Gravity Games: A Framework for Interactive Space Physics on Media Facades

We present a framework for setting up interactive three-dimensional outer-space simulations for media facades and other display environments. The core of this framework consists of a space simulator that is capable of efficiently rendering large amounts of objects and computing their physical behavior in real time. The extensible framework further allows to map 3D scenes to multiple displays and integrates interaction components via the TUIO protocol. We present a first use case that uses a mobile-phone GUI as a basis for user interaction on a projection-based 3D media facade. As an initial scenario, we use a generated space scene, which consists of asteroid belts with colliding space objects.
