Parallax3D is a 3D rendering library with an API and shaders based on the very popular three.js <http://threejs.org> for Javascript/WebGL. The original Parallax project, based at <http://parallax3d.org/>, is almost entirely rewritten in Java, but specifically targets GWT (Google Web Toolkit), a system for converting Java to Javascript for creating web apps. A new fork at <https://github.com/realh/parallax> makes this great library available to Android Java developers, using OpenGL ES 2.0, and this app is the showcase for the demos that have been ported with it.
