The VTK User Guide discusses animation.  The standard approach is to
define curves that you want to move your camera along and then step
over this curve to produce your animation.  You can define a series of
points and then use spline interpolation to generate smooth
trajectories over these curves.

See the example Examples/Rendering/Tcl/keyBottle.tcl
