Triangles offer a natural strata to layout efficient non uniform random sampling on meshes. Our triangle rejection sampling reaches 10B samples/sec, which can feed primitive instancing, fiber distributions or emissivity sampling. Details in our HPG25 paper: research.adobe.com/publication/...

The surface mesh of a landscape (top left) is enriched with tens of millions of grass blades, designed in path traced in real time using a procedural density map (bottom left).

I am proud to announce our Eurographics 2025 paper "Lipschitz Pruning: Hierarchical Simplification of Primitive-Based SDFs"! With Mathieu Sanchez (joint first author), @axelparis.bluesky.social, @elie-michel.bsky.social, Thibaud Lambert, @tamyboubekeur.bsky.social, Mathias Paulin and Théo Thonat.

Right: a rendered scene showing the number of active nodes per cell. Our method reduces the active nodes to less than 20 from the initial 6023 nodes of the input tree.

ControlMat casts the "image-to-material" problem as a controlled generative task, guiding in-distribution channels diffusion with the input and introducing new diffusion components such as "Noise Rolling" for tileability. More in our ToG paper (presented Friday at SIG Asia): tinyurl.com/controlmat.
