Antialiasing : Prefiltering

Antialiasing minimizes the effects of aliasing. One method, called prefiltering, treats a pixel on the object as an area (Catmull, 1978). It maps the pixel’s area into the texture map. The average color is computed from the pixels inside the area swept out in the texture map.
