Lights

This diagram shows a light and its three light DAG nodes, grouped under a common group node. To create this structure, instantiate and create one of the several different light types. The three light nodes (the position, look at, and up DAG nodes) are created. The three light DAG nodes are grouped under a common group node. All of the different light types make use of the position DAG node; however, only the AlSpotLight makes use of the look at and up nodes.
