Ah, the power of WebGL. This sample provides a quick example of integrating ThreeJS into a Crosswalk application.
This application is part of the Crosswalk samples.
The steps for setting up an environment for Crosswalk are explained in detail in the Getting started tutorial.
WebGL on Android
Once you've set up the Crosswalk Android packaging dependencies, follow the steps in Run on Android to install and run the WebGL sample on Android.
The quick version is that you can build the WebGL apk with:
> <crosswalk-app-tools>/src/crosswalk-pkg --crosswalk=<crosswalk version> \ --platforms=android <path to crosswalk-samples>/webgl
<crosswalk-app-tools> refers to the directory where you downloaded crosswalk-app-tools.
Then install the apk file on Android:
> adb install org.xwalk.webgl*.apk
