Google publishes open source Carboard SDK, allowing developers to bring virtual reality experiences to Google Cardboard

Present in 2014, Cardboard, a simple cardboard viewer that everyone can use to experience virtual reality. The year that followed, Google launched the application Carboard Camera that brought a kind of virtual reality to Android devices. Anyone who has already taken photos in a panoramic view knows first how to use this application: just hold the phone upright, activate the camera and take a full turn. The application will also record sounds while you take pictures, which will make the experience even more realistic.In 2015, the description of the application on Google’s download window was: with Cardboard Camera, take VR photos to relive highlights in virtual reality. listen to the sounds as if you were there and look around to see the scene from every angle. With 3D VR photos, nearby objects seem really close, and the more distant objects seem to be really far away. Whether it’s holiday memories or a family gathering, RV photos bring those moments back to life.

Of course, unlike video in virtual reality, the elements in the image remain static and appear more like a still image that includes the sounds of the scene.

It was in a statement that the company announced that it was making Cardboard open source:

Five years ago, we launched Google Cardboard, a simple cardboard viewer that everyone can use to experience virtual reality (VR). Introducing the Google I / O and running more than 15 million dunits worldwide, Cardboard has played an important role in the discovery of virtual reality through experiences such as YouTube and Expeditions. In many cases, this gave access to the virtual reality of people who could not have done otherwise.

With Cardboard and Google VR’s Software Development Kit (SDK), developers created and distributed virtual reality experiences on Android and iOS devices, enabling them to reach millions of users. While we have seen a decline in overall Cardboard usage over time and are no longer actively developing the Google VR SDK, we still see consistent use of entertainment and education experiences, such as YouTube and Expeditions. , and we want to make sure that Cardboard’s flawless functionality, accessible approach all of the virtual reality remains available.

Today, we are releasing the Open Source Cardboard Project to enable the developer community to continue to build Cardboard experiences and support their applications for an ever-increasing diversity of smartphone solutions and configurations. We believe that an open source model, with additional contributions from us, is the best way for developers to continue creating experiences for Cardboard. We have already seen the success of this approach with our Cardboard Manufacturer Kit, an open source project to enable third-party manufacturers to design and build their own unique compatible VR viewers, and we look forward to seeing where the developer community is going to lead Cardboard .

What is included in the open source project

Google provides libraries so that developers can create their Cardboard applications for iOS and Android and bring virtual reality experiences to Cardboard viewers. The open source project provides APIs for head tracking, lens distortion rendering, and entry management. Google has also included an Android QR code library, so applications can pair any Cardboard viewer without depending on the Cardboard application.

An open source model will allow the community to continue to improve Cardboard support and expand its functionality, for example by supporting new smartphone display configurations and Cardboard viewers as they become available. Google indicates its intention to continue contributing to the Open Source Cardboard project by publishing new features, including an SDK package for Unity.
