Sparse Voxel Octrees for Realtime Raytracing! | Bray-3D
https://bray3d.wordpress.com/2010/07/26/sparse-voxel-octrees-for-realtime-raytracing/
For me, I have one sparse octree (a resolution of 1024^3) that represents a high level node partition of my scene. I call this octree the “indirection octree”. At each node in the indirection octree, I have a pointer to a “brick”. A brick is a sparse octree of size 128^3 whose leaves represent a voxel in the 3D texture.

Code went in today to render out and save uncompressed frames at 3840x2160 (4K). This lossless 22.7GB video was uploaded to Youtube at 4K so as to retain as ...
Ray Tracing Complex Objects Using Octrees

that multiple nodes will be struck by a ray. Testing for hits is extremely complicated and uses some complex parametric algorithms [4]. The nal aspect of the Octree implementation is the ray-octree intersection that needs to be calculated in order to know which leaf nodes are pierced by a ray. This is done by taking the ray parametric function ...

I got my hands on a 3090 for the next week, what ray tracing games/demos should I try? My friend let me use his 3090 for a week while he is away on business. So, I have popped out my trusty 1080ti, and am now ready to go with the 3090.

IMPLEMENTING RAY TRACING WITH OCTREES AND …
https://www.cs.umd.edu/~hjs/pubs/SameCG89.pdf
Abstract--A ray tracing implementation is described that is based on an octree representation of a scene. Rays are traced through the scene by calculating the blocks through which they pass. This calculation is performed in a bottom-up manner through the use of neighbor finding. The octrees are assumed to be
