The State of Simulation for Physical AI: An Overview

Newton is an open-source, GPU-accelerated physics engine developed by NVIDIA, Google DeepMind, and Disney Research, and managed by the Linux Foundation. Built on NVIDIA Warp and OpenUSD, it integrates MuJoCo Warp as a key physics backend. Newton provides multiple solver implementations like SolverMuJoCo, SolverFeatherstone, SolverSemiImplicit, SolverXPBD, SolverKamino, SolverVBD, SolverImplicitMPM, and SolverStyle3D, each with different capabilities for various physical systems.
