Try using the option SphericalRegion->True.  Also, if you want to do any
specialized rotations, you could make your job a bit easier by looking at the
SpinShow command in the Graphics`Animation` package.

Hi.  I'm trying to produce an animation of a 3-D object to simulate
the smooth rotation of the object about the vertical axis.  I came up
with

  Table[Show[3DObject, Boxed -> False,
  ViewPoint->{ 2 Cos[n 2 Pi/60], 2 Sin[n 2 Pi/60],2 }],
  {n, 0, 60}];

This *almost* worked.  The only problem is that Mathematica doesn't
keep the size of 3DObject constant (wrt to the rest of the window)
from one frame to the next, so the image zooms in and out as it
rotates (a semi-cool effect, in face, but not exactly what I had in
mind).  How can I get Mathematica to keep the image size constant wrt
the window from one frame to the next?

Thanks in advance,

Z.
