Ray Tracing Voxels :: Teardown General Discussions

Like with voxels, you can update parts of a model at a lower rate than the actual frame rate, or only when actual changes happen. Those texture pixels will store just like a voxel would in a persistent manner therefore turbo charging ray tracing performance. But of course, also at a cost to memory just like voxels would.
Raytracing Voxels : VoxelGameDev - reddit
https://www.reddit.com/r/VoxelGameDev/comments/gej846/raytracing_voxels/
With my current understanding, the best way to render a large set of voxels is to raytrace a SVO/DAG, because it's faster to to check large empty spaces, but I can't seem to wrap my head around how shaders work.
Real-Time Ray Tracing Part:1 Sparse Voxel Reflections
https://zerolight.com/news/tech/real-time-ray-tracing-part1-sparse-voxel-reflections
Ray tracing is a technique used in computer graphics to realistically recreate how light interacts with objects and materials in the real world. The colour of each pixel is calculated by casting rays from the surface of that object into the rest of the scene …
Next-Gen 3D Rendering Technology: Voxel Ray Casting
https://www.tomshardware.com/reviews/voxel-ray-casting,2423.html
If John Carmack doesn’t seem all that excited about ray tracing, it’s not because he’s unusually conservative and wants to see triangle rasterization remain the unchallenged rendering technique. As...

Ray-traced voxel engine : VoxelGameDev - reddit
https://www.reddit.com/r/VoxelGameDev/comments/cmsu9a/raytraced_voxel_engine/
Ray-traced voxel engine Media This ray traces an octree of 3D voxel textures (each 32^3), with one primary ray, and one shadow ray. For fun I recently turned the voxels into "dice" which makes for a more organic look. Uses 8xTAA. Runs at >60fps in 1080p on my 1080Ti, likely can be optimized to run fast on older hw too (or just use lower res).
Voxel Ray Tracing - Graphics and GPU Programming
https://www.gamedev.net/forums/topic/670559-voxel-ray-tracing/
1) Voxelnauts uses CUDA to perform raytracing on the GPU, this is essentially required to get interactive frame rates 2) Ray tracing is by looping through each pixel on the screen casting a ray against an octree to find the voxel and resultant color of that pixel. 3) This is a very complicated way of rendering 3d graphics
Source Code: CPU Voxel Ray Tracer – Jacco’s Blog
https://jacco.ompf2.com/2019/03/28/source-code-cpu-voxel-ray-tracer/
This source package is based on a somewhat old experiment on CPU ray tracing. The 3D world consists of voxels: a grand total of 8192x512x8192 of them, each with a 24-bit color, for a grand total of 128GB of raw data. The data is subdivided in chunks of 128^3 voxels, which are then compressed to a compact octree. ...
Regular voxel grids and RTX accelerated ray tracing
https://computergraphics.stackexchange.com/questions/9025/regular-voxel-grids-and-rtx-accelerated-ray-tracing
From what I gathered, one of the components of the RTX system (or any ray tracer, really) is an acceleration structure that speeds up the process of testing for intersections. You give the card an octree or a BVH (or something similar) and it uses it to quickly find the closest hit (or any other hits, for that matter).
Next-Gen 3D Rendering Technology: Voxel Ray Casting
https://www.tomshardware.com/reviews/voxel-ray-casting,2423-3.html
Before going into detail about the algorithm being discussed, we need to define certain terms, such as voxels, octrees, and ray casting. Not everybody has a Carmack to English dictionary handy....
