Slides are up for our talk at the Graphics Programming Conference (GPC), with @domlaz.bsky.social and myself. #GPC25 #DOOM graphicsprogrammingconference.com/archive/2025...

It's easy to forget when you don't live in the UK how absolutely useless the train system is. It's hard to credit really, given that we basically invented the the train. We seem to have forgotten that they're actually supposed to work and be useful rather than being some sort of shared national pain

I got the first post about direct lighting material occlusion up on my blog. On this one I go over the commonly used micro-occlusion approach and its limitations, and I start digging into micro-shadowing as an improvement. irradiance.ca/posts/micros...

My general recommendation: don't ever miss a talk by Chris Wyman, regardless of the topic.

If you missed our segment in @dayofthedevs.org today, here’s @jkooza.bsky.social and some of his pals talking about what awaits you in #AWAYSIS. www.youtube.com/watch?v=R4sN... #indiedev #gamedev

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

Check out the latest from one of Kyoto's greatest!

Oooh, new glints paper at SIGGRAPH Asia 2025: perso.telecom-paristech.fr/boubek/paper...

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

O wow, ReSTIR keeps giving. Awesome stuff.

#SIGGRAPH - Save the date - Advances in Real-Time Rendering in Games will be Tue, Aug 12 - a full day course in 2 parts (Part I - 9am-12:15pm, Part II - 2pm-5:15pm). Stay Tuned for the program and the speakers - the line up is very strong this year!

Introducing GLSL Captcha. Pass the test by guessing the correct output for the GLSL shader code: glsl-captcha.vercel.app

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.

The SIGGRAPH Physically Based Shading course is back this year: blog.selfshadow.com/publications...

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...

Importance Sampled FAST Noise Here's a 25 minute video about the latest and greatest in blue noise textures / precalculated per pixel random numbers www.youtube.com/watch?v=aFSk... Also repo: github.com/electronicar... And published paper: jcgt.org/published/00...

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

JCGT announcements are now on BlueSky: bsky.app/profile/jcgt...

This is all purest gold.

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" 1/6
