Voxel Direct Lighting on the GPU
From the blog "Josh's Dev Blog"
We left off on voxels when I realized the direct lighting needed to be performed on the GPU. So I had to go and implement a new clustered forward renderer before I could do anything else. Well, I did that and now I finally have voxel lighting calculation being performed with the same code that renders lighting. This gives us the data we need to perform cone step tracing for real-time dynamic global illumination.
The shadows you see here are calculated using the scene shadowmaps, not b
