Unity is a game development engine, kind of like a software-building kit. Developers use it to create 2D and (mostly) 3D graphics environments.

The world's most popular game engine, Unity, is getting a lot smarter thanks to a partnership with IBM to bring the fabulous Watson to VR/AR.

Unity Technologies has announced plans to introduce Project Tango support in a future version of the Unity video game engine.

That's where Unity Learn is a huge help. It's a website run by Unity Technologies that offers hundreds of hours of professionally made video tutorials that dive into every facet of game development.

Google said that it opened its Google Maps doors to developers of mobile augmented reality games, granting access to all that mapped data.
