High speed high quality antialiased vector generation

Abstract

A vector generation method is described in which a high quality image rendering scheme is coupled with a high speed scan-conversion algorithm.The rendering scheme consists of two parts. First a prefiltering method is used to antialias the vectors. Second a compositing technique is used to compose the vectors into the frame-buffer.The scan-conversion algorithm presented allows a single vector to be scan-converted by a either by a single processor or a set of processors running in parallel. When using parallel processors, antialiased vectors may be scan-converted and written to a frame store at the same high speed as aliased vectors. The VLSI technology used to implement this algorithm is capable of drawing over two million high quality antialiased vectors per second.
