Hi,
To move around my scene I created a behaviour similar to OrbitBehavior. So focal
point is equivalent to the point around which OrbitBehavior orbits
(centerOfRotation). The user is allowed to choose the focal point - the area of
interest, what they zoom into, rotate around - and they can see up to radius
units behind the focal point. If you are using a different system of navigation
John Wright's suggestion is more appropriate:
> There isn't a true (optical) focal point in Java 3D. I think Renoir is
> using it to mean the point at which he expects zbuffer rendering to be

> further away might exhibit zbuffer artifacts).
Hope it helps,
Renoir
