There is an easy way to calculate the frustum; it's a fairly
straightforward trig problem. If you need help with it, then see the
TrackballManipulator code.

Hi,
is there any easy way to focus a object?
I'm able to center my camera onto the object but i want to zoom in as much as possible.
In some way i must fit the bounding sphere of my object into the camera frustum.
I think i have to set the frustum my self but perhaps there is an easy way to calculate the frustum?
Thank you!
Cheers,
Johannes
