+/** Example 020 Managed Lights
+
+Written by Colin MacDonald. This tutorial explains the use of the Light Manager
+of Irrlicht. It enables the use of more dynamic light sources than the actual
+hardware supports. Further applications of the Light Manager, such as per scene
+node callbacks, are left out for simplicity of the example.
+*/

+#endif // MSC_VER
+
+/*
+ Normally, you are limited to 8 dynamic lights per scene: this is a hardware limit. If you
+ want to use more dynamic lights in your scene, then you can register an optional light
+ manager that allows you to to turn lights on and off at specific point during rendering.
+ You are still limited to 8 lights, but the limit is per scene node.
+
+ This is completely optional: if you do not register a light manager, then a default
+ distance-based scheme will be used to prioritise hardware lights based on their distance
+ from the active camera.
+
+ NO_MANAGEMENT disables the light manager and shows Irrlicht's default light behaviour.
+ The 8 lights nearest to the camera will be turned on, and other lights will be turned off.
+ In this example, this produces a funky looking but incoherent light display.
+
+ LIGHTS_NEAREST_NODE shows an implementation that turns on a limited number of lights
+ per mesh scene node. If finds the 3 lights that are nearest to the node being rendered,
+ and turns them on, turning all other lights off. This works, but as it operates on every
+ light for every node, it does not scale well with many lights. The flickering you can see
+ in this demo is due to the lights swapping their relative positions from the cubes
+ (a deliberate demonstration of the limitations of this technique).
+
+ LIGHTS_IN_ZONE shows a technique for turning on lights based on a 'zone'. Each empty scene
+ node is considered to be the parent of a zone. When nodes are rendered, they turn off all
+ lights, then find their parent 'zone' and turn on all lights that are inside that zone, i.e.
+ are descendents of it in the scene graph. This produces true 'local' lighting for each cube
+ in this example. You could use a similar technique to locally light all meshes in (e.g.)
+ a room, without the lights spilling out to other rooms.
+
+ This light manager is also an event receiver; this is purely for simplicity in this example,
+ it's neither necessary nor recommended for a real application.
