With the recent availability of multiple graphics cards in standalone systems the method can also be implemented on a single computer system where memory bandwidth is much higher compared to off-the-shelf networking technology. Multi-frame rate rendering is naturally implemented on a graphics cluster. The results of a user study confirm that multi-frame rate rendering can significantly improve the interaction performance. The resulting color and depth images of both render processes are composited, by optical superposition or digital composition, and displayed. Multi-frame rate rendering is a parallel rendering technique that renders interactive parts of a scene on one graphics card while the rest of the scene is rendered asynchronously on a second graphics card. Similar such displays are investigated at Princeton University, the University of North Carolina at Chapel Hill, Stanford University, The University of Kentucky and the National Center for Supercomputing (NCSA) at the University of Illinois at Urbana Champaign. Fraunhofer Institute of Germany, located only a few miles away from the Mercedes manufacturing station at Stuttgart, has at least six such displays, all of which are used to visualize large data sets generated during the design of automobiles or for virtual auto crash tests.
Such VR environments are also used for entertainment purpose, for example, by Disney.
Such displays are also used to create high quality virtual reality (VR) environments used to simulate sophisticated training environments for pilots. Several such displays are used at Sandia National Laboratory, Lawrence Livermore National Laboratory and Argonne National Laboratory for visualizing very large scientific data, in the order of petabytes (10 15 bytes) and higher (10 18 bytes), and also for holding meetings between collaborators located all around the country. both of which are desirable for applications like scientific visualization and tele-collaboration. Large Tiled Display at Argonne National Laboratory: 5 × 3 array of fifteen projectors.
