Martin Newell, Jim Blinn, and I told the story of the #UtahTeapot at #SIGGRAPH2026, celebrating the 50th anniversary of its first appearance at SIGGRAPH in 1976, which quickly turned it into a symbol of Computer Graphics. Watch here: www.youtube.com/watch?v=k-23...

At SIGGRAPH 2026 I saw this absolute banger of a paper by James and James. Beautiful imagery, matched by beautiful technical work, by a father and son team, which won a best paper award. I've always loved marbleization patterns. dougjam.github.io/mixwell-2026/ www.linkedin.com/feed/update/...

TinyBVH has just been 𝘂𝗽𝗱𝗮𝘁𝗲𝗱 𝘁𝗼 𝟭.𝟴.𝟬. For CPU ray tracing, it is now the fastest option in most cases - Outperforming Intel Embree and Madmann91 for BVH build time and single-ray performance. On GPU, performance exceeds 4B rays per second - 4 rays per pixel at 4k/120Hz. github.com/jbikker/tiny...

There's a new paper out in JCGT by @jamportz.bsky.social et al. that proposes a super simple modification of existing microfacet models to implement a retroreflection model. What's interesting is that although insanely simple, the model fits measured data pretty well! jcgt.org/published/00...

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...

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
