Merging voxel and ray tracing data provides great flexibility. For example, for diffuse rays, true mesh tracing is needed only near the beginning of the ray but for the rest of the ray we can use more efficient cone tracing without any visual artifacts. A similar optimization works with specular rays.

Voxel Cone Tracing could be seen as an approximated version of ray marching. The scene is voxelized and three voxels are generated, containing albedo, normals and emissive properties. In other words, we build a Minecraft-looking representation of the world: Albedo Normals We run a compute shader (‘VCT/Voxelizer’) to voxelize the scene.
Voxel-cone ray tracing (SVOGI) - Unity does what UE4 and …

Elemental demo was showcased more than a year ago and had SVOGI on the PC build, that is correct. More recent UE4 demo called Infiltrator is not using any kind of real-time GI, instead showing static baked lighting by Lightmass (same lightmapping system as was used in UE3). They have ditched it because it's not possible to get the effect to run ...

Voxel-based Volumetric Fog uses volume textures as a view-frustum-shaped voxel buffer to store the incoming light and properties of participating media. Light and FogVolume entities inject their data to the volume textures. After the textures contain all the data to visualize the fog, ray-marching is done through the volume textures.

This GI solution is based on voxel ray€tracing and provides following effects: Dynamic indirect light bounce from static and most of dynamic objects. Large scale AO and indirect shadows€from static geometry (vegetation, brushes and terrain). Works without pre-baking and does not require manual setup of many€bounce lights or light volumes.

The shadows are also cone traced, which I still need to fix up the artifacts (I think it may be to do with using surface voxelization instead of solid - to avoid self-shadowing artifacts I had to skip the base mip in the cone trace). No octrees are used yet, the entire scene sits inside a single 64x64x64 3d texture.

The cone tracing technique works best with a regular voxel grid because we perform ray-marching against the data like with screen space reflections for example. A regular voxel grid consumes more memory, but it is faster to create (voxelize), and more cache efficient to traverse (ray-march). So let’s break down this technique into pieces.
