HighOmega v3.0

This is the first release of HighOmega v3.0 code named King Mackerel.

It showcases both voxel-based and RTX-based real-time hybrid path-tracing with spatio-temporal de-noising among other techniques. Voxel-based hybrid path-tracing with spatio-temporal de-noising was initially showcased at i3D 2018.

It also debuts HighOmega 3.0's very own variance reduction measure supplanting path-tracing with real-time 3D radiosity mapping. This is made possible via dynamic scene voxelization followed by partial distance transforms and sphere-marched updates to (potentially diffuse) radiosity storing voxels in a de-coupled-from-visibility manner.

Please note that distant geometry, the sky, transmittive surfaces and light shafts (in this demo) use traditional lighting methods instead of path tracing.
