle and the texture value for the pixel is calculated by interpolating the texture value at the location in the plane to which the pixel was mapped.
