Abstract

A color/texture interpolator (CTI) for use in rendering antialiased vectors in a computer graphics system comprises: an x-stepper circuit for receiving input data defining a vector to be rendered and generating respective pixel addresses of pixels composing the vector; a filter memory for storing predetermined filter values addressed according to the vector's minor axis subpixel addresses and slope; and a color interpolator for generating a color value for each pixel composing the vector.
