Basic Structure of LG3D App
Frmae3D frame = new Frame3D();
Container3D container = new Container3D();
// Creation of a shape – set geometry,
// appearance, texture, animation, etc.
Component3D comp = new Component3D();
comp.addChild(shape);
// Initialize event handling and animation
// against this component
comp.addListener(anEventListener);
comp.addAnimation(anAnimation);
container.addChild(comp);
frame.addChild(container);
frame.changeVisibility(true);
frame.changeEnabled(true);
