The instantreality framework is a high-performance Mixed-Reality-system, which combines various Input- and Output devices, application and rendering components and provides a single and consistent interface for AR/VR developments. Those components have been developed at the Fraunhofer IGD in close cooperation with industrial partners. The framework offers a comprehensive set of features to support classic Virtual Reality and advanced Augmented Reality equally well. The goal was to provide a very simple application interface as a superset of X3D, while still including the latest research results in the fields of high-realistic rendering, 3D user interaction and total-immersive display technology.
