A distributed visualization module and its applications using tiled display wall

Abstract

In recent years, the use of large high-resolution display systems, usually implemented through tiled display walls, has been increasing in many areas of industry. In the virtual reality area, distributed visualization using PC clusters is generally used and it is necessary to design a synchronization procedure and to define appropriate simulation parameters to be synchronized within it. In this work, we developed a distributed visualization module to synchronize tiled scene contents generated by the open-source graphics engine, using the consistent shared-object mechanism which can be interoperable with the application-specific scene graph. We then applied this module to a couple of virtual reality applications using a DLP-Cube based tiled display system in order to evaluate its visualization result and real-time performance.
