Abstract
A method and system for implementing programmable texture lookups from texture coordinate sets. The method includes the step of generating a plurality of texture coordinates using a shader module. The shader module executes floating point calculations on received pixel data to generate the texture coordinates. A plurality of texture values are fetched using the texture coordinates. The fetching is performed by a texture unit coupled to receive the texture coordinates from the shader module. The fetching of the texture values is programmable with respect to the texture coordinates such that the number of texture coordinates are decoupled from the number of textures.
