The trackball slows as you move into the origin as the rate of
movement in is always a percentage of distance from the center to the
eye point. This is just the way it works, it's not some that can be
"fixed" as it's doing exactly what it's meant to do.
Now if you want some custom manipulator that kinda behaves like the
TrackballManipulator then you'll need to subclass or just write your
own from scratch. One hack you could implement is the pushing
forward of the center as you get near to it, rather than just keep
reducing the distance between the eye and the center.

when I use the TrackballManipulator to view my model I find that the
camera velocity slows to zero if I try to approach a certain point,
which I believe is the origin.
Do you know why this occurs and how it can be prevented?
