Partition de volumes d'ombres : une alternative pour le rendu d’ombres en temps réel

Abstract : This thesis focuses on exact per pixel hard shadow computation. We propose a new method for rendering hard shadows using a partition of shadow volumes : first, a ternary tree based on the shadow planes of the shadow volumes, and then, it is traversed to determine the shading of each pixel in the image. An interesting property of this structure is the predictability of its memory footprint ; Unlike other geometric shadow methods, our approach supports complex scenes up to a million triangles thanks to the logarithmic behavior of the structure traversal with respect to the geometric complexity.
