Here's how I move the viewplatform:
These are defined as Class Fields:
static TransformGroup VPTG; // ViewPlatform Transform Group
static Transform3D VPT3D; // ViewPlatform Transform Group Transform3D
In your main method or whatever helper method you have to create the scene,
you will usually see something like this:
scene = new BranchGroup();
// SimpleUniverse is a Convenience Utility class
SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
// This will move the ViewPlatform back a bit so the
// objects in the scene can be viewed.
// simpleU.getViewingPlatform().setNominalViewingTransform();
I commented out the last line because I want to implicitly set the viewer's
position.
You need to be sure that Viewplatform doesn't have more than one transform
since it is a
MultitransformGroup, so do this:
int num =
simpleU.getViewingPlatform().getMultiTransformGroup().getNumTransforms();
System.out.println("Number of transforms =" + num);
Provided that num = 1, then there is only one Transform and its index is 0
(array nomenclature)
So now do this:
VPTG = new TransformGroup();
VPTG =
simpleU.getViewingPlatform().getMultiTransformGroup().getTransformGroup(0);
// Notice the 0
VPT3D = new Transform3D();
// This will move the position to Z = 30, you may want to do rotations
as well, so use the appropriate methods
VPT3D.setTranslation(new Vector3f(0.0f, 0.0f, 30.0f));
VPTG.setTransform(VPT3D);
That's it. Works for me for the SimpleU.
