Glad to share with you our SIGGRPAH 2026 paper which received a Best Paper Award (Honorable Mention) 🎉
Kudos @baptiste-genest.bsky.social

BSP-OT is now available in POT main branch! github.com/PythonOT/POT
(👏 @baptiste-genest.bsky.social )
Looking forward to see you in Aachen and/or Los Angeles!

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.

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.

Super happy and proud of this!
Many thanks to @rflamary.bsky.social for his time and help 🙏
I'd strongly encourage anyone to contribute to the library, Rémy makes it easy!
Check out the example:

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?

We will give with Cyprien Plateau-Holleville a course on Fluid Simulation with Optimal Transport: New and Old at:
- Eurographics 2026 (May 4-8, Aachen)
- SIGGRAPH 2026 (July 19-23, LA)
Featuring:
- Gentle introduction to OT
- Create your own OT at home
- Fluid sim with OT
See you there !
