⚠️ Prerelease Software ⚠️

This project is in active alpha development. This means the API is unstable, features may be added or removed, and breaking changes are likely to occur frequently and without notice as the design is refined.

Newton is a GPU-accelerated physics simulation engine built upon NVIDIA Warp, specifically targeting roboticists and simulation researchers. It extends and generalizes Warp's existing warp.sim module, integrating MuJoCo Warp as a primary backend. Newton emphasizes GPU-based computation, differentiability, and user-defined extensibility, facilitating rapid iteration and scalable robotics simulation.

Newton is maintained by Disney Research, Google DeepMind, and NVIDIA.

See the installation guide for instructions on how to set up and get started.
