It had already open-sourced the actual Cardboard VR viewer by posting its technical specifications for anyone to download, so it is nice to see Google open up the software as well.
Google says its shipped more than 15 million units worldwide, but that its seen usage of Cardboard decline over time.
Now, though, that trend is officially over, with seemingly no way to buy Oculus Gear VR in the US and Google discontinuing Daydream.
Google says it will contribute to the Cardboard open source project by adding new features, but beyond committing to adding an SDK package for Unity, it doesnt specify what those features might be. If you want to check out the project for yourself, Google has shared developer documentation and uploaded the Cardboard SDK to a GitHub repo.
