WebDec 27, 2024 · The basis of all raytracing algorithms is the ray/axis aligned bounding box and ray/triangle intersection tests and this is where most of the tree traversal time is spent on. Accelerating this part of the raytracing algorithm, supporting 4 ray/box intersections or 1 ray/tri intersections per clock, is expected to give large performance gains.

WebA BVH is conceptually simple. It’s a tree of bounding volumes, where a bounding volume is usually an axis aligned bounding box that encloses all the surfaces you’ve got underneath it in the tree. An example of a simple BVH class in C++ looks like this: class BVH : public Surface {public: // Constructors and such here BBox bbox; Surface* left; Use the RTX Denoiser SDK for high quality, fast denoising of ray traced effects.
