Cupola VR Viewer

Daniel Andersen

Cupola VR Viewer connects the Oculus Rift virtual reality headset to browser-based VR environments. It allows developers to take advantage of WebGL for virtual reality and use Javascript libraries like three.js, while also offering low-latency head-tracking. Cupola acts as a container for remotely-hosted pages (such as WebGL demos) inside a webview, uses Chrome's USB API to get orientation data from the Rift hardware, and uses window.postMessage to make the orientation available to the page inside the webview. Several parts of the C++ Oculus SDK have been reimplemented in Javascript to convert the bytes received over USB into usable orientation values. If you have calibrated your Oculus Rift, you can drag and drop your configuration files into the Cupola viewer to calibrate it. In order to work with this app, the virtual environment must be Cupola-enabled.
