Methods

Presentation

Many methods are available to control the viewer from your application. The full list of methods is available in the API Reference.

Modular architecture

Photo Sphere Viewer is internally splitted in multiple components, this has an impact on where are located each method. For example, the methods to control the navbar are in the navbar object.

Read more about reusable components.

It is good practice to wait for the ready event before calling any method.

viewer.addEventListener('ready', () => {
  viewer.rotate({
    textureX: 1500,
    textureY: 1000,
  });
}, { once: true });

Main methods

This section describes the most useful methods available.

Positions definitions

Some methods takes positionnal arguments, this is either on combination yaw and pitch (radians or degrees) or textureX and textureY properties, corresponding to the pixel position on the source panorama file.

When using a cubemap you will also have to provide textureFace.

animate(options): Animation

• options: AnimateOptions

Rotate and zoom the view with a smooth animation. You can change the position (yaw, pitch or textureX, textureY) and the zoom level (zoom).

The speed option is either a duration in milliseconds or a string containing the speed in revolutions per minute (2rpm).

The method returns a Animation object which is a standard Promise with an additional cancel method.

viewer.animate({
  yaw: Math.PI / 2,
  pitch: '20deg',
  zoom: 50,
  speed: '2rpm',
})
  .then(() => /* animation complete */);

destroy()

Remove the viewer from the page and free the memory used by Three.js.

getPlugin(pluginId): PluginInstance

Return the instance of plugin, more details on the dedicated page.

getPosition(): Position

Return the current position of the view.

getZoomLevel(): number

Return the current zoom level between 0 and 100.

rotate(position)

Immediately rotate the view without animation.

// you can also use yaw and pitch
viewer.rotate({
    textureX: 1500,
    textureY: 600,
});

setOption(option, value)

Update an option of the viewer. Some options cannot be changed : panorama, panoData, container, adapter and plugins.

viewer.setOption('fisheye', true);

setOptions(options)

Update multiple options at once.

viewer.setOptions({
    fisheye: true,
});

setPanorama(panorama[, options]): Promise

• options: PanoramaOptions

Change the panorama image with an optional transition animation (enabled by default).

The method returns a Promise resolved when the new panorama has finished loading.

viewer.setPanorama('image.jpg')
  .then(() => /* update complete */);

viewer.setPanorama('image.jpg', { transition: false });

viewer.setPanorama('image.jpg', {
  caption: 'The new caption',
  position: { yaw: 0, pitch: 0 },
  transition: {
    rotation: false,
    effect: 'black',
  },
  // more options in the API doc
});

zoom(level) | zoomIn([step = 1]) | zoomOut([step = 1])

Change the zoom level without animation.
