As the rumours have suggested, Google is bringing its Cardboard SDK to iOS developers. This means, developers of iPhone apps can create apps that will work with Google's virtual reality viewer. The Google Cardboard is a low-cost viewer that lets you slot in your smartphone into the front of the viewer to bring both virtual and augmented reality experiences to you via apps.
Aside from launching the SDK for iOS, Google's also introduced VR view, a feature to let developers include immersive content within apps and websites. It can turn images and videos into 360-degree VR images and videos that can be viewed on the desktop or with a phone attached to a Cardboard viewer. Both the SDK and the tools needed to create VR views are available starting today.
