1. A graphics processor that receives parameters defining a polygon from a host processor and rendering said polygon with texture in successive orthogonal scan lines, said texture stored in a set of texture maps, each texture map including one or more texel values identified by a texel coordinate and each texture map in said set varying by the number of texel values, comprising: a polygon engine for determining a starting x coordinate, a starting y coordinate, a width for each scan line, and a counter defining the number of scan lines; and a texture map engine for blending together texel values from more than one texture map based upon an area calculated by said texture map engine for a texel coordinate based on a cross product of vectors defined by texel coordinates in a texture map.
