Panoramas

The panorama viewer shows 360-degree photographs - the equirectangular pictures phones, 360 cameras and renderers make - drawn by the graphics card so they turn smoothly at any size. Drag, swipe, pinch or use the arrow keys to look around; zoom with the wheel; go fullscreen; let it turn slowly by itself until someone touches it.

Join several into a virtual tour: hotspots walk from room to room facing the right way, or open a note, a picture or a link; a floor plan shows where you stand and which way you look; a strip of scenes lets you jump anywhere. A small preview shows at once while the full picture loads. Turn on editing and double-click to place a hotspot, drag one to move it, and save the tour as JSON.
