Abstract
A scan conversion algorithm for rendering antialiased vectors in a multi-processor graphics system comprises the following steps: providing signals to the processors indicative of scan lines the respective processors are responsible for, determining a first set of storage pixels to be rendered by the processors, rendering such storage pixel of the first set simultaneously, each by a different processor, determining a second set of storage pixels to be rendered, and rendering each of the second set of storage pixels substantially simultaneously by a different one of the processors. The determinations of the first and second sets of storage pixels are made in accordance with the signals indicative of scan lines for which the respective processors are responsible.
