I am in awe at how good Ghost Of Yōtei looks, but I have two very small pronunciation notes for my dear friends at SP:
0) 怨霊 is in no way pronounced アンリオ. Please don't
1) the game isn't called Ghost of 予定. That is a very different game where you find ways to not show up for plans with friends

Hey graphics friends, has anyone seen an algorithm to make a blue noise point sequence, that used a density map? (non uniform points)
I have some ideas to make some, but i am not finding any prior work and think there's a good chance it exists but im just not finding it.

I've been trying to wrap my head around "next event estimation" in #raytracing. What exactly is it and how does it differ from the multiple importance sampling technique, presented e.g. here? lisyarus.github.io/blog/posts/m...

is there a bit hack way to round 32-bit floats to the nearest power of two interval, given some power of two interval size?
for example,
snap interval: 1/64 (0.015625)
value: 4637/256 (18.11328125)
should yield: 1159/64 (18.109375)
I feel like there should be something better than round(v/i)*i

In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same.
The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.

The Gaussian is a nice bumpy shape, but sometimes we hope for a smooth (i.e. C∞) function like the Gaussian that is 𝒂𝒍𝒔𝒐 compactly supported.
One such class of functions is called "Bump functions"
