Zooming in 3D - Macromedia Director 3D

How to zooming in 3D? I have different models in 3D world and i moves around these models.Now i want a create zooming on to a model , when the user clicks on that model in that direction? I tried by identifying a location for some models , but in this approach camera always goes to that same location. How to create zooming in this case i.e, zooming in all the directions? any ideas?...

    You have to create the 2nd camera and to "play" with these instructions:

    pointAt (camera to model)
    translate (camera)
    FOV (camera)

    thanx necromanthus for your suggestion,
    but i already followed the same technique,it is giving abrupt zooming on to
    the model. i want smooth zooming like when user selected a model the camera has
    to move smoothly from current position to the model.

    To get a smooth camera movement, create an invisible box (visibility = #none).
    This box is gonna be controlled (keyboard & mouse) instead of the camera.
    Now all you have to do is to use the interpolateTo command.

    necromanthus, you've inspired me to build such thing.
    here's the [url]http://bgsmediastuff.tripod.com/public/interbmV2.htm[/url].

    use the arrow keys to move the camera.

    as you said, i used the interpolateTo method on the camera, which follows a
    box transform.
