In this paper, we propose an hybrid CPU-GPU ray-tracing implementation based on an optimal Kd-Tree as accel-eration structure. The construction and traversal of this KD-tree takes benefits from both the CPU and the GPU to achieve high-performance ray-tracing on mainstream hardware. Our approach, flexible enough to use only
Hybrid CPU/GPU KD-Tree Construction for Versatile Ray Tracing
https://diglib.eg.org/handle/10.2312/conf.EG2012.short.013-016
The construction and traversal of this KD-tree takes benefit from both the CPU and the GPU to achieve high-performance ray-tracing on mainstream hardware. Our approach, flexible enough to use only a single computing unit (CPU or GPU), is able to efficiently distribute workload between CPUs and GPUs for fast KD-tree construction and traversal.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We propose an hybrid CPU-GPU ray-tracing implementation based on an optimal Kd-Tree as acceleration structure. The construction and traversal of this KD-tree takes benefit from both the CPU and the GPU to achieve high-performance ray-tracing on mainstream hardware.
KD-Tree Acceleration Structures for a GPU Raytracer

grid acceleration structures. In contrast, the kd-tree has gained widespread use in CPU-based raytracers and is regarded as the best general-purpose acceleration structure. We demonstrate two kd-tree traversal algorithms suit-able for GPU implementation and integrate them into a streaming raytracer. We show that for scenes with many
SAH Based KD Tree Construction on Hybrid Architecture
https://ieeexplore.ieee.org/document/5959680/
KD tree is one of the most widely used acceleration structure for ray tracing. High quality KD tree has the ability to avoid many unnecessary ray traversal and ray-triangle intersection calculations. The best method to construct a high quality KD tree is by using Surface Area Heuristic (SAH). However, the SAH computation is expensive. In this paper, we present a …

https://graphics.stanford.edu/papers/i3dkdtree/gpu-kd-i3d.pdf
A typical k-d tree traversal algorithm takes a k-d tree, a binary tree of axis aligned splitting planes that partition space, and a ray as input and returns the rst triangle the ray intersects. Traversal walks the ray through the tree so that it visits leaf nodes, …
Real-Time KD-Tree Construction on Graphics Hardware

GPU Ray Tracing: We implemented a GPU ray tracer for arbi-trary dynamic scenes using our real-time kd-tree construction (Sec-tion 4). The ray tracer achieves interactive rates with shadow and multi-bounce reflection/refraction. Ours is the first GPU ray tracer for general dynamic scenes that outperforms state-of-the-art multi-

It should be noted that the accumulation of the storage arrays is a sufficient and optimized representation of the k-d tree. However, the k-d tree with nodes and references is built to be compatible with the original CPU version. Completion. This completes the building of the Kd Tree. The code shared here also includes a GPU based tree verifier that is also a breadth-first …
