Appends the specified child node to this group node's list of children.

Usage

From source file:AvatarTest.java

public TransformGroup addBehaviors(Group bgRoot) {
    // Create the transform group node and initialize it to the
    // identity. Enable the TRANSFORM_WRITE capability so that
    // our behavior code can modify it at runtime. Add it to the
    // root of the subgraph.
    TransformGroup objTrans = new TransformGroup();
    objTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);

    Transform3D zAxis = new Transform3D();
    zAxis.rotY(Math.toRadians(90.0));

    Alpha zoomAlpha = new Alpha(-1, Alpha.INCREASING_ENABLE, 0, 0, 20000, 0, 0, 0, 0, 0);
