Abstract
A graphics processor comprises: a light source table holding light source data; a conversion unit for converting the light source data to be set in the light source table from a float type (single-precision floating point real number type) into an int type (integer type); an inner product calculation unit for calculating the inner products of normal directions, light source directions and sight line directions at the vertices based on the light source data; and a color calculation unit for performing light source computations based on the calculated inner products to determine the colors of the vertices.
