Oculus Releases Mobile SDK 0.6.0

Last month saw virtual reality (VR) specialist Oculus VR release the Beta version of its software development kit (SDK) for the Oculus Rift head-mounted display (HMD), which arrived in time for the release window and recommend specs for the device. But the company hasn’t forgotten about its Mobile SDK for the Gear VR smartphone-based device. Today sees Oculus VR release Mobile SDK 0.6.0, bringing with it a host of new features, improvements and fixes to the kit. A full changelog can be seen below.

Gear VR for Samsung Galaxy S6

As Oculus VR reveals in an update blog, the latest version of the SDK makes some significant changes that ‘necessitate updates to the VRLib structure, native app interface, and development workflow.’ VRlib, for example has be restructured into ‘three separate libraries’: LibOVR for the Oculus Library, VrApi for the minimal API for VR, and VrAppFramework for the application framework used by native apps. Elsewhere, the Vr App Interfacte is now a part of the VrAppFramework and is said to be simplified with a clearly-defined lifecycle.

There are also some changes to Unity integration. Namely, Oculus Runtime is no longer required for mobile development, and the SDK is synced with SDK on PC.

VRFocus will continue to follow Oculus VR closely, reporting back with any further updates on its work.
