Watch NVIDIA CEO Jensen Huang recap all the news from GTC: Together, these new capabilities brought to life by Omniverse deliver a simulation experience that is virtually indistinguishable from reality.
Omniverse enables DRIVE Sim to simultaneously simulate multiple cameras, radars and lidars in real time, supporting sensor configurations from Level 2 assisted driving to Level 4 and Level 5 fully autonomous driving.

While the timing and latency of such architectures may be good enough for consumer games, designing a repeatable simulator for autonomous vehicles requires a much higher level of precision and performance.

Most applications for generating virtual environments are targeted to systems with one to two GPUs, such as PC games. For instance, USD makes it easy to define the state of the vehicle (position, velocity, acceleration) and trigger changes based on its proximity to other entities such as a landmark in the scene.Īlso, the framework comes with a rich toolset and is supported by most major content creation tools. USD provides a high level of abstraction to describe scenes in DRIVE Sim. Universal Scene DescriptionĭRIVE Sim is based on Universal Scene Description, an open framework developed by Pixar to build and collaborate on 3D content for virtual worlds.
Nighttime parking scenarios show the benefit of ray tracing for complex shadows generated by dynamic light sources. This leads to shadows that appear softer and are much more accurate. In the night parking example from the video, the shadows from the lights are rendered directly instead of being pre-baked. RTX enables high-fidelity shadows to be computed at run-time. However, to provide a dynamic environment for simulation, pre-baking isn’t possible. Typically in virtual environments, shadows are pre-computed or pre-baked. The Mercedes EQS shows the complexity of reflections enabled with ray tracing, including reflections of objects that are in the scene, but not in the frame. This also applies to other reflective surfaces such as wet roadways, reflective signs and buildings. In the video, the vehicles show complex reflections of objects in the scene - including those not directly in the frame, just as it would in the real world. The capability to simulate light in real time has significant benefits for autonomous vehicle simulation. And the Omniverse RTX renderer coupled with NVIDIA RTX GPUs enables ray tracing at real-time frame rates. Ray tracing is perfectly suited for this, providing realistic lighting by simulating the physical properties of light. This is especially critical for simulating sensors, which requires modeling rays beyond the visible spectrum and accurate timing between the sensor scan and environment changes. Physically Accurate Sensor SimulationĪutonomous vehicle simulation requires accurate physics and light modeling. The hardware, software, sensors, car displays and human-machine interaction were all implemented in simulation in the exact same way as the real world, enabling bit- and timing-accurate simulation. To achieve the real-world replica of the testing loop, the real environment was scanned at 5-cm accuracy and recreated in simulation. It includes Highways 101 and 87 and Interstate 280, with traffic lights, on-ramps, off-ramps and merges as well as changes to the time of day, weather and traffic. The video shows a digital twin of a Mercedes-Benz EQS driving a 17-mile route around a recreated version of the NVIDIA campus in Santa Clara, Calif. It enables ray-traced, physically accurate, real-time sensor simulation with NVIDIA RTX technology. Omniverse was architected from the ground up to support multi-GPU, large-scale, multisensor simulation for autonomous machines. DRIVE Sim leverages the cutting-edge capabilities of the platform for end-to-end, physically accurate autonomous vehicle simulation.
The line between the physical and virtual worlds is blurring as autonomous vehicle simulation sharpens with NVIDIA Omniverse, our photorealistic 3D simulation and collaboration platform.ĭuring the GPU Technology Conference keynote, NVIDIA founder and CEO Jensen Huang showcased for the first time NVIDIA DRIVE Sim running on NVIDIA Omniverse.
