Here we are, SIGGRAPH 2026! Don’t miss @baptiste-genest.bsky.social ´s tech paper talk “Uncertainty-aware geometry processing on Gaussian Process Implicit Surfaces” on Monday 11h45 (Room 403A) during the “Winding Numbers and Surface Representation” session

#SIGGRAPH2026 attendees: I made a better webpage for the Technical Papers schedule. You can search, filter on keywords, and scroll through linearly (rather than opening a zillion folds) + add to calendar: keenancrane.github.io/siggraph-pap... Can also download a flat JSON & CSV of talks & times.

Yep I'm been playing with the BSP-OT solver and it is quite fast. The following interpolation is done on 300k samples and only takes a few seconds (but can only find permutations). Generating the GIF/animation is slower than solving the problem.

Glad to share with you our SIGGRPAH 2026 paper which received a Best Paper Award (Honorable Mention) 🎉 Kudos @baptiste-genest.bsky.social ACM blog post: blog.siggraph.org/2026/05/beyo...

Beyond Deterministic Surfaces: Uncertainty-Aware Geometry Processing - ACM SIGGRAPH Blog

Explore uncertainty-aware geometry processing on Gaussian Process Implicit Surfaces (GPIS), a SIGGRAPH 2026 Technical Paper on computing with noisy, incomplete, and uncertain shapes.

Baptiste GENEST@baptiste-genest.bsky.social · 2mo ago

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?

SIGGRAPH goes to #FAccT2026! Congrats to my co-authors @posada.website, @avmenon.bsky.social and @bsky.alexaschor.com We analyzed every SIGGRAPH, ToG, and SIGGRAPH Asia paper from 1974-2024 to see how race is imagined in graphics research. The results were not good. arxiv.org/abs/2605.14835 1/

Another Firing Squad Cellular Automata plot (Mazoyer’s solution).

Old but cool stuff, the Firing Squad Sync problem: For a 1d cellular automaton with n cells, how to design the transition rules (with the smallest number of states) such that all cells are synchronized at the same « FIRE » state?

I am very lucky to work with @nbonneel.bsky.social Vincent Nivoliers and @dcoeurjo.bsky.social !

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 Graphics Replicability Stamp Initiative (GRSI, www.replicabilitystamp.org), a community-driven initiative to promote replicability in Graphics research, is seeking volunteers. More details in the 'Volunteering' section of the home page.

We are happy to announce the major release 2.0 of DGtal (dgtal.org) 🎉. This big update makes the library more modern, in both how it is built and the tools it uses. This release also includes new features in both the C++ library and its python binding. #geometry-processing #c++ #python (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

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".
