AnimaMimic: Imitating 3D Animation from Video Priors
Tianyi Xie, Yunuo Chen, Yaowei Guo +5
Creating realistic 3D animation remains a time-consuming and expertise-dependent process, requiring manual rigging, keyframing, and fine-tuning of complex motions. Meanwhile, video…
SPARK: Sim-ready Part-level Articulated Reconstruction with VLM Knowledge
Yumeng He, Ying Jiang, Jiayin Lu +2
Articulated 3D objects are critical for embodied AI, robotics, and interactive scene understanding, yet creating simulation-ready assets remains labor-intensive and requires expert…
VoroLight: Learning Voronoi Surface Meshes via Sphere Intersection
Jiayin Lu, Ying Jiang, Yumeng He +2
Voronoi diagrams naturally produce convex, watertight, and topologically consistent cells, making them an appealing representation for 3D shape reconstruction. However, standard di…
Birth of a Painting: Differentiable Brushstroke Reconstruction
Ying Jiang, Jiayin Lu, Yunuo Chen +4
Painting embodies a unique form of visual storytelling, where the creation process is as significant as the final artwork. Although recent advances in generative models have enable…
Right-Side-Out: Learning Zero-Shot Sim-to-Real Garment Reversal
Chang Yu, Siyu Ma, Wenxin Du +9
Turning garments right-side out is a challenging manipulation task: it is highly dynamic, entails rapid contact changes, and is subject to severe visual occlusion. We introduce Rig…
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…
JGS2: Near Second-order Converging Jacobi/Gauss-Seidel for GPU Elastodynamics
Lei Lan, Zixuan Lu, Chun Yuan +5
In parallel simulation, convergence and parallelism are often seen as inherently conflicting objectives. Improved parallelism typically entails lighter local computation and weaker…
Penetration-free Solid-Fluid Interaction on Shells and Rods
