Hybrid Particle-Voxel Dynamics for Multimodal 3D World Simulation
3D World Simulator is introduced, an action-conditioned multimodal world modeling framework that jointly predicts appearance, geometry, and tactile observations from a unified 3D representation that enables scalable data generation for policy training and evaluation using tactile and multi-view visual observations.
