my java3d project problem!!help

I’m doing a project that use java3D(or xith3D) to load 3D model to current scene.It suppose to user can point a place by mouse,the camera would follow and zoom that place.now I can load a quake3 scene to my app.BUT,how can I do the other job??
another question:How to convert a 3ds MAX file to a .bsp file??
(I use bsp to manage my 3D-graph),Thanks very much!!!

i m also facing the same problem…i also want tat when the user clicks on the screen, then is should zoom from that place ,not from the center. if u find any solution ,then plzzz let me know also…i will also do the same if i got any solution…

The start of your problem is picking- have a look through the pickray and picking tools part of the javadocs.

From there it should be easy enough to create a behaviour to move your viewplatform to the right place.
