One of the worst forms of brainrot AI has cultivated is pessimism about basic research, ie the idea that important work can only happen inside a frontier/neo lab and only with 10k+ GPUs, so the rest should not even bother. What a bleak way to think about science. And it's false.

This entire game was built using Claude + Thrixel, an agentic 3D creation platform.
Thrixel: Generated high-quality, thematically consistent, editable 3D assets.
Claude: Assembled in Unity + wrote game logic.
1 /goal prompt + Thrixel Skills + <5 follow-ups
Repo coming👇
Can we apply gradient descent to discrete changes? In our new #SIGGRAPHAsia paper, we show that gradient descent can work on shape grammars, as in CAD and procedural modeling, but only if the grammars are designed correctly!
We show that these properties matter through ablations over grammar variants and compare against existing random-walk approaches like RJMCMC. Grammars that satisfy more of our guidelines consistently converge faster and reach better optima.
Our takeaway: Don’t just throw an optimizer at arbitrary grammars, design the grammar for descent!

Jack was one of the first students in our group 3DL! He did a couple of awesome works with us during his undergrad. Check out his papers and make sure to follow his journey as he starts as a PhD student in @uwcse with @AdrianaSchulz7 ! zzhang-18.github.io/

One thing that makes siggraph unique is that it’s so much more than just technical papers. I’m excited that @UChicagoCS will be active across several different forums: technical papers, workshops, emerging technologies, frontiers talks, and even a social meetup! Come meet us 🤩
#SIGGRAPH2022 here we come! My lab is doing:
(1) #XR/#VR meetup (w/ @michinebeling ) (2) Yudai Tanaka's (@Hoku5ai) electrical head actuation demo, (3) #haptics talk w/ Nicholas Colonnese (@RealityLabs), (4) metaverse workshop w/@marknb00, @michinebeling & @tengshanyuan join us!

Thrilled to share "GANimator: Neural Motion Synthesis from a Single Sequence", in this upcoming #SIGGRAPH2022 🤩
GANimator can produce novel animations for unique creatures that don't have large motion datasets! For example, this hexapedal crab 🦀(1/4)
