Claim One:
1. A method for interpolating first and second pixels using multi-channel texture mapping in a texture engine supported by limited-precision graphics hardware, comprising the steps of: (1) selecting a first channel of data of the first pixel and a second channel of data of the second pixel, each channel of data having a number of bits greater than a precision bit threshold of a texture channel of the texture engine; (2) separating the first channel of data into a first group of data segments in multiple texture channels, each data segment of the first group of data segments having a number of bits within the precision bit threshold of the texture channel of the texture engine; (3) separating the second channel of data into a second group of data segments in multiple texture channels each data segment of the second group of data segments having a number of bits within the precision bit threshold of the texture channel of the texture engine; and (4) interpolating the first and second groups of data segments in each texture channel to obtain an interpolated pixel value for each texture channel.
