中文摘要

PhysiFormer是一种用于物理合理3D物体运动的扩散Transformer。与在视图相关像素空间中操作的视频世界模型不同，PhysiFormer将物体表示为世界坐标中的3D网格，从数据中学习物理，而非显式强制刚性和因果性。

原文摘要

We present PhysiFormer, a diffusion transformer for physically-plausible 3D object motion. Unlike video world models that operate in view-dependent pixel space, PhysiFormer represents objects as 3D meshes expressed in world coordinates. Given the initial vertex positions and velocities, as well as object material type, rigid or elastic, the model samples future vertex trajectories. While related neural physics approaches build on ad-hoc latent spaces or explicitly enforce rigidity and causality,...
