ABSTRACT:
An anisotropic texture filtering method using area coverage weight of sub-texel precision includes the steps of executing filtering by applying weights to texels; representing four sides of the footprint by four linear equations for computing area coverage weight; obtaining sub-texel masks from a table by addresses given by values of line equations; and calculating the final area coverage weight with four sub-texel masks obtained in the previous step.
