The talk I presented at #SIGGRAPH2026 is now available on YouTube, for anyone who couldn’t attend or would like to revisit it :) youtu.be/OFJYBUArVPc?...

1/6 Excited to share our #SIGGRAPH2026 paper, Dual Contouring of Signed Distance Data! We propose a new method for reconstructing sharp meshes from discrete samples of signed distance functions (SDFs) that does not require gradients. Project page: gatc.cs.columbia.edu/projects/dua...

good news: my GPU-based SSAO implementation is looking good bad news: I'm discovering all of the ways that my CPU-based implementation is wrong

Screenshot of an unblurred occlusion map from screen-space ambient occlusion.  The model is a colonnade with stairs on the right and a set of columns on the left, supporting a balcony.The same model, with an occlusion field that is noticeably streaky in the X axis.  Not great!

There more I think about it, the more I think "critical AI" work written by (or "in collaboration with" or whatever) LLMs is an incredible opportunity space for grift, bc you can count on it reaching the readership that is least likely to be able to spot machine writing. But what a moral vacuum.

boy I’m sure glad we solved AI alignment before deploying modes that could autonomously jailbreak themselves and hack cloud provider infrastructure stuff could have gotten really weird
