Voxel Ray Tracing and Physically-Based Rendering - Ultra Engine
https://www.ultraengine.com/community/blogs/entry/2638-voxel-ray-tracing-and-physically-based-rendering/
Voxel ray tracing overcomes these problems. The 3D voxel structure provides better reflections with depth and volume, and it's dynamically constructed from the scene geometry around the camera, so there is no need to manually create anything.
Voxel ray tracing and motion - Development Blog - Ultra Engine
https://www.ultraengine.com/community/blogs/entry/2585-voxel-ray-tracing-and-motion/
So far the new Voxel ray tracing system I am working out is producing amazing results. I expect the end result will look like Minecraft RTX, but without the enormous performance penalty of RTX ray tracing. I spent the last several days getting the voxel update speed fast enough to handle dynamic ...
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

Voxel Cone Tracing is similar to Ray Marching in the sense that we trace a few rays, and march across them until we hit obstacles. But instead of sending hundreds of rays, we only trace 4 to 6 ‘rays’ (called cones) and use 3D mipmapping to detect obstacles further away
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).

duced. Going from one voxel to its neighbour requires only two floating point compar-isons and one floating point addition. Also, multiple ray intersections with objects that are in more than one voxel are eliminated. Introduction In recent years, ray tracing has become the algorithm of choice for generating high fidelity images.
How to get parallel GPU pixel rendering? For voxel ray …
https://stackoverflow.com/questions/66913186/how-to-get-parallel-gpu-pixel-rendering-for-voxel-ray-tracing
For voxel ray tracing. Ask Question Asked 1 year ago. Modified 12 months ago. Viewed 609 times 0 1. I made a voxel raycaster in Unity using a compute shader and a texture. But at 1080p, it is limited to a view distance of only 100 at 30 fps. With no light bounces yet or anything, I am quite disappointed with this performance.
