Hi Roni
Could it be, that the zooming depends on the eye-distance.
eye-distance * zoom-factor
If you come closer the zoom-step will decrease...
I think this is the concept which is implemented in OpenSceneGraph.

Hello
In my application I'm using a trackball manipulator and a large terrain.
When I'm zooming in to the terrain, many times (not always) the
trackball starts moving slower and slower until the camera can't move
any more. I can move backwards but very slowly until I can accelerate
again and I'm back to normal speed.
Anyone had this problem?
(I'm using osg 2.4 but also happened in 2.2)
