Rayform vs Lightwheel
Simulation-first infrastructure with its own assets and data, versus Rayform's processing of the recordings you already have.
What Lightwheel does.
Lightwheel builds infrastructure for robot learning in simulation: SimReady assets validated in Isaac Lab, egocentric human demonstration data, and policy evaluation. Its real-to-sim workflow turns a capture into a generated splat world and then into a USD scene.
Where they are strong
- A large library of physics-ready simulation assets in USD and MJCF.
- A full simulation workflow, from assets to evaluation.
- Demonstration data alongside the simulation tools.
How Rayform differs
- Lightwheel supplies assets and data of its own for simulation. Rayform works only on your recordings and gives them back to you.
- Rayform keeps real motion, interactions and robot state, aligned on one clock and one coordinate frame.

Choose Lightwheel when
- You want ready-made simulation assets and an evaluation harness.
- Most of your training happens in simulation.
Choose Rayform when
- You want to train on, or check your simulation against, what your own robots recorded.
