We're using a cave-like setup (a single back-projected screen in an otherwise empty, dark room with head-tracking and stereo via shutter goggles) for experiments on the visual perception of depth. We need orthographic projection of the objects in certain cases to remove the perspective cue to depth (there are many depth cues, such as perspective, occlusion, and stereopsis, among others).

I'd been using vizcave because it seemed to be appropriate for our physical setup, but I'm not entirely clear what benefits I get from using vizcave when I don't want to link the tracker directly to the cave. I suppose that I can only get the appropriate units (i.e., 1 Vizard unit equals 1 meter) if I set up a cave with the right wall dimensions. But aside from that, I'm not sure it's worth setting up a cave.
