David:

You're right. I'm just bothered by a problem:
how to do the fly through in a 3D image data set?
Do you have time to help me?

RSI's IDL demo gave us a 'fly through' demo,
in fact, that is not fly through, it's fly over.
It use a 2D surface array to fly over it.
What I want to do is a 3D array, user can display
iso-surface or even volume rendering, then flying
through by mouse-guiding or a predefined path.
I think the basic thing is the same, to use
3d graphics model, apply the translate, rotate, and
zoom ... methods... only thing I worry is that
the process could be very slow.

Has anyone already written similar codes? If you
dont want to share the code, please just tell me
whether it's tolerable in speed.

Thanks David, Thanks everyone!
