Summary
NVIDIA Omniverse is an open platform for building and operating real-time 3D simulation and collaboration applications, built on the OpenUSD (Universal Scene Description) standard. It provides a compute platform for developing industrial digital twins, physically accurate simulations, and robot/autonomous vehicle training environments through a suite of SDKs, renderers, and simulation engines. Omniverse serves as the foundation layer for NVIDIA-Isaac-Sim and the broader industrial AI simulation ecosystem.
Detail
Purpose
Omniverse solves the challenge of collaborative, physically accurate 3D world simulation by providing a shared USD-based composition layer that enables different simulation domains (physics, rendering, AI) to operate simultaneously on the same scene. It enables industrial customers to build digital twins of factories, cities, and infrastructure for AI training, operational planning, and visualization.
