  • Determining texture coordinates in computer graphics
    Patent number: 5900882
    Abstract: The texture coordinates (u,v) of a point Q' are determined by: (1) determining the modified texture coordinates (u',v')=(u/z,v/z) by linear interpolation, where z is a world coordinate; (2) determining 1/z by linear interpolation; and (3) dividing (u',v') by 1/z. The division is replaced with multiplying (u',v') by the inverse of 1/z. The inverse is obtained using a lookup table (LUT). The LUT stores inverses of a few values. Linear interpolation is applied to the LUT output to increase the inverse value accuracy.
