PhysX-Omni generates 3D objects that are ready for physics simulation, handling rigid objects, soft bodies, and articulated structures in one framework. The system uses a new geometry representation optimized for vision-language models and introduces PhysXVerse, the first large dataset of simulation-ready 3D assets with physical properties labeled. The approach matters for robotics, game development, and embodied AI—anywhere you need realistic 3D assets that move and deform correctly in simulation.
