Split out OptiX AI Denoiser into a separate example that can post-process EXR files. #435

Closed devshgraphicsprogramming closed 4 years ago

devshgraphicsprogramming commented 4 years ago

Take ~anywhere from 1 to 3~ a multichannel EXR file + 3x3 camera rotation&scale matrix as input:

all need to have the same format and resolution
first ~file~ channel is HDR COLOR, second is ALBEDO, last is NORMAL

NOTE: The normals need to be transformed (because most software outputs world-space normals) according to a 3x3 camera rotation matrix (9 floats)

Run the denoiser and output a single-layer HDR EXR file.

Make sure the denoiser does not fuck with high-quality high-sample converged reference renders (doesn't make a good thing worse by trying to help).

I attach input files.

Suspended for now (needs multichannel OpenEXR to work)

Actually a nice upgrade would be to take a .txt list of files as input as well

Here are the multichannel renders
