PIPELINE.txt

The following is a summary of how the pipeline for this shader operates. Specifically, it's a list of the outputs for each program. Some of this information may be out of date or incorrect, but I hope it helps you understand this mess.

colortex7 contains atmosphere data
bluenoisetex contains blue noise

===LPV STUFF===
The floodfill lighting uses two custom images - lightvoxel and lightvoxelf
On even frames, lightvoxelf is the 'previous buffer' and lightvoxel is the 'current buffer'. On odd frames, this is swapped.

In shadow.vsh, light emitting blocks have their emission colour written to the **previous buffer** at their voxel position from the **previous frame**.
In shadowcomp.csh, for each voxel, samples are taken from **where that voxel was last frame** from the **previous buffer**, and then written to the **current buffer**.
