/*
A Light defines a source of light in the scene. Generally, two types
of information are of interest: The position of the light source
(geometry), and what elements of the scene are lit (semantics).
Using the position of the light in the graph for geometry allows
moving the Light just like any other node, by putting it below a
OSG::Transform Node and changing the transformation. This consistency
also simplifies attaching Lights to moving parts in the scene: just
put them below the same Transform and they will move with the object.
The semantic interpretation also makes sense, it lets you restrict the
influence area of the light to a subgraph of the scene. This can be
used for efficiency, as every active light increases the amount of
calculations necessary per vertex, even if the light doesn't influence
the vertex, because it is too far away. It can also be used to
overcome the restrictions on the number of lights. OpenSG currently
only allows 8 concurrently active lights.
It is also not difficult to imagine situations where both
interpretations are necessary at the same time. Take for example a car
driving through a night scene. You'd want to headlights to be fixed to
the car and move together with it. But at the same time they should
light the houses you're driving by, and not the mountains in the
distance.
Thus there should be a way to do both at the same time. OpenSG solves
this by splitting the two tasks to two Nodes. The Light's Node is for
the sematntic part, it defines which object are lit by the Light. FOr
the geometrc part the Light keeps a SFNodePtr to a different Node, the
so called beacon. The local coordinate system of the beacon provides
the reference coordinate system for the light's position.
Thus the typical setup of an OpenSG scenegraph starts with a set of
lights, which light the whole scene, followed by the actual geometry.
Tip: Using the beacon of the camera (see \ref PageSystemWindowCamera)
as the beacon of a light source creates a headlight.
Every light is closely related to OpenGL's light specification. It has
a diffuse, specular and ambient color. Additionally it can be switched
on and off using the on field.
