The panorama must be an equirectangular projection (opens new window) of your photo. You can also use cubemap projection with a special syntax.

Cropped panoramas

If your image is not covering a full 360°×180° sphere, it will be deformed. You can fix it by providing cropping data.


Previous version of Photo Sphere Viewer had a caching system, which was buggy and thus disabled by default.

Photo Sphere Viewer 4 uses THREE.js Cache (opens new window), enabled by default. You can disable this cache by calling THREE.Cache.enabled = false; after importing Photo Sphere Viewer.
