Abstract:
1. A method for rendering graphical data, the method comprising using one or more processors of an apparatus to execute: rendering, in two dimensions, an aliased version of an element of a three-dimensional graphical object in a two-dimensional field comprising a plurality of pixels; sampling, in a single sampling operation, an edge portion of the two-dimensional aliased version of the element in the two-dimensional field; calculating a curve, using the one or more processors, based on the sampled edge portion that approximates but does not overlap the sampled edge portion and intersects a first subset of pixels; determining the respective proportional areas of each pixel of the first subset of pixels that is located between the curve and the sampled edge portion of the aliased version of the element; and rendering an anti-aliased version of the sampled edge portion based at least in part on the magnitudes of the respective proportional areas.
