Certainly, there are a few demos around that use pre-calculated tables of
sine values but most them them [even the ones that aren't interactive]
are still doing the 3D calculations in real-time.  Most of the
vector ball routines are all pre-generated coordinates, however.  
I've seen numerous demos [including the Substance demo] that allow you
to actually control the movement of the objects.
