Oops, I completely forgot to print my poster for the Q&A session after the SIGGRAPH presentation... Let us try to fix this...
When dealing with noisy and/or partial inputs to describe a shape, the standard approach in geometry processing is to reconstruct a clean implicit surface first, and to do geometry on it. But why this one in particular? What about all the other surfaces that would have been coherent with the input?

Les sourciers affirment détecter de l'eau souterraine au moyen de différents dispositifs (baguettes, pendule...) Loin d'être cantonnés à des activités traditionnelles, on apprend en 2024 que certaines préfectures rendent leur passage obligatoire dans le cadre de grands travaux. Fil à dérouler ⬇️⬇️⬇️
Je viens de tomber sur ce texte de @kornetzke.bsky.social et je pense qu'il résume à la perfection ces dernières années. C'est un poème. Une ode.
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!
Baptiste GENEST@baptiste-genest.bsky.social · 10mo agoComputing 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!

RING meeting in Nancy, Cyprien Plateau--Holleville presented presented his awesome work on exact integration of the differential quantities involved in Partial Optimal Transport. And that's not all: It comes with a combined physsim - Optimal Transport - rendering on the GPU !
Voici l'infographie officielle de ce #ZEVENT2025 ! Merci à tous pour votre engagement dans ce weekend incroyable qu'on vient de vivre ensemble !
It was so good to be in Vancouver to present our work “Interactive Optimization of Scaffolded Procedural Patterns” at #Siggraph2025! If you couldn’t make it, have a look at our project page! 💻 marzia-riso.github.io/iospp.html Can’t wait for what’s next! 🎉
🚀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!
Axel Paris@axelparis.bsky.social · last yr.📜 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.
Differentiable rendering has transformed graphics and 3D vision, but what about other fields? Our SIGGRAPH 2025 introduces misuka, the first fully-differentiable path tracer for acoustics.
I will be presenting the paper "Lipschitz Pruning: Hierarchical Simplification of Primitive-Based SDFs" at SIGGRAPH 2025 during the Best of Eurographics session! Come to my talk on Wednesday morning wbrbr.org/publications...

C'est drôle parce que ce matin mon fils de 3 mois me disait: "Papa, pourquoi tous ces politicards minables et corrompus se sentent obligés d'inventer des dialogues d'enfants pour étayer leurs dérives fascisantes?" Et après il a rempli sa couche avec une parfaite imitation de François Bayrou.

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
![MOTIVATION
Graphical Processing Units (GPUs) are at the core of Computer Graphics research. These chips are critical for rendering images, processing geometric data, and training machine learning models. Yet, the production and disposal of GPUs emits CO2 and results in toxic e-waste [1].
METHOD
We surveyed 888 papers presented at SIGGRAPH (premier conference for computer graphics research), from 2018 to 2024, and systematically gathered GPU models cited in the text.
We then contextualize the hardware reported in papers with publicly available data of consumers’ hardware [2, 3].

Fun new paper at #SIGGRAPH2025: What if instead of two 6-sided dice, you could roll a single "funky-shaped" die that gives the same statistics (e.g, 7 is twice as likely as 4 or 10). Or make fair dice in any shape—e.g., dragons rather than cubes? That's exactly what we do! 1/n
🏅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!
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".
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.
After trying several broken repos/scripts, I made a Python script for rendering #ShaderToy shaders to antialiased video (or rather, image sequences): github.com/keenancrane/... (This one will surely be broken too someday, but for now it works nicely 😛)
This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social www.sciencedirect.com/science/arti...
