I have a problem to set an animation. I have the following:
sage: L1 =
sphere((0,0,0),5)
sage: L2 = L1.rotateZ(pi/3)
sage: L1.save('one.png',aspect_ratio=[1,1,1],frame=False)
sage: L2.save('dos.png',aspect_ratio=[1,1,1],frame=False)
One of the images is much smaller than the other, this posses problems for
making an animation like:

For that animation I onstructed the frame and then put it inside a
transparent sphere containing the whole scene. But this is an ugly hack.
What is the propeer way to rotate an object without suffering "zooming"
effect? This is related to the more general question. Is there a way to
deal with the camera using tachyon viewer? For instance, it seems that for
implicit3d objects, the tachyon viewer has the camera hard-coded.
Thanks
