GitHub - adobe/openpbr-bsdf: Adobe's reference implementation of the OpenPBR BSDF Adobe's reference implementation of the OpenPBR BSDF - adobe/openpbr-bsdf

Adobe just released an Apache-2.0 licensed reference implementation of the OpenPBR Surface standard, extracted from their in-house Eclair renderer.

Neat trick: the reference implementation cross-compiles for C++, GLSL, Cuda, Metal, and Slang!

I built a procedural medieval island map generator using Wave Function Collapse on hex grids. 4,100 cells, 900 possible states per cell, 60fps on mobile. Wrote up the whole process with lessons learned. Links below 👇 #threejs #webgpu

wrote a post about developing geometry libraries in this new reality where a robot can generate working code for damn near anything.

An image of a 3D roof generated using the procedural Straight Skeleton algorithm

I open sourced the Straight Skeleton algorithm we use in @dungeonalchemist.com to generate the roofs. It's a very complex algorithm that took a long time to get right, so I'm very happy to share it with the world!

If you need procedural roofs in Unity, check this out.

I gave an internal talk at UCSD last year regarding "novelty" in computer science research. In it I "debunked" some of the myth people seem to have about what is good research in computer science these days. People seemed to like it, so I thought I should share.

Je vous conseille l'intervention (à partir de 1h03) du directeur de l'école Méliès, ça parle de comment les écoles d'animation peuvent contrer la destruction de savoirs faire liés à IA générative en revenant aux bases de l'anatomie, du mouvement et de la composition d'image - sans logiciels.

Some procedural shapes I made in Unity and Desmos while writing my book "Shaders & Procedural Shapes." Should I add more?

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Modeling faceted geometry as a 4D point process on a multiscale implicit grid enables real-time glint rendering for standard NDFs, with IS, anisotropy, and colored particles. Memory-free, in a standalone fragment shader. Our SIGGRAPH Asia 2025 paper: research.adobe.com/publication/....

Super happy and honored to share that our paper "BSP-OT: Sparse transport plans between discrete measures in log-linear time" won a *Best paper award* at SIGGRAPH Asia 2025!

If you are here, come see my presentation about this work Wednesday afternoon!

Many thanks to the award committee!

It's roughly 4 years since I started to work on the 3D sparse fluid solver for what will ultimately become EmberGen 2.0.

A quick look at the current performance state of the solver.

Annulation d’un colloque sur la Palestine au Collège de France : la chaîne du scandale L’annulation, sous pression du ministre de l’enseignement supérieur et de la recherche, d’un colloque du Collège de France consacré à la Palestine, constitue un opprobre démocratique et scientifique.

La recherche basée sur la discussion méthodique appuyée sur les faits et le raisonnement, ne peut pas exercer sa mission d'intérêt général si elle est soumise à la validation politique a priori.

Les libertés publiques sont notre affaire à toutes et tous.

Pendant 20 ans, on m’a dit que pirater les œuvres des artistes c’était le mal absolu et que ça allait détruire la culture, et maintenant on me dit que oh bon, les IA génératives, qu’est-ce qu’on y peut, hein, les gens vont s’en servir de toutes façons.

Présentement dans un train où deux mecs discutent doctement du fait que dans 4 ans plein d'emplois vont disparaître à cause de l'IA et qu'ils utilisent chatGPT pour lire des histoires à leurs enfants 🤪

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

Loved this article, thank you for sharing. It's great to see all these numbers and backed-up arguments all in a single place. Not that I needed some more convincing, but I'll use it myself to convince other people :D

Working my way through @edzitron.com 's article about the AI bubble. It's fantastic. I do kinda know all this stuff peripherally, but to see it all laid out very clearly with hard numbers is incredibly useful. Thanks Ed!

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable…

In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!

OpenAI's new Sora video generator to require copyright holders to opt out, WSJ reports OpenAI is planning to release a new version of its Sora video generator that creates videos featuring copyrighted material, unless copyright holders opt out of having their work appear, the Wall Street Journal reported on Monday, citing people familiar with the matter.

Un graphique affichant avec une courbe bleue l'évolution, à chaque minute, du nombre de signatures affiché sur le site, sur une période de nuit. Une seconde courbe rouge est derrière, quasi identique, à un détail près : 4 pics de 50 signatures, qui correspondent aux moments où j'ai simulé des signatures. C'est ce qui aurait dû apparaître si le compteur n'était pas truqué.

Les 1,8 millions de signatures de la pétition de Philippe de Villiers contre l'immigration sont complètement bidons, et je peux le prouver.

Mais il y a plus intéressant, ce qu'il y a derrière, à savoir une opération de l'empire Bolloré. Un thread 🧵⤵️ https://t.co/hHF2dUqi8Z

Eh ben celle-là, en termes de tartufferie, elle vient de faire péter le plafond de la Sixtine.

i don’t think people on bluesky understand the severity of this situation.

i woke up to literally hundreds of texts from friends and family thinking about either moving back home to india or applying to other countries for jobs. this includes me.

En 1970, tous les banquiers d'Irlande ont fait grève. Ils pensaient que ça mettrait le pays à genoux. Raté. Après 6 mois, tout allait toujours bien, le PIB a même augmenté. Par contre quand les éboueurs de New York ont fait grève 10 jours, il a fallu déclarer l'urgence sanitaire.

Ce week-end, j'ai pas mal donné mes tripes :/

Les papiers qui en sont sortis n'étaient pas les mieux, mais j'ai essayé de coucher un article de fond construit, sur comment fonctionne la dynamique audience/influenceurs d'un événement comme le ZEvent.
