Street View Events

Spark icon

Page Summary

This example demonstrates tracking Street View events to monitor the performance of the StreetViewPanorama object.
The sample code displays a Street View panorama alongside a panel that updates with real-time data like position, POV, and pano ID.
Users can interact with the panorama, and the associated data will be reflected in the panel.
The example utilizes event listeners like pano_changed, links_changed, position_changed, and pov_changed to capture and display relevant data.

This example displays a Street View panorama, alongside a window that tracks several types of data associated with Street View events. This data can be tracked to better understand the performance of the underlying StreetViewPanorama object.
