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

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. momentsingraphics.de/SiggraphAsia...

This would be exactly 10 years ago! #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!

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." www.youtube.com/live/ucRukZM...

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.

A new #TwoMinutePapers video featuring our Particle Merging & Splitting paper from 2021. Károly really must have forgotten it. :) www.youtube.com/watch?v=4X5T... If you'd like to read the paper or watch my presentation video, here is the project page: graphics.cs.utah.edu/research/pro...

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

Join me in congratulating @ankachen.bsky.social for receiving the prestigious Doctoral Dissertation Award at #SCA2025: computeranimation.org/program.html... 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: www.cs.cmu.edu/~kmcrane/Pro... And find some supplemental information—including pseudocode—here: www.cs.cmu.edu/~kmcrane/Pro...

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. More info and source code on the project page: graphics.cs.utah.edu/research/pro...

Our #SIGGRAPH2025 paper "Augmented Vertex Block Descent" presents an extremely fast and stable physics solver with hard constraints for handling joints and collisions. The project page has a 2D demo with source code and more details: graphics.cs.utah.edu/research/pro...
