Using vizcave without tracking

[pcatalano]

Hello,

An application I am developing would benefit from the vizcave routines but will have a fixed viewer position so will not need tracking. However, I can't figure out how to use vizcave without tracking. Since I already have routines in place to do keyboard and mouse navigation, I don't need any of the keyboard/mouse tracking routines, but if I use one of them (viztracker.KeyboardPos for instance) it gets in the way of my existing navigation routines.

How do I set up a cave in Vizard with a static eye position but still allow navigation of the environment using custom controls (that have already been implemented)?
