Improving BVH Ray Tracing Speed Using the AVX Instruction Set

The selective restructuring algorithm is performed at the be- ginning of each frame. We first perform BV refitting by up- dating the BVs in a bottom-up manner. However, these re-

We have tested our algorithm on the Patio scene, chang- ing its complexity from 21K to 705K triangles, and using three di ff erent specular reflectors: a smooth sphere, a 69K

We have developed a ray tracing approach that allows us to separately render the currently manipulated objects and the rest of the scene and to efficiently combine the partial

We in- vestigate the probability of visiting a node under this premise and derive a cost metric that improves ray tracing speed for many scenes at a slight increase in

The main contributions are (1) a top-down construction algorithm for creating tight-fitting SCB trees using a child orientation heuristic; (2) an efficient ray/SCB intersection

In this paper, Nvidia’s new OptiX ray tracing engine is used to show how the power of modern graphics cards, such as the Nvidia Quadro FX 5800, can be harnessed to ray trace

In this paper, we present our approach to optimizing coherent BVH ray packet tracing for the new AVX instruction set, which enables 8-wide SIMD operations on 32-bit
