Usage

From source file:NodesTest.java

protected BranchGroup createSceneBranchGroup() {
    BranchGroup objRoot = super.createSceneBranchGroup();

    double labelScale = 20;

    // create the top level Switch Node
    // we will use the Switch Node to switch the
    // other Nodes on and off.
    // 1: Switch/* w w  w .jav a 2s.  co  m*/
    Switch switchGroup = new Switch();
    switchGroup.setCapability(Switch.ALLOW_SWITCH_WRITE);
    switchGroup.addChild(createLabel("1. Switch Label", labelScale));

    // 2: BranchGroup
    BranchGroup branchGroup = new BranchGroup();
    branchGroup.addChild(createLabel("2. BranchGroup", labelScale));
    switchGroup.addChild(branchGroup);

    // 3: OrderedGroup,
    OrderedGroup orderedGroup = new OrderedGroup();
    orderedGroup.addChild(createLabel("3. OrderedGroup", labelScale));
    orderedGroup.addChild(createLabel("Child 1", labelScale));
    orderedGroup.addChild(createLabel("Child 2", labelScale));
    switchGroup.addChild(orderedGroup);

    // 4: SharedGroup,
    SharedGroup sharedGroup1 = new SharedGroup();

    BranchGroup primitiveGroup = new BranchGroup();
    primitiveGroup.addChild(createLabel("5. Primitive", labelScale));

    transformGroup.addChild(new ColorCube(2));
    transformGroup.addChild(createLabel("6. TransformGroup", labelScale));
    switchGroup.addChild(transformGroup);

    // 7: add another copy of the shared group

    // cycle through the child nodes in the Switch Node

    SwitchValueInterpolator switchInterpolator = new SwitchValueInterpolator(switchAlpha, switchGroup);
    switchInterpolator.setSchedulingBounds(createApplicationBounds());
    switchInterpolator.setEnable(true);

    // WARNING: do not add the SwitchValueInterpolator to the Switch Node!
    objRoot.addChild(switchInterpolator);

    // finally add the Switch Node
