I am boycotting #SIGGRAPHAsia 2026 because it will be in Malaysia, where there are serious safety concerns for the LGBTQ+ members of our community, thereby excluding them. I will not attend, submit my work to, or perform any reviews for SIGGRAPH Asia 2026.

Yet, I'm excited about #SIGGRAPHAsia 2025!

I'm happy to hear that my diversity plug was obvious enough.

We won the Audience Choice award last night at #SIGGRAPH Real-Time Live! showcasing the fastest general-purpose physics solver ever! We call it "Augmented Vertex Block Descent."

Methods like NeRF and Gaussian Splats model the world as radioactive fog, rendered using alpha blending. This produces great results.. but are volumes the only way to get there?🤔 Our new SIGGRAPH'25 paper directly reconstructs surfaces without heuristics or regularizers.

My general recommendation: don't ever miss a talk by Chris Wyman, regardless of the topic.

At #SIGGRAPH2021, @ankachen.bsky.social presented a method that can capture over 1000 unique points on the human body using only standard cameras and passive lights, without relying on temporal tracking or prior human body models.

At #SIGGRAPH2023, @ankachen.bsky.social presented a method for efficiently computing the exact shortest path to the boundary of a mesh from a given internal point in the presence of self-intersections.

The Vertex Block Descent (VBD) method @ankachen.bsky.social presented at #SIGGRAPH2024 is a new unconditionally-stable physics solver that has better parallelism and faster convergence than alternative methods.

The Offset Geometric Contact (OGC) method @ankachen.bsky.social will present at #SIGGRAPH2025 allows guaranteed penetration-free simulation of codimensional objects with minimal computational overhead.

Join me in congratulating @ankachen.bsky.social for receiving the prestigious Doctoral Dissertation Award at #SCA2025:

Anka's dissertation includes four major contributions to the field of computer animation (see the thread for details).

Is it even POSSIBLE?? 🟠

I talked to NASA scientists to find out. Listen here: link.podtrac.com/SciStuff_Mars

Code and other information coming soon; for now you can read the paper here:

And find some supplemental information—including pseudocode—here:

Meshes with 90° angles are super useful, providing asymptotically faster convergence for finite element simulation, and optimal shape approximation (when aligned with curvature).

Amazingly, no past quad meshing method could guarantee 90° angles under refinement—until now. #RSP

Making good on this promise—in the fastest turnaround time ever—my collaborator Etienne Corman has just posted MATLAB code for #RectangularSurfaceParameterization here:

github.com/etcorman/Rec...

(C++ version is still in the works…)

I am glad to attend #HPG2025 where I just presented our paper "Fused Collapsing for Wide BVH Construction", co-authored with Mathias Paulin. We propose a fast build algorithm for wide BVHs that directly computes a wide hierarchy without additional collapsing pass. Webpage: wbrbr.org/publications...

Jacob Haydel gave an excellent talk today at #HPG2025. You can watch the talk here:
www.youtube.com/live/SPWDLMc...

The video also includes all talks during day 1 of #HPG2025. Shout-out to the #HPG committee for live streaming all talks and making the recordings publicly available!

Our #HPG2025 paper "Arches: A Cycle Level Simulator for Exploring Massively Parallel Ray Tracing Architectures" will be presented by my student Jacob Haydel in a few hours. I will post the video when it is ready.

Our #SIGGRAPH2025 paper "Augmented Vertex Block Descent" presents an extremely fast and stable physics solver with hard constraints for handling joints and collisions.
