Rayform vs NVIDIA NuRec
Free libraries to reconstruct a scene for Isaac Sim, versus a managed service that reconstructs, aligns, labels and serves all your recordings.
What NVIDIA NuRec does.
Omniverse NuRec reconstructs scenes from camera or LiDAR data into Gaussian-splat scenes packaged as OpenUSD, and Isaac Sim renders them. 3DGRUT, NVIDIA's open-source trainer, exports scenes in the format Isaac Sim reads.
They work together. We plan to export reconstructed scenes in a form NuRec and Isaac Sim can load, so your processed recordings drop into Isaac.
Where they are strong
- Free, with an open-source trainer.
- Built into Isaac Sim.
- Handles distorted and wide-angle cameras.
How Rayform differs
- NuRec is a set of libraries you run yourself, one scene at a time. Rayform runs reconstruction as a service across every recording you upload.
- Rayform keeps the reconstruction aligned with your sensor logs and robot state, labels interactions, and makes everything searchable.

| Export to training formatsLeRobot, RLDS or WebDataset for training; USD for simulators. | Yes | Partly |
| Self-serve accessStart without a sales call. | Partly | Yes |
Choose NVIDIA NuRec when
- You have a few scenes, the GPUs and the people to run reconstruction, and you only need them in Isaac Sim.
Choose Rayform when
- You have many recordings and want them processed the same way, every time.
- You need training data, not only simulation scenes.
