Motion Blur Corner Cases

Abstract

This chapter describes efficient ways to handle some corner cases in motion-blurred acceleration structures for ray tracing. We discuss the handling of geometries sampled at different time intervals, how to efficiently ound the movement of geometries undergoing linear transformation and linear deformation at the same time, and a heuristic for bounding volume hierarchy (BVH) construction that helps the surface area heuristic adapt to the presence of incoherent motion.
