USDCraft: Geometrically Grounded Programmatic Modeling of Articulated 3D Assets for Simulation
USDCraft enables generating and manipulating complex 3D assets by treating reconstruction as programmatic modeling based on partial geometric evidence. It uses a pre-trained LLM to write executable programs for simulation-ready assets, grounded by analyzing source geometry into metric text representations. This allows for asset creation without task-specific training while ensuring geometric accuracy.
