This demo shows how to use one device (equipped with an accelerometer) to explore in 3 dimensions an object shown on the screen of another device, using only off-the-shelf Web technologies.
- Load the 3D object (html5logo.html) on a given device, typically a regular computer browser that supports Server-Sent events.
- Load the 3D-explorer (3D.html) page on a device with an accelerometer and a browser supporting the accelerometer API (e.g. iPhone > 4, iPad, Firefox on Android, Android browser > 3.0)
- Move the second device and see how the object is animated on the first screen in sync
Under the hood
The movements of the second device are captured using W3C DeviceOrientation Events, sent to a server built using node.js that acts as a relay, dispatching them to the first device via Server-Sent events.
The HTML5 3D logo is built using HTML5’s canvas element.
