The CaveUT system: immersive entertainment based on a game engine

We describe recent developments in the CaveUT software, which supports immersive virtual reality installations based on the Unreal Tournament game engine. CaveUT implements several high-end VR features such as real-time stereoscopy with head and hand tracking. We demonstrate the use of CaveUT in the SAS Cube™, a PC-based CAVE™-like immersive four-screen display. One of the main advantages of the system is to support fully immersive VR while retaining the game engine's advanced features for interaction and behavioral (or AI) systems. We illustrate the use of CaveUT on two installations: an artistic VR installation and an immersive interactive storytelling system.
