Geometry-Aware Anisotropic Boundary Correction for Aerodynamic Simulation
Xin Zhang, Yipeng Huang, Shu Jiang +2
Aerodynamic simulation is a key component of engineering shape design, where core quantities such as the surface pressure coefficient strongly depend on flow dynamics near solid bo…
VisionLaw: Inferring Interpretable Intrinsic Dynamics from Visual Observations via Bilevel Optimization
Jiajing Lin, Shu Jiang, Qingyuan Zeng +2
The intrinsic dynamics of an object governs its physical behavior in the real world, playing a critical role in enabling physically plausible interactive simulation with 3D assets.…
Phys4DGen: Physics-Compliant 4D Generation with Multi-Material Composition Perception
Jiajing Lin, Zhenzhong Wang, Dejun Xu +3
4D content generation aims to create dynamically evolving 3D content that responds to specific input objects such as images or 3D representations. Current approaches typically inco…
Fading the Digital Ink: A Universal Black-Box Attack Framework for 3DGS Watermarking Systems
Qingyuan Zeng, Shu Jiang, Jiajing Lin +3
With the rise of 3D Gaussian Splatting (3DGS), a variety of digital watermarking techniques, embedding either 1D bitstreams or 2D images, are used for copyright protection. However…
