PWM-ArtGen: Part World Model for Articulated Object Generation

arXiv 2026 35.5 method

TLDR

A part world model for articulated 3D object generation from a single image, learning joint visual dynamics and kinematic parameters.

Reasoning

The paper introduces a novel approach combining action and image diffusion to predict kinematic structure, addressing limitations of existing methods. Strengths include a curated dataset and strong zero-shot generalization; weaknesses include reliance on photorealistic synthetic data and lack of real-world validation.
