The University of Utah wrote a profile about my work.
It covers an award-winning Olympics project I contributed to at The New York Times, my ACM SIGGRAPH leadership, and my research at the Scientific Computing and Imaging Institute.

In 2026, I reprise my role as High-Performance Graphics papers chair, joined by Markus Kettunen.
The papers deadline is 8 weeks from now. Submit your performance-oriented graphics research and present it in LA, just before SIGGRAPH (July 17-19 2026)!

We had the Grand Finals of the Teapot Rendering Competition this week. These are original scenes by students at the #UniversityofUtah, rendered using their own ray tracers written in C++, commemorating the famous #UtahTeapot. You can see them all here:

This is really, really bad!
Totally agreed! We will have the curves and patch data, but without trimming and chamfers, unfortunately.
It is intended for real time and it can work at real-time frame rates, but caustics are still rather expensive for most real-time applications in practice.
Our #SIGGRAPHAsia 2025 paper "Sample Space Partitioning and Spatiotemporal Resampling for Specular Manifold Sampling" improves #realtime #caustics rendering.

Super nice! The interior really helps with glass materials.

An old reel to reel magnetic tape. It has a label, in Jay Lepreau's handwriting, proclaiming it to be "UNIX Original from Bell Labs v4 (see manual for fmt)"
While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973
Apparently no other complete copies are known to exist: https://gunkies.org/wiki/UNIX_Fourth_Edition
We have arranged to deliver it to the Computer History Museum
#retrocomputing
A cloud rendered using jackknife transmittance estimation and the formula used to do so.
Ray marching is a common approach to GPU-accelerated volume rendering, but gives biased transmittance estimates. My new #SIGGRAPHAsia paper (+code) proposes an amazingly simple formula to eliminate this bias almost completely without using more samples.

#BackToTheFuture
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.
Project page: ankachan.github.io/Projects/Moc...
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.
Project page: graphics.cs.utah.edu/research/pro...
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.
Project page: graphics.cs.utah.edu/research/pro...
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
