Abstract

An apparatus and method for using non-power of two texture maps is described. Normalized texture map coordinates such as s and t are converted from a floating point format to a fixed point format and wrapping operations are performed to produce unnormalized texture map coordinates such as u and v corresponding to non-power of two texture maps.
