Detailed Description

Zooms camera with vertical mouse movement.

vtkPVTrackballZoom allows the user to interactively manipulate the camera, the viewpoint of the scene. Moving the mouse down zooms in. Up zooms out.

When zooming in Perpective projection, this manipulator by default, dollys (rather than zooms) i.e. moves the camera further (or farther) in the view direction. This is default behavior. You can change that to use zoom instead i.e. change view angle on camera, by setting UseDollyForPerspectiveProjection to off.
