Key Features

Virtual Community integrates geospatial data with generative models to create interactive, scalable open-world scenes with socially grounded agent communities.

Scalable Simulation-Ready Scenes

A fully automatic online pipeline that creates 3D scenes with real-world geospatial data and generative models.

Real World Grounded Geospatial Scenes
Geospatial data ensures the diversity and scale of outdoor 3D scenes.
Automatic Semantic Annotations
Locations and objects automatically labeled within scenes
Semantic Annotations Example
Interactive Indoor Scenes and Objects
Indoor scenes and objects created according to place annotations.

Agent Community

Leverage foundation models and real-world annotations to generate communities and simulate with Genesis physics engine.

Agent Community Generation
LLM-powered profiles with personalities and social connections
Automatic traffic system
pedestrian flow, vehicle flow, transit system
Human and robot interaction
Genesis powers physically realistic robot interactions in the community
Robot simulation with contact visualized
