ArcGIS 360 VR Experience (3VR) is a file format to publish and consume panoramic images of CityEngine scenes. These panoramic images are consumable in browsers (users look around with mouse), mobiles (users look around with gyro/touch), and virtual reality (VR) headsets (users look around by turning their head). At its core, the CityEngine 3VR exporter is basically an automated way to take a series of viewport snapshots based on camera bookmarks. These snapshots are combined into panoramic images (one for each bookmark). Afterwards, the resulting 3VR file is ready to be consumed locally or via the cloud after uploading.
