URL Configuration Parameters

URL parameters are used to configure Pannellum. If an equirectangular image is being used without some of Pannellum’s more advanced features, Pannellum can be configured with just URL parameters; else, a JSON configuration file needs to be used with the config.

config

Specifies the URL of a JSON configuration file.

Other parameters

A subset of the JSON configuration file options can be used as URL parameters. These include panorama, config, author, title, hfov, minHfov, maxHfov, pitch, minPitch, maxPitch, yaw, minYaw, maxYaw, haov, vaov, vOffset, autoLoad, autoRotate, firstScene, ignoreGPanoXMP, preview, and fallback.
