A formal framework approach for ray-scene intersection test improvement

Abstract

The ray-scene intersection test is the most costly process when a scene is rendered. This process may be improved using any strategy to be able to speed-up it. Generally, any strategy used is based on the building of a spatial indexing in the scene domain or in the rays domain. However, there is no theory to formalize these techniques. In this paper, a formal framework approach for this technique is proposed.
