Export 360 VR Experiences from CityEngine

A 360 VR Experience (.3vr) is a file format to publish and consume panoramic images of CityEngine scenes and web 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 360 VR Experience exporter is 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). The exported 360 VR Experience can then be consumed either locally or through the cloud after uploading.

To view 360 VR Experiences on desktop, mobile devices, and VR, see View 360 VR Experiences in the ArcGIS 360 VR web app.

Also you can create and publish 360 VR Experiences from web scenes directly in your web browser, see Create 360 VR Experiences from web scenes.

360 VR Experience export

The exporter converts CityEngine scenarios or layer compositions into 360 VR Experience scenarios; turning CityEngine camera bookmarks in to 360 VR Experience viewpoints. It then writes everything into a single 360 VR Experience (.3vr) file.

360 VR Experience export dialog

To create a 360 VR Experience, do the following:
