This example lets you test Photo Sphere Viewer by loading a predefined panorama (the one which was already loaded by the other example). To see this panorama, just hit the link below: currently, the div has a height of 0 pixel but Photo Sphere Viewer will increase it to 500 pixels.
Note that the panorama is here given as a relative path, but you can give to Photo Sphere Viewer an absolute one or an URL pointing to another website if this website allows CORS.
Have you got a panorama stored on your computer? Try to read it with Photo Sphere Viewer with the following button. The code uses the FileReader API and is very simple to write (you can retrieve the source code in the example1.js file).
