Can someone please point me to a simple example of how to set up mouse
navigation in a virtual world? I've tried everything I can think of and
am still missing something.
My program [snips below] compiles and runs, but the mouse doesn't do
anything.
(I'll be cutting the program down to it's simplest form to work this out
and will post it in its entirety if needed)
//---------In the root program--------------------------------------
public class NewWorld001 extends Applet implements ActionListener
{
TransformGroup moveView = new TransformGroup();
//---------Here's what's in the objectGraph BranchGroup:----------
// Create the bounding leaf node
BoundingSphere bounds = new BoundingSphere(new Point3d(0.0,0.0,0.0),
100.0);
BoundingLeaf boundingLeaf = new BoundingLeaf(bounds);
objScale.addChild(boundingLeaf);
// Create the drag behavior node
MouseRotate behavior = new MouseRotate();
behavior.setTransformGroup(moveView);
moveView.addChild(behavior);
behavior.setSchedulingBounds(bounds);
// Create the zoom behavior node
MouseZoom behavior2 = new MouseZoom();
behavior2.setTransformGroup(moveView);
moveView.addChild(behavior2);
behavior2.setSchedulingBounds(bounds);
// Create the translate behavior node
MouseTranslate behavior3 = new MouseTranslate();
behavior3.setTransformGroup(moveView);
moveView.addChild(behavior3);
behavior3.setSchedulingBounds(bounds);
//----------Under Public void
init()--------------------------------------
u.getViewingPlatform().setNominalViewingTransform();
u.addBranchGraph(scene);
TransformGroup t = u.getViewingPlatform().getViewPlatformTransform();
Transform3D trans = new Transform3D();
t.getTransform(trans);
Transform3D holder2 = new Transform3D();
moveView.getTransform(holder2);
t.setTransform(holder2);
