Real-time rendering of complex surfaces defined by atlas of discoids

Abstract

This paper expounds a new method of complex surfaces rendering permitting to visualize atlas of discoids in real-time. The atlas of discoids allow to define surfaces very easily without the topological constraints we could get with the classical methods such as polygons meshes ones. Our basic model is completed by many algorithms permitting either to reconstruct implicit surfaces or to calculate the global illumination using radiosity algorithm. But up to now, no fast viewing method has been proposed for this modeling algorithm. We present here a real time rendering algorithm which exploits the recent extensions of OpenGL library and the possibilities offered by GPU like the shaders programs to perform non standard fragments mixing operations.
