Well, you're close. Actually, dolly moves are still used today. Zooming a
lens has a different effect. The focal length of the lens changes and
therefor the depth of field and a multitude of other factors change. A
dolly keeps the same focal length but brings the camera closer or farther
away from the subject. Pick up any photography book at the library
for a more detailed explaination of focal length.
Sometimes even a combination of these techniques are used, especially to
show terror, as in Poltergiest for example. The actor seems to remain the
same size in the frame while the background appears to fall away. This is
achieved by dollying in while zooming out. I don't know if this is
possible in Lightwave, but it should be.
What you are describing I think would be a crane move in the real world.
Dollying in or out is simple along the x or z axis. If moving diagonally
is what you are talking about, I agree, that's more difficult since you
have two or three axis of movement.
I think this is cleared up in my mind. Thanks,
