Detailed Description

Utility to cast Light into a Opengl scene.

This class must be used in a scene with one LightManager object. This abstract class defines lights (i.e basically id and color) The inherited lights are:

• Directional light (direction);
• Positional light (position);
• Spot light (position, direction, cutoff...).
