dc.description.abstract-translatedA significant portion of rendering time in ray tracing consists of the traversal of an acceleration structure. While methods designed to reduce traversal cost often target the top of the tree, we instead propose a method that targets the lowest levels, by offsetting ray origins just before starting traversal. Our method moves ray origins out of nodes deep in the tree, avoiding the scattered memory access associated with these rarely visited nodes. We propose a precomputed set of hemispheres, placed on the surfaces, which is guaranteed not to contain any geometry, thus allowing rays starting inside a hemisphere to be moved to the hemispheres boundary. Our method is compatible with most acceleration structures and does not require access to the actual traversal implementation.en
