Modeling faceted geometry as a 4D point process on a multiscale implicit grid enables real-time glint rendering for standard NDFs, with IS, anisotropy, and colored particles. Memory-free, in a standalone fragment shader. Our SIGGRAPH Asia 2025 paper: research.adobe.com/publication/....

Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable…
In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!

❔How to compute bounding volumes for procedural Signed Distance Fields (SDFs)? This is not so trivial!
💡We propose a simple method called Sphere Carving. It extracts (convex) bounding volumes around SDFs, requires very few evaluations, and is GPU compatible.

![MOTIVATION
Graphical Processing Units (GPUs) are at the core of Computer Graphics research. These chips are critical for rendering images, processing geometric data, and training machine learning models. Yet, the production and disposal of GPUs emits CO2 and results in toxic e-waste [1].
METHOD
We surveyed 888 papers presented at SIGGRAPH (premier conference for computer graphics research), from 2018 to 2024, and systematically gathered GPU models cited in the text.
We then contextualize the hardware reported in papers with publicly available data of consumers’ hardware [2, 3].

Fun new paper at #SIGGRAPH2025:
What if instead of two 6-sided dice, you could roll a single "funky-shaped" die that gives the same statistics (e.g, 7 is twice as likely as 4 or 10).
Or make fair dice in any shape—e.g., dragons rather than cubes?
That's exactly what we do! 1/n
