Extensible Immersive Virtual Environments for Large Tiled Video Walls

The intent of the work is to present an Immersive Virtual Environment (IVE) as a new abstracted management layer on top of the Scalable Adaptive Graphics Environment (SAGE) system, allowing the simplified management and linear scaling of multiple SAGE-driven video walls, and the creation and control of simple interactive scenarios. The framework exposes evolved Application Programming Interfaces (APIs) that are detached from the underlying system and can be used by mobile clients as well. Primitives offered to developers and content creators allow the definition of immersive cinematographic experiences using basic commands, which are synchronized on the whole IVE environment. A complete implementation of the system is described and then evaluated with the specific case of one physical installation
