orthographic projection in a head-tracked cave environment

[michaelrepucci]

So that means I would have to compute the left and right orthographic frustums on each frame? In that case, a cave with just one wall wouldn't be very useful. Or does the cave do something else special?

I'm not sure what you are asking here. If you want to use an orthographic projection matrix then you need to apply it yourself. The number of walls has nothing to do with this. Out of curiosity, why do you need to use an orthographic projection in your CAVE?
