VR Juggler uses two types of files: Config Files and ChunkDesc Files.
Config Files are made of “Chunks” of information. For example, one chunk will describe the setup of a display device while another will describe the setup for a keyboard or tracking system. There will typically be several ready-made config files in the $VJ_BASE_DIR/share/Data directory, with names like simulator.config or C2_4wall.config.
ChunkDesc Files define the different kinds of chunks (ie. what kind of information a Keyboard chunk should have, or a Display chunk). The main ChunkDesc file for VR Juggler is usually $VJ_BASE_DIR/share/Data/chunksDesc.
