ABSTRACT:
An image of objects in a three dimensional space is generated for display on a two dimensional pixel array in which N renditions of the image are averaged, with each rendition having a sub-pixel offset from the previous rendition, to produce an anti-alias filtering effect. The N sub-pixel offsets are arranged to produce a basic array which ensures N times oversampling of a selected class or classes of image feature. For example, to give good antialias filtering of edges closely aligned with the x-y axes of the pixel array, the offsets are chosen to ensure bisection of the pixel area (A) at N points in each of x and y.
