Objet : Re: [JAVA3D] Multiple views on screen
Below is one way I put 4 views in one panel. The code is for a
constructor of a class which extends the JPanel. Basically, to do a
multipleview system you have to get away from using the
SimpleUniverse... you need to use a VirtualUniverse instead and then
define all of the steps yourself. I have comments for each step so that
should not be too hard to follow....this will generate a multiwindow
system with one (main) window on the left and 3 small windows on the
right side:
+-----+--+
| +--+ I've attached a picture of what my application looks
like
with those 4 windows.
| +--+
+-----+--+
One thing to note is that you'll have to create other TransformGroup (or
something else) to add to the viewplatforms
TransformGroup objgrp2 = new TransformGroup();
objgrp2.addChild(viewplatform2);
and then I added these TransformGroups to my objects
myObjectImLookingAt.addChild(objgrp2);
I hope that was clear/understandable...I did this a few months back and
I'm not sure if remember everything....plus I'm still new to this Java3D
so it's hard for me to explain it all...

Subject: [JAVA3D] Multiple views on screen
My question is really simple. I have a scene graph describing a 3d scene
and I want to display it in multiple canvas each having is own point of
view. So if my scene is representing a car, I want one canvas displaying
it from the front, and one where the camera is placed above or behind
the same car. I want to do this using the same scenegraph. How could i
do such a thing ? Cordialement, Jonathan Smolarski. Mail :
