Photo Sphere Viewer

Photo Sphere Viewer is a JavaScript library that allows you to display 360×180 degrees panoramas on any web page. Panoramas must use the equirectangular projection and they can be taken with Photo Sphere, the camera mode brought by Android 4.2 Jelly Bean.

Photo Sphere Viewer uses the Three.js library, so nothing is required for your visitors except for a browser compatible with canvas or, better, WebGL.

How To Use It

1. Include the three.min.js and photo-sphere-viewer.min.js files into your page.
2. Create a div in the size you want for your panorama.

3. In JavaScript, create a new PhotoSphereViewer object. You must pass it an object containing at least two parameters for the panorama. Here is the list of available parameters.

   • panorama (required): the path to the panorama.
   • container (required): the div in which the panorama will be displayed.
   • autoload (optional, default to true): true to automatically load the panorama, false to load it later (with the .load() method).
   • usexmpdata (optional, default to true): true if Photo Sphere Viewer must read XMP data, false if it is not necessary.
   • cors_anonymous (optional, default to true): true to disable the exchange of user credentials via cookies, false otherwise.
   • pano_size (optional, default to null) The panorama size, if cropped (unnecessary if XMP data can be read).
   • default_position (optional, default to {}) Defines the default position, the first point seen by the user (e.g. {long: Math.PI, lat: Math.PI/2}).
   • min_fov (optional, default to 30): the minimal field of view, in degrees, between 1 and 179.
   • max_fov (optional, default to 90): the maximal field of view, in degrees, between 1 and 179.
   • allow_user_interactions (optional, default to true): If set to false, the user won't be able to interact with the panorama (navigation bar is then disabled).
   • allow_scroll_to_zoom (optional, default totrue): It set tofalse`, the user won't be able to scroll with their mouse to zoom.
   • tilt_up_max (optional, default to Math.PI/2): The maximal tilt up angle, in radians.
   • tilt_down_max (optional, default to Math.PI/2): The maximal tilt down angle, in radians.
   • min_longitude (optional, default to 0): The minimal longitude to show.
   • max_longitude (optional, default to 2π): The maximal longitude to show.
   • zoom_level (optional, default to 0): The default zoom level, between 0 and 100.
   • long_offset (optional, default to PI/360): the longitude to travel per pixel moved by mouse/touch.
   • lat_offset (optional, default to PI/180): the latitude to travel per pixel moved by mouse/touch.
   • time_anim (optional, default to 2000): the panorama will be automatically animated after time_anim milliseconds (indicate false to deactivate it).
   • reverse_anim (optional, default to true) true if horizontal animation must be reversed when min/max longitude is reached (only if the whole circle is not described).
   • anim_speed (optional, default to 2rpm): animation speed in radians/degrees/revolutions per second/minute.
   • vertical_anim_speed (optional, default to 2rpm): vertical animation speed in radians/degrees/revolutions per second/minute.
   • vertical_anim_target (optional, default to 0): latitude to target during the autorotate animation, default to the equator.
   • navbar (optional, default to false): set to true, a navigation bar will be displayed.

   • navbar_style (optional, default to {}): a custom style for the navigation bar. See the list below to know what properties are available.

     • backgroundColor: the navigation bar background color (default to rgba(61, 61, 61, 0.5)).
     • buttonsColor: the buttons foreground color (default to rgba(255, 255, 255, 0.7)).
     • buttonsBackgroundColor: the buttons background color (default to transparent).
     • activeButtonsBackgroundColor: the buttons background color when they are active (default to rgba(255, 255, 255, 0.1)).
     • buttonsHeight: buttons height in pixels (default to 20).
     • autorotateThickness: autorotate icon thickness in pixels (default to 1).
     • zoomRangeWidth: zoom range width in pixels (default to 50).
     • zoomRangeThickness: zoom range thickness in pixels (default to 1).
     • zoomRangeDisk: zoom range disk diameter in pixels (default to 7).
     • fullscreenRatio: fullscreen icon ratio (default to 4/3).
     • fullscreenThickness: fullscreen icon thickness in pixels (default to 2).

     Colors can be in rgb(), rgba() or hexadecimal format, and the keyword transparent is accepted.

   • loading_msg (optional, default to Loading…): Loading message.
   • loading_img (optional, default to null): the path to the image shown during the loading.
   • loading_html (optional, default to null) An HTML loader (element to append to the container or string representing the HTML).
   • size (optional, default to null): the final size of the panorama container (e.g. {width: 500, height: 300}).
   • onready (optional, default to null) Function called once the panorama is ready and the first image is displayed.

You can find a basic example of use in the file example.html. The example1.html is a more complete (and more interesting) example.

If your panorama is taken with Google's Photo Sphere, usexmpdata must be set to true, unless it is not cropped.
