Hey guys, Thanks so much for the help, turns out I figured it out about an
hour after sending the question. I basically just started looking for
methods and found the getAWTEvent(). I didn't retract the question because I
wanted to see if I was doing it correctly, meaning in a manner that would
use up memory or processing power. Thanks again for the help. I have a new
question regarding this though. Part of the reason I wanted to get the key
events was to be able to move the viewport around a scene. I'm getting an
error from my code and I don't understand why its happening.
The Exception is:
xception in thread "main" javax.media.j3d.RestrictedAccessException: Cannot
mod
fy capability bits on a live or compiled object
at
javax.media.j3d.SceneGraphObject.setCapability(SceneGraphObject.java:
01)
at UniversePanel.createSceneGraph(UniversePanel.java:45)
at UniversePanel.<init>(UniversePanel.java:27)
at J3DViewer.<init>(J3DViewer.java:12)
at J3DViewer.main(J3DViewer.java:51)
and the code where it occurs happens here. My question is, it is not
possible to move the view port using this method? if not, how can I go about
doing it??
private void createSceneGraph(SimpleUniverse su) {
BranchGroup objRoot = new BranchGroup();
vpTrans = su.getViewingPlatform().getViewPlatformTransform();
objRotate = new TransformGroup();
initial = new Transform3D();
eye = new Point3d(eyePts);
center = new Point3d(0, 0, 0);
up = new Vector3d(0, 1, 0);
zb = new ZoomBehavior(vpTrans);
rb = new RotateBehavior(objRotate);
vpTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
objRotate.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
objRoot.addChild(objRotate);
objRotate.addChild(new ColorCube(0.4));
zb.setSchedulingBounds(new BoundingSphere());
rb.setSchedulingBounds(new BoundingSphere());
objRoot.addChild(rb);
objRoot.addChild(zb);
initial.lookAt(eye, center, up);
initial.invert();
vpTrans.setTransform(initial);
objRoot.compile();
universe.addBranchGraph(objRoot);
}
Thanks again for the other help and thanks for any help with this matter.
Eric
