ABSTRACT:
A method and apparatus is disclosed for preprocessing fragments of two-dimensional graphic objects prior to display in a real-time rasterized format. The apparatus is formed as a pipeline having a translation and scaling section, a filter section, a pre-calculation section, and an interlace correction section. The preferred embodiment is specifically configured to process quadratic polynomial fragments (QPFs) of objects, and to calculate QPFs at high speed thereby permitting real-time rendering on a display. The preferred embodiment also forms part of a real-time object based graphics system.
