Generating partials for perspective corrected texture coordinates in a four pixel texture pipeline |
摘要 |
A method, program and apparatus for generating partial differential equations for perspective corrected texture coordinates in a computer graphics display are provided. The present invention comprises calculating texture coordinates for four adjacent pixels and then determining the differences between the coordinates. A perspective correction factor is then calculated, which is multiplied by each coordinate difference.
