From time to time I receive questions on the depth aware upsampling mentioned in the INSIDE-rendering presentation: https://loopit.dk/rendering_inside.pdf#page=39

noisy blur

The goal of this technique is to take the texture-output from a half-resolution pass, containing the results of sampling volumetric fog - and scale it up to full resolution. This presents two challenges:

  • Making sure samples from the low-resolution buffer, do not spill on top of foreground objects in the high-resolution buffer
  • Making sure the samples in the volumetric fog can be properly accumulated by TAA after upsampling

glsl hash testing

just gathering the comments from https://www.shadertoy.com/view/WttXWX in a place I can actually find, which also has more markdown :)

OK, results are in: as 32 bit RNGs, the 3-round Wellons function here is marked as weak in just 2 tests, with no failures. The 2-round Wellons function has 4 weaks and 1 failure, the murmurhash derivative only slightly worse with 5 weaks and 1 failure. Jenkins and Wang have many failures (Wang fails almost everything) so aren't really in the running.

Individual tests (just the negative results from the 50 or so tests):
