JSON Configuration File Options

General options

type

This specifies the panorama type. Can be equirectangular, cubemap, or multires. Defaults to equirectangular.

title

If set, the value is displayed as the panorama’s title. If no title is desired, don’t set this parameter.

author

If set, the value is displayed as the panorama’s author. If no author is desired, don’t set this parameter.

basePath

This specifies a base path to load the images from.

autoLoad

When set to true, the panorama will automatically load. When false, the user needs to click on the load button to load the panorama. Defaults to false.

autoRotate

Setting this parameter causes the panorama to automatically rotate when loaded. The value specifies the rotation speed in degrees per second. Positive is counter-clockwise, and negative is clockwise.

autoRotateInactivityDelay

Sets the delay, in milliseconds, to start automatically rotating the panorama after user activity ceases. This parameter only has an effect if the autoRotate parameter is set.

autoRotateStopDelay

Sets the delay, in milliseconds, to stop automatically rotating the panorama after it is loaded. This parameter only has an effect if the autoRotate parameter is set.

fallback

If set, the value is used as a URL for a fallback viewer in case Pannellum is not supported by the user’s device. The user will be given the option to click a link and visit this URL if Pannellum fails to work.

showZoomCtrl

If set to false, the zoom controls will not be displayed. Defaults to true.

keyboardZoom

If set to false, zooming with keyboard will be disabled. Defaults to true.

mouseZoom

If set to false, zooming with mouse wheel will be disabled. Defaults to true.

showFullscreenCtrl

If set to false, the fullscreen control will not be displayed. Defaults to true. The fullscreen button will only be displayed if the browser supports the fullscreen API.

yaw

Sets the panorama’s starting yaw position in degrees. Defaults to 0.

pitch

Sets the panorama’s starting pitch position in degrees. Defaults to 0.

hfov

Sets the panorama’s starting horizontal field of view in degrees. Defaults to 100.

minYaw and maxYaw

Sets the minimum / maximum yaw the viewer can be centered at, in degrees. Defaults to -360 / 360, i.e. no limit.

minPitch and maxPitch

Sets the minimum / maximum pitch the viewer can be centered at, in degrees. Defaults to -85 / 85.

minHfov and maxHfov

Sets the minimum / maximum horizontal field of view, in degrees, that the viewer can be set to. Defaults to 50 / 120.

compass

If true, a compass is displayed. Defaults to false.

northOffset

Set the offset, in degrees, of the center of the panorama from North. As this affects the compass, it only has an effect if compass is set to true.

preview

Specifies a URL for a preview image to display before the panorama is loaded.

hotSpots

This specifies an array of hot spots that can be links to other scenes, information, or external links. Each array element has the following properties.

pitch

Specifies the pitch portion of the hot spot’s location.

yaw

Specifies the yaw portion of the hot spot’s location.

type

Specifies the type of the hot spot. Can be scene for scene links or info for information hot spots. A tour configuration file is required for scene hot spots.

text

This specifies the text that is displayed when the user hovers over the hot spot.

URL

If specified for an info hot spot, the hot spot links to the specified URL. Not applicable for scene hot spots.

sceneId

Specifies the ID of the scene to link to for scene hot spots. Not applicable for info hot spots.

targetPitch

Specifies the pitch of the target scene.

targetYaw

Specifies the yaw of the target scene.

targetHfov

Specifies the HFOV of the target scene.

hotSpotDebug

When true, the mouse pointer’s pitch and yaw are logged to the console when the mouse button is clicked. Defaults to false.

sceneFadeDuration

Specifies the fade duration, in milliseconds, when transitioning between scenes. Not defined by default. Only applicable for tours. Only works with WebGL renderer.

equirectangular specific options

panorama

Sets the URL to the equirectangular panorama image. This is relative to basePath if it is set, else it is relative to the location of pannellum.htm. An absolute URL can also be used.

haov

Sets the panorama’s horizontal angle of view, in degrees. Defaults to 360. This is used if the equirectangular image does not cover a full 360 degrees in the horizontal.

vaov

Sets the panorama’s vertical angle of view, in degrees. Defaults to 180. This is used if the equirectangular image does not cover a full 180 degrees in the vertical.

vOffset

Sets the vertical offset of the center of the equirectangular image from the horizon, in degrees. Defaults to 0. This is used if vaov is less than 180 and the equirectangular image is not cropped symmetrically.

ignoreGPanoXMP

If set to true, any embedded Photo Sphere XMP data will be ignored; else, said data will override any existing settings. Defaults to false.

cubemap specific options

cubeMap

This is an array of URLs for the six cube faces in the order front, right, back, left, up, down. These are relative to basePath if it is set, else they are relative to the location of pannellum.htm. Absolute URLs can also be used.

multires specific options

multiRes

This contains information about the multiresolution panorama in sub-keys.

basePath

This is the base path of the URLs for the multiresolution tiles. It is relative to the regular basePath option if it is defined, else it is relative to the location of pannellum.htm. An absolute URL can also be used.

path

This is a format string for the location of the multiresolution tiles, relative to multiRes.basePath, which is relative to basePath. Format parameters are %l for the zoom level, %s for the cube face, %x for the x index, and %y for the y index. For each tile, .extension is appended.

fallbackPath

This is a format string for the location of the fallback tiles for the CSS 3D transform-based renderer if the WebGL renderer is not supported, relative to multiRes.basePath, which is relative to basePath. The only format parameter is %s, for the cube face. For each face, .extension is appended.

extension

Specifies the tiles’ file extension. Do not include the ..

tileResolution

This specifies the size in pixels of each image tile.

maxLevel

This specifies the maximum zoom level.

cubeResolution

This specifies the size in pixels of the full resolution cube faces the image tiles were created from.

Dynamic content specific options

Currently, only equirectangular dynamic content is supported.

dynamic

The panorama source is considered dynamic when this is set to true. Defaults to false. This should be set to true for video.

Additional information for tour configuration files

A tour configuration file contains two top level properties, default and scenes. The default property contains options that are used for each scene, but options specified for individual scenes override these options. The default property is required to have a firstScene property that contains the scene ID for the first scene to be displayed. The scenes property contains a dictionary of scenes, specified by scene IDs. The values assigned to these IDs are specific to each scene.
