Source Code: CPU Voxel Ray Tracer. jbikker March 28, 2019 Leave a Comment on Source Code: CPU Voxel Ray Tracer Posted in Source Code. 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 …

View code Cuda Voxel Raytracing Milestones. README.md. Cuda Voxel Raytracing. This is a realtime voxel ray tracing prototype. I aim to make it as powerful as possible (concerning speed and quality). It should be able to render millions of voxels, maybe even of different sizes (but still layed out in an axis aligned grid). ...

Ray-traced voxel engine : VoxelGameDev - reddit
https://www.reddit.com/r/VoxelGameDev/comments/cmsu9a/raytraced_voxel_engine/
This ray traces an octree of 3D voxel textures (each 32^3), with one primary ray, and one shadow ray. ... Models are either made by myself in MagicaVoxel, licensed art, and some are SDF generated from code (the trees). ... the ray tracing is all in glsl (relying on some OpenGL 4.x features). Lobster comes with an OpenGL engine in C++ underneath
A Fast Voxel Traversal Algorithm for Ray Tracing
http://www.cse.yorku.ca/~amana/research/grid.pdf
To correctly traverse the grid, a traversal algorithm must visit voxels a, b, c, d, e, f, g and h in that order. fiThe equation of the ray isu+tfivfor t ‡0. The new traversal algorithm breaks down the ray into intervalsoft, each of which spans one voxel. We start at the ray origin and visit each of these voxels in intervalorder.

A C++ implementation of "A Fast Voxel Traversal Algorithm for Ray Tracing" (John Amanatides, Andrew Woo). Works with any ray direction. Modified for selection by frame or convex polygon on a grid. This is a header-only implementation. Requires a C++14 compiler. Usage example: { using namespace trace; std::vector<V2d> points = { { 102, 363 }, { 304, 503 }, { 515, 387 }, { 423, 147 }, …
