360 Panorama Photo Sphere – Visual Composer Addon is a filter that allows you to display 360×180 degree panoramas.
Photo Sphere Viewer is pure JS and based on Three.js, allowing very good performances on WebGL enabled systems (most recent browsers) and reasonably good performances on other systems supporting HTML Canvas.
Photo Sphere is based on the JavaScript library [Photo Sphere Viewer]
