Google today announced a new program in which it will work with developers who are building applications for Google’s Daydream high-quality mobile virtual reality (VR) platform. Developers can now apply to become part of the new Daydream Access Program (DAP). That way, they won’t have to wait until early 2017 to submit applications to Google alongside other developers.

Google also announced that it’s launched the Google VR software development kit (SDK) out of beta. That SDK, previously known as the Cardboard SDK for building apps for the Google Cardboard (VR) headset, was updated with Daydream support at the Google I/O developer conference in May alongside the launch of the Google VR native development kit (NDK).

“Our updated SDK simplifies common VR development tasks so you can focus on building immersive, interactive mobile VR applications for Daydream-ready phones and headsets, and supports integrated asynchronous reprojection, high fidelity spatialized audio, and interactions using the Daydream controller,” Google VR product manager Nathan Martz wrote in a blog post.

As promised, the Google VR SDK now features a native integration of the Unity game engine. The binaries are available from Unity’s website. Code for the native integration of the Unreal Engine game engine has been updated as well.

As for phones that will be able to run Daydream apps, the headset for use with the phones, and the corresponding controller, they’re coming soon, Martz wrote.
