KD-Tree Acceleration Structures for a GPU Raytracer
https://graphics.stanford.edu/papers/gpu_kdtree/kdtree.pdf
scenes and determines that the kd-tree is the best general-purpose acceleration structure for CPU raytracers. It would seem natural, therefore, to try to use a kd-tree to accelerate GPU raytracing. As we will describe in section 2 though, the standard algorithm for kd-tree traversal relies on a per-ray dynamic stack. Ernst et al. [EVG04 ...

Download Interactive KD-Tree GPU Raytracing for free. We have implemented a raytracer in both CTM and DirectX (through brook). On modern architectures the raytracer gets between 10 and 20 million rays per second on 300,000 polygon scenes....

Over the past few years, the powerful computation rates and high memory bandwidth of GPUs have attracted efforts to run raytracing on GPUs. Our work extends Foley et al.'s GPU k-d tree research. We port their kd-restart algorithm from multi-pass, using CPU load balancing, to single pass, using current GPUs' branching and looping abilities. We ...

Realtime Raytracing: Kd-Trees on graphics cards
https://www.semanticscholar.org/paper/Realtime-Raytracing%3A-Kd-Trees-on-graphics-cards-Helmich/cbc77bbd40a5618fd35ae11ffc391725b761c589
Realtime Raytracing: Kd-Trees on graphics cards. This paper shows an overview to the todays generally accepted opinion data structures for ray tracing (grid, kd-tree and bvh) with attention to kd-trees. Furthermore the possibilities to schedule the kd-tree construction algorithms on graphical processing units (GPU) are discussed.
Is BVH faster than the octree/kd-tree for raytracing the …
https://computergraphics.stackexchange.com/questions/10098/is-bvh-faster-than-the-octree-kd-tree-for-raytracing-the-objects-on-a-gpu
Apparently most people use BVHs in their raytracers. The ray-AABB intersection code is very fast and and the BVHs also compresses empty space efficiently, working even with infinitely large objects, while octrees (a more uniform subtype of BVH) apparently have a problems with compressing large open worlds - no way you can insert into a finite grid that …
