In a 3-pipe Super Desktop setup, each pipe will output a single video channel, such that each will take the place of one of the video channels in the single-pipe setup. That is, each pipe will output a single 1280x1024 or 1024x768 image, and these images must match in the overlap regions that are blended on the screen. It's not possible to open a single window, which spans multiple pipes, so you will have to setup the CAVELib configuration file to support multiple walls. Because the images should match exactly where they overlap, the geometry of the CAVE walls that cover corresponding regions must be exactly the same.
The easiest way to do this is to do the equivalent of the single projection plane configuration described earlier but now we will have three co-planar projection planes, like so:
For this setup the CAVELib configuration file will need to have three individual walls configured. Assuming 1280x1024 resolution per pipe, a 256 pixel overalp, and the same dimensions as before 150 deg total HFOV, 12' radius, 8' screen 1' of
