vizcave not working properly - coordinate systems

[jpriede]

Hello.

I created a cave, and Keyboard6DOF tracker. I then enabled drawWalls, to debug.

When I press arrow keys to move the eyes closer to the CAVE wall, the field of view widens, as expected; however, the eyes do not move within the cave, and results in seeing the SIDE walls as well as the front wall.

It appears to me, that rather than moving the eyepoint within the CAVE, this is moving the actual cave environment, but keeping the eyes stationary within the world.

This results in the correct relative field of views for the eyes, but doesn't make any sense in terms of tracking.

Clearly, a tracking system is tracking a moving eyepoint within a stationary cave, not tracking a moving cave with stationary eyepoint.

This is making it rather confusing to create a properly functioning CAVE environment. Can anyone shed some light on this? Is there some obscure reason it is implemented in this way that I am not aware of?
