Stiffness Fields on Skeleton--Surface Lines: Structured Physical Inference for AI-Driven Dynamics of Gaussian-Splat Entities
Physics-integrated Gaussian Splatting either prescribes material parameters by hand or estimates them point-wise from appearance, leaving unstructured numbers that inherit appearance confounding. We show that stiffness can instead be carried by structure: a two-dimensional field $F(s,t)$ on skeleton--surface lines, wit...
