Attaching mass and spring properties to splats enables physics simulation
  • Each splat can be enriched with a mass value and linked to neighbouring splats via virtual springs.
  • This lightweight physics layer allows simple dynamics such as gravity, collisions, and elastic deformation without a full engine.
  • Because the physics is baked into the same data structure used for rendering, updates remain real‑time.
  • Early prototypes show plausible object interactions, opening doors for interactive design tools.

Integrating Physics into World Models

Adding dynamics and force reasoning to generative 3-D models is essential for applications like architecture and robotics. The team explores two pathways: attaching physical properties directly to splats and distilling classical physics engine simulations into neural weights. Accurate physics remains a hard problem, especially when models must generalise to unseen forces.
