Method of bilinear texture filtering

摘要

A method of bilinear texture filtering comprising the steps of reading information of a pixel; calculating texture coordinate for the pixel according to the information of the pixel, the texture coordinate having integral portion and fractional portion; determining a pair of texels according to the texture coordinate; reading values of the pair of texel from texture; and computing the color of the pixel according to the values of the pair of texels by a weighted average of the fractional portion of the texture coordinate.
