@HereForOneGhost @sensha_do @MintFantome oh does the version that's coming out on monday have anything new? or is it just trimming down the original vod? i'm debating whether to watch it now or later

While the fanbase formerly known as wisps continues to go nameless for the foreseeable future I have decided to make the bold decision to name myself and invite others to follow suit I'm Pomu 🧚🍂

been watching clips of the bocchi the rock live stage and man it looks like a lot of fun and the live performances are actually pretty good. it's probably an impossible dream but i hope i'll have the chance to watch smth like that in person one day

@cyanoacry I've been idly thinking about this ever since pomu put herself on that high altitude weather balloon. unfortunately getting to orbit and beyond is probably still beyond the reach of a fully fan (funded + made) effort 🥲

@yiningkarlli There's... a live action Moana remake? as in, the same Moana that came out less than ten years ago...?

So there was this really great Youtube video that came out over the weekend about why a lot of modern movies just don't feel "real" anymore and generally kind of look terrible. Anyhow in other news I just saw the trailer for the live action Moana remake. youtube.com/watch?v=tvwPKB…

@romblymo @naniwa_zuni but is ricotta even flavorful enough to be noticed in a white sauce? you're basically melting milk into more milk

@naniwa_zuni Just put Ricotta in you're Bechamel and then rub your big belly after eating it

@lisyarus Perhaps the mismatch is simply too big then? In my experiments, I found that ignoring even just one term (visibility, so V * Li * fr -> Li * fr) introduced a surprising amount of noise

@turtlespook The target function is costly to evaluate, so I'm approximating it with a gaussian, and the RIS weights come from this gaussian

Sampling the gaussian lobe using reservoir sampling and using it as the importance direction. Once again the amount of noise is pretty much the same as with uniformly random directions :/

@lisyarus I wasn't sure from your description whether you're using {hemisphere, Gaussian, SH, etc.} purely for sample generation, or to calculate the weights as well

@lisyarus I could be way off-base on this, but I think a key part of reservoir sampling is using a target function (weight) that matches the integrand? If any of the terms are neglected - visibility, Li, BRDF - you'll end up with some residual noise

standard bokeh vs swirly bokeh people pay a lot of money for special pieces of glass that do this to light. turns out its not that complicated to simulate in blender :)

@KostasAAA Very cool! is there some kind of "canonical reference" for the spatial hashing technique? I've seen the term used for GI solutions (like this), some ML stuff (instant-NGP), collision detection/nearest neighbor search... it's not clear to me if they're referring to the same thing

Did a quick and dirty implementation of a spatial hash structure to speedup RTAO, ray results are stored in cells indexed by pos/normal/cell size and after storing a few rays occlusion can be queried from the cell instead of raytracing it. 3x faster RTAO with no denoising.
