Abstract

In interactive 3-D graphics, the amount of geometric primitives passed to the display algorithm frequently exceeds rendering capacity. Visibility computation is used to reduce the amount of geometry that must be passed to the rendering engine. In this paper we propose an algorithm that exploits coherence to accelerate visibility computation in 2 1/2D and can be used for both, on-the-fly computation of potentially visible sets, and for accelerated generation of spans for a simple 2 1/2D rendering engine.
