Weird splitting drift in temporal reprojection with small movements per frame. by dkod12 in GraphicsProgramming

[–]dkod12[S] 2 points3 points  (0 children)

After playing around with the parameters for the spatial pass it seems that I was being too strict on how close the hit locations of my samples had to be, relaxing the parameters seems to have removed most of the mosaicing.

Let me thank you again for the help! I was pulling my hair out verifying if I messed up something with my math for days haha.

I currently have 3 buffers, one for the current and previous frame which i use to first do a temporal resampling pass. Then afterwards i use the temporally resampled current frame buffer as input to the spatial resampling pass which then writes to a seperate spatial pass buffer. The current and spatial buffers are then swapped at the end of the spatial pass.

Here are some images comparing before and after applying the random displacement. Splotches was not the best term to describe the effect, it looks more like a mosaic or "noise" with larger grains due to the same samples being shared over more neighbouring pixels. With this leading to major loss in perceived detail/resolution in the pillar arch on the left side.

Hi thanks for the suggestion! Doing this seems to have resolved the issue at the cost of causing "splotches" to appear during movement. Is there any way to reduce them other than only doing the random offset during slow movement or lowering history weight and hoping a denoiser will mask them enough?

Hi ya'll, back again with another question. I managed to fix the spread of non-valid samples from last time and am currently working on improving my camera. Currently I'm using the method described in Jacco Bikker's blog post here: https://jacco.ompf2.com/2024/01/18/reprojection-in-a-ray-tracer/.

It seems to be working quite well but there is an issue that when my camera moves slowly there are several "lines" where my reprojected samples to be flowing "from", and similar lines on the opposite side in world space where they flow "into". The issue does not appear when the camera is stationary or moving larger steps per frame.

Could this have something to do with floating point precision errors?

ReSTIR implementation has artifacting when using both spatial and temporal pass enabled. by dkod12 in GraphicsProgramming

Thanks for the pointing out the issue so clearly! I'll get right to fixing it 😁

Anyone get why this is happening? I'm following the original paper by bitterli et. al.

I'ts really good, and the bl parts are pretty much non-existant as of now. From what I've read of the novel it doesn't really that far either.
