ABSTRACT:
A method and apparatus for computing a level-of detail (LOD) value for the of texels of a texture map to pixels of a graphics image adapted to receive signals representing texel coordinates for texels of a texture map and pixel coordinates for pixels of a graphics image to calculate a level-of-detail (LOD). The apparatus computes the LOD by calculating the square of the ratio between the number of texels applied to one pixel from the texel and pixel coordinates, approximating a base-two logarithm of the square of the ratio, and dividing the result of the approximation by two to compute the LOD.
