GeoWarp: An automatically differentiable and GPU-accelerated implicit MPM framework for geomechanics based on NVIDIA Warp
Yidong Zhao, Xuan Li, Chenfanfu Jiang +1
The material point method (MPM), a hybrid Lagrangian-Eulerian particle method, is increasingly used to simulate large-deformation and history-dependent behavior of geomaterials. Wh…
Dress-1-to-3: Single Image to Simulation-Ready 3D Outfit with Diffusion Prior and Differentiable Physics
Xuan Li, Chang Yu, Wenxin Du +5
Recent advances in large models have significantly advanced image-to-3D reconstruction. However, the generated models are often fused into a single piece, limiting their applicabil…
PhysMotion: Physics-Grounded Dynamics From a Single Image
Xiyang Tan, Ying Jiang, Xuan Li +4
We introduce PhysMotion, a novel framework that leverages principled physics-based simulations to guide intermediate 3D representations generated from a single image and input cond…
Soft Hybrid Aerial Vehicle via Bistable Mechanism
Xuan Li, Jessica McWilliams, Minchen Li +2
Unmanned aerial vehicles have been demonstrated successfully in a variety of tasks, including surveying and sampling tasks over large areas. These vehicles can take many forms. Qua…
Lagrangian-Eulerian Multi-Density Topology Optimization with the Material Point Method
Yue Li, Xuan Li, Minchen Li +3
In this paper, a hybrid Lagrangian-Eulerian topology optimization (LETO) method is proposed to solve the elastic force equilibrium with the Material Point Method (MPM). LETO transf…
