Image Denoising

We integrated OpenImageDenoise from Intel. It's very straight forward. Below you see the noisy render at 64 samples as well as the albedo image and normal image which we feed into our denoiser. The last image is the render after denoising.

Code:

src/postprocesses/denoising.cpp

Spoiler: Implementation of this feature in our final render

There do be less noise.
