ImmersiON-VRELIA has already made public its SDK for Unity, with which it will be possible to start developing software compatible with the GO viewer and, very soon, with the rest of the models.
At the moment, this SDK is for use together with the Unity 3D graphics engine on Android through a plugin, and it is in alpha version and in continuous development and improvement. To get it, you just have to register as a developer on the ImmersiON-VRELIA website, in the Community -> Developers section, where you can download a version with fully functional example scenes and video tutorials that explain its use in detail.
The SDK is designed for quick and easy use that allows you to adapt any Unity content with just drag and drop in our scene or some small modifications in more complex projects. It also includes very interesting options such as the ability to view and configure various parameters in real time during the execution of applications and the Unity editor, dynamic convergence and many more options that will be included in the next revisions.
