Students lead this effort to recreate Google Earth VR (which currently only supports immersive presentation in VR headsets) for exploration in the VARLab’s vDen, our CAVE VR system. Using Unity, Cesium, Google’s photorealistic 3D Map Tiles, and public APIs, EarthXR lets us explore the Earth in 3D, see Street View, search for locations, bookmark places, and view live 3D aircraft data. One goal for this project is to serve as a digital twin of the Earth by including live weather, traffic, and place data. EarthXR’s design allows it to be deployed to many XR systems, including alternative 3D displays, VR headsets, and mixed reality devices.
