Late last year Google discontinued active development of the company’s smartphone-based VR platform: Google Cardboard. At that time, the announcement was made that Google would open-source the project, an olive branch for developers hoping to continue improving the product. Google has now released the Cardboard Unity SDK to support these efforts.
