Geometry-Centered 3D Latent World Models for Growing Surfaces
Xiaoyi Liu, Hao Tang
Many physical systems do not merely move or deform; they grow, adding material and changing the geometry that a world model must represent. Existing world models are typically opti…

Cabbage: A Differential Growth Framework for Open Surfaces
Xiaoyi Liu, Hao Tang
We propose Cabbage, a differential growth framework to model buckling behavior in 3D open surfaces found in nature-like the curling of flower petals. Cabbage creates high-quality t…

DiffFNO: Diffusion Fourier Neural Operator
Xiaoyi Liu, Hao Tang
We introduce DiffFNO, a novel diffusion framework for arbitrary-scale super-resolution strengthened by a Weighted Fourier Neural Operator (WFNO). Mode Rebalancing in WFNO effective…
