Adaptive Volumetric Mechanical Property Fields Invariant to Resolution

ICML 2026poster

Accurate mechanical properties (or materials) Young's modulus ($E$), Poisson's ratio ($\nu$) and density ($\rho$) are essential for reliable physics simulation of digital worlds, but most 3D assets lack this information. We propose AdaVoMP, a method for predicting accurate dense spatially-varying $(…

FreeForm: Reduced-Order Deformable Simulation from Particle-Based Skinning Eigenmodes

CVPR 2026

We present a novel formulation for mesh-free, reduced-order simulation of deformable hyperelastic objects. Existing work in reduced-order elastodynamic simulation represents the input geometry by either meshes, which can be difficult to obtain due to challenges in scanning and triangulating complex

VoMP: Predicting Volumetric Mechanical Property Fields

ICLR 2026poster

Physical simulation relies on spatially-varying mechanical properties, typically laboriously hand-crafted. We present the first feed-forward model to predict fine-grained mechanical properties, Young’s modulus($E$), Poisson’s ratio($\nu$), and density($\rho$), throughout *the volume* of 3D objects.…

Articulated Kinematics Distillation from Video Diffusion Models

CVPR 2025poster

We present Articulated Kinematics Distillation (AKD), a framework for generating high-fidelity character animations by merging the strengths of skeleton-based animation and modern generative models. AKD uses a skeleton-based representation for rigged 3D assets, drastically reducing the Degrees of Fr…

CoT-VLA: Visual Chain-of-Thought Reasoning for Vision-Language-Action Models

CVPR 2025poster

Vision-language-action models (VLAs) have shown potential in leveraging pretrained vision-language models and diverse robot demonstrations for learning generalizable sensorimotor control. While this paradigm effectively utilizes large-scale data from both robotic and non-robotic sources, current VLA…

PartField: Learning 3D Feature Fields for Part Segmentation and Beyond

ICCV 2025poster

We propose PartField, a feedforward approach for learning part-based 3D features, which captures the general concept of parts and their hierarchy without relying on predefined templates or text-based names, and can be applied to open-world 3D shapes across various modalities. PartField requires only…

Revitalizing Optimization for 3D Human Pose and Shape Estimation: A Sparse Constrained Formulation

ICCV 2021poster

We propose a novel sparse constrained formulation and from it derive a real-time optimization method for 3D human pose and shape estimation. Our optimization method, SCOPE (Sparse Constrained Optimization for 3D human Pose and shapE estimation), is orders of magnitude faster (avg. 4 ms convergence)…

You2Me: Inferring Body Pose in Egocentric Video via First and Second Person Interactions

CVPR 2020oral

The body pose of a person wearing a camera is of great interest for applications in augmented reality, healthcare, and robotics, yet much of the person's body is out of view for a typical wearable camera. We propose a learning-based approach to estimate the camera wearer's 3D body pose from egocentr…

Single-Network Whole-Body Pose Estimation

ICCV 2019poster

We present the first single-network approach for 2D whole-body pose estimation, which entails simultaneous localization of body, face, hands, and feet keypoints. Due to the bottom-up formulation, our method maintains constant real-time performance regardless of the number of people in the image. The…
