Texture Address Generator for Texture Mapping

摘要

The present invention relates to computer graphics, and more particularly, to a texture address generator that performs texture mapping. The apparatus comprises a texture interpolator for specifying texture addresses U and V of pixels on a edge having a minimum and a maximum value for the y direction in the plunge, edge interpolator); And an X interpolator for interpolating the output value of the edge interpolator in the x direction along the scan line as a start point and designating addresses of the texture addresses U and V corresponding to the pixels in the pligene,;The effect of the present invention makes it possible to set the texture address parameter to perform texture mapping inside the polygon in two ways, thereby reducing the amount of computation of data and enabling high-speed processing.
