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. www.linkedin.com/posts/flef_z...

🚀The code for Lipschitz Pruning is now online thanks to @wbrbr.bsky.social🚀 🔗 github.com/wbrbr/Lipsch... It's a simple Vulkan app useful for experiments. Also, the monument done by @elie-michel.bsky.social is released under a CC-BY license📄 (poke @mattkeeter.com I remember you asked!)

Vous avez sûrement déjà lu que la climatisation aggrave les canicules car l’air chaud rejeté à l’extérieur augmenterait la température des villes de 2 à 3°C. Vérifions ce que disent vraiment les études scientifiques à ce sujet 🧑‍🔬 (lisez jusqu’au bout, car vous allez être 🤯🤯 à la fin) #Thread ⬇️⬇️

Presenting this paper tomorrow morning at 9:30am, during the Lightning Fast Geometry session⚡ Come check it out if you can!

“In Finland, the number of homeless people has fallen sharply. Those affected receive a small apartment & counselling with no preconditions. 4 out of 5 people affected make their way back into a stable life. And all this is CHEAPER than accepting homelessness.” It costs a lot less to house people.

Il y a 10 ans, il y avait d’énormes manifestations pour défendre la liberté d’expression. Aujourd’hui, critiquer le premier ministre vous envoie en garde à vue et stage de citoyenneté - à vos frais. bsky.app/profile/ludi...

Par contre : plus de congés, la semaine de quatre jours et la taxation des riches - sans conditions sportives.

Ok, calmer, post-stream digested thoughts about GPT-5. I'll keep it short. 1. A lot of the presentation was vibes-based. "Is GPT-5 better at XYZ? This person said they feel it is. Ok, moving on..." I wonder how much this is because OpenAI think a lot of people use ChatGPT based on vibes already.

📜 New SIGGRAPH 2025 paper 🎉 ❔How to compute bounding volumes for procedural Signed Distance Fields (SDFs)? This is not so trivial! 💡We propose a simple method called Sphere Carving. It extracts (convex) bounding volumes around SDFs, requires very few evaluations, and is GPU compatible.

We're looking forward to presenting our talk at #SIGGRAPH2025 on Sunday Aug. 10 - 11AM, in West Building, Rooms 301-305!

I'm so happy to share that the stairs update is liiiiiive. This is by far our biggest update that we've been cooking since *checks calendar* omg, since March x_x Huge thanks to everyone who helped us test it while in beta <3 Now lemme walk you through some of the new shinies 🧵

Hardware virtual textures look like a marvelous tool for large terrains or volume compression. Alas, they are in a sad state in terms of performance and usability. And strangely, the (very bad) binding perfs varies a lot with the driver. → read here: hal.science/hal-05138369 @rcmz0.bsky.social

Triangles offer a natural strata to layout efficient non uniform random sampling on meshes. Our triangle rejection sampling reaches 10B samples/sec, which can feed primitive instancing, fiber distributions or emissivity sampling. Details in our HPG25 paper: research.adobe.com/publication/...

Another 🧵 on (almost) everything (interesting) about evaluating distances and closest points to quadratic Bezier curves

Holding SIGGRAPH Asia 2026 in Malaysia is a slap in the face to the rights of LGBTQ+ people. Especially now, when underrepresented people need as much support as we can possibly give them ! Angry like me ? Sign this open letter to let them know. 🏳️‍⚧️🏳️‍🌈 docs.google.com/document/d/1...

Ever wondered how badly we're all addicted to buying new GPUs in graphics labs? Come see our talk at #SIGGRAPH2025 to discuss how we can collectively move "Towards a sustainable use of GPUs in Graphics Research" with @elie-michel.bsky.social @axelparis.bsky.social Octave Crespel and Felix Hähnlein

The irony of writing an op-ed about how we need more numbers about AI's energy usage... and getting publicly attacked by corporate greenwashers about the fact that the numbers I use are inaccurate. I mean, yes, surely, but... the only way to prove that is by reporting them in the first place? 🤷

Si on accepte ça aujourd'hui de @info.gouv.fr ça ne s'arrêtera pas. Je refuse que l'État contribue à de la désinformation historique alors qu'il y a tant de fonds d'archives à valoriser avec le travail précieux d'historiens. Et on peut faire des reconstitutions plutôt que de s'en remettre à des LLM.

Thank you to everyone speaking up about this publicly. I am unsure why it had to come to this, but I sincerely hope that SIGGRAPH Asia will reverse course. alecjacobson.com/weblog/siggr...

🏅Honored to have been awarded at #Eurographics25 for our paper on #LipschitzPruning to speed-up SDF rendering! 👉 The paper's page: wbrbr.org/publications... Congrats to @wbrbr.bsky.social, M. Sanchez, @axelparis.bsky.social, T. Lambert, @tamyboubekeur.bsky.social, M. Paulin and T. Thonat!

This is based on "Lipschitz Pruning: Hierarchical Simplification of Primitive-Based SDFs", a new Eurographics paper from researchers at IRIT and Adobe Research (including @wbrbr.bsky.social): wbrbr.org/publications... It's very cool stuff, check it out!

Implicit surfaces are great, but if you are not Inigo Quilez, it's really hard to control how they look... That's why I'm really proud to annonce our Eurographics 2025 paper: "Implicit UVs: Real-time semi-global parameterization of implicit surfaces".

Want to know how to render SDFs made of thousands of primitives + CSG and smooth variants in *real time*? Come see @wbrbr.bsky.social talk next week at EG (and check the thread)! Great paper based on a simple idea

These pruned trees enable efficient evaluation of the SDF for rendering or discretization, resulting in >100x speedups for complex scenes compared to brute-force evaluation. Come to my talk next week for more details, or read the paper here: wbrbr.org/publications...

I am proud to announce our Eurographics 2025 paper "Lipschitz Pruning: Hierarchical Simplification of Primitive-Based SDFs"! With Mathieu Sanchez (joint first author), @axelparis.bluesky.social, @elie-michel.bsky.social, Thibaud Lambert, @tamyboubekeur.bsky.social, Mathias Paulin and Théo Thonat.

Nb : les étudiantes qui portent le voile sont déjà victimes de discriminations, très fréquentes, à l'université, sur le marché du travail ( recherche de stage, apprentissage...). Le rôle de l'Etat est d'agir contre ces discriminations, pas d'en faire la promotion active.

A key difference here is that while either can be incorrect, the structure of Wikipedia *creates context* and the structure of LLMs *destroys context* Wikipedia has linked sources and an edit history showing where information came from and who added it when An LLM just generates text

Crossing into the United States has become increasingly dangerous for digital privacy. Here are a few steps you can take to minimize the risk of Customs and Border Protection accessing your data.

Quelle époque opaque.

I see it. I have lived it. 83 years ago, the U.S. government turned upon a group of its own citizens and residents and sent them to internment camps without due process. I was there among them. American fascism is back. It is here. It is now.

1. LLM-generated code tries to run code from online software packages. Which is normal but 2. The packages don’t exist. Which would normally cause an error but 3. Nefarious people have made malware under the package names that LLMs make up most often. So 4. Now the LLM code points to malware.

Trevor Noah is cool and all, but there are so many things wrong with this video, which is essentially a great example of corporate AI greenwashing: 😐 - AI that is useful for sustainability is 𝗼𝗿𝗱𝗲𝗿𝘀 𝗼𝗳 𝗺𝗮𝗴𝗻𝗶𝘁𝘂𝗱𝗲 more efficient than general-purpose AI. www.youtube.com/watch?v=cgzT...

These cuts will have immediate impact, experts say. “We’re going to have patients die,” says Jade Pagkas-Bather, an infectious disease doctor at the University of Chicago who also specializes in HIV prevention. “Unnecessary, preventable death.” www.wired.com/story/cdc-gu...

There are days in life that shake you. I’m shattered 💔 to share that I just found out that the US Government terminated my 2024 NIH Director’s Early Independence Award (~$2 million), threatening my long-promised assistant professor job at Columbia University & academic career... 1/🧵

Just read that AI’s energy consumption in data centers is nothing to be worried about because most of the hyperscale datacenters running AI are "powered by renewable energy or low-carbon nuclear power." Let's debunk that, shall we?

Le monde reports that on March 9th a French scientist heading for a conference was denied entry to the US. His computer and cellphone were searched, and messages to friends were found where he expressed his opinion on the Trump admin and their politics wrt to science. www.lemonde.fr/internationa...

For a video explainer, I'm looking for scientists working in the US, or in collaboration with US scientists, or with US data's, whose work is impacted by the new Trump administration. 🙏If you are willing to be interviewed (video interview in a French newspaper) DM me !
