As graphics researchers or geometry teachers, we speak about 3D using screenshots, and that's just sad... What if you could make SLides on top of PolyscOPE? You can using SLOPE! Slope allows you to synchronize a 3D viewer, animated meshes, shaders, live demos, equations (& more) with your slides!

Stop doing random scribbles. Let’s go for replicable (up to rigid motion) doodles!

The tools use crossref and arXiv API to resolve DOI

I’ve put together a small set of command-line tools for dealing with DOI mess in BibTeX files and PDFs: - Check DOI/title/author consistency - Add missing DOIs (only for high-confidence matches) - Clean up DOI URLs - Check DOI references directly in PDFs github.com/dcoeurjo/bibtex-doi-checker

I know nothing about GPU programming, so I thought that BSP-OT on the GPU would not work because we are recursive then sequential... I asked Claude to give it a try in CUDA: x10 speed-up 😳 0.4s for 350k points in 3D, with the same quality as the CPU 😱 Here is the code: github.com/baptiste-gen...

Have you dug deep into an evolving area of visual computing? Consider submitting to the 2027 EG STARs track! STARs are survey reports providing insight into the current state of the art and future directions. They're impactful and highly-cited! eg2027.isti.cnr.it/call-for-sta...

#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.

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: pythonot.github.io/master/auto_... !

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/

As a young computer science student, I remember being amazed by this problem: a simple, purely theoretical setting, an extremely elegant algorithm, and fantastic illustrations. A starting point for a very long journey in research…

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?

Personally, overpic is my ultimate latex cheat code. I even ended up having a 0px png to get a global coordinate system in the all page… 😈 (+1 for tikz btw)

This is a fantastic program for people of underrepresented genders in the graphics (and hci/graphics) research space. Please share with your network and gently bully your colleagues and advisees into applying. Deadline March 27, application package is fairly light!
