Charles Babbage intentionally designed the computer as an automation of mental labor. Today, computer graphics automates visual art production via privately governed generative models. How did we get here?

Yay, GravoTet received the best paper award at SMI! 🎉
When we presented GravoMG, a fast multigrid solver for surfaces, the first question we got was: can you make this work for tetrahedral meshes? Tomorrow, Marcel Padilla will present the answer at SMI in Istanbul. Sneak preview: yes, it's really fast.

I recently completed my PhD thesis, where I developed algorithms for making geometric inferences from imperfect data (i.e. incomplete and inaccurate observations/representations of shapes, like broken meshes or point clouds).

I think this is a great article that puts to words something I've been thinking for a while about LLMs/AI/etc; as tools they clearly can be useful and are here to stay, but the real concern should be the effect it's having on the talent pipeline. (1/5)

Simple idea to filter out (some) LLM-written papers with non-existent references: check the reference file agains DBLP and desk reject if a certain % of citations doesn't exist.
