Unity Developers can take advantage of the Google Cast Remote Display API to extend their games onto a TV by use of the Google Cast Remote Display Plugin for Unity.
The plugin supports games built for iOS as well as Android.
This video shows a walk through of the Android based code lab available to teach how to integrate Google Cast Remote Display for Unity based games. The full code lab is available at https://www.code-labs.io/codelabs/cast-unity-plugin/ for developers to try.
The Google Cast Remote Display API allows developers to leverage the GPU power in mobile devices to render high frame-rate, responsive gaming and send it to a TV for large screen display. Using the Unity plugin simplifies the integration effort significantly and makes it easy to build a Google Cast enabled game.
