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?

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.
Une photo de Trump accompagnée d'un texte. Traduction trouvée sur Facebook:
"Regardez. 
La carcasse purulente de la pourriture américaine coincée dans un costume trop étroit : la vulgarité d’un escroc, la lâcheté d’un déserteur, la gloutonnerie d’un parasite, le racisme d’un membre du Ku Klux Klan, le sexisme d’un pervers de ruelle, l’ignorance d’un ivrogne accoudé au bar, et l’avidité d’un vautour de fonds spéculatifs, le tout peint en orange et exhibé comme un cochon primé à une foire agricole. 
Ni un président. 
Même pas un homme.
Juste la distillation maladive de tout ce que ce pays jure ne pas être, mais a toujours été : l’arrogance déguisée en exceptionnalisme, la stupidité déguisée en bon sens, la cruauté vendue comme de la force, l’avidité glorifiée comme de l’ambition, et la corruption adorée comme un évangile. 
C’est l’ombre de l’Amérique faite chair, une idole-citrouille pourrissante prouvant que lorsqu’une nation s’agenouille devant l’argent, le pouvoir et la rancune, elle ne perd pas seulement son âme, elle défèque cette obscénité boursouflée et l’appelle un chef."

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!

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!

🚀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!)

📜 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.

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

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".

Left: an input CSG tree and a much smaller pruned tree computed using our method.
Right: a rendered scene showing the number of active nodes per cell. Our method reduces the active nodes to less than 20 from the initial 6023 nodes of the input tree.

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 😛)
