Do you happen to know what those techniques might be called? Kinda hard to search for these kinds of things without knowing the right terms.
- esperent 2y agoNo, sorry. I had the same problem - I've seen people discuss them but never implemented ray marching myself. I tried to search and couldn't find anything, as you say it's tricky to search for. If you have GPT4 or similar this is the kind of thing it's (sometimes) good at answering though.
- shiandow 2y agoNot sure how much this will help but simply picking the centre of each pixel is causing severe aliasing. Using a more random selection would resolve that (it would get rid of the moire), but wouldn't prevent much noise. Some structured blue noise might help a bit. Alternatively you could try to use thicker rays, not sure how doable that is but that way you might be able to filter out some of the high frequency details (for the low resolution renders at least).
