One white global light illuminates the scene by default. This can be changed through a light manager object and a certain number of lights (limited by OpenGL). The first step is to add the object called LightManager, preferably at the top of the scene file.
After that, we can add 3 different kinds of lights :
a positional light (parameters : color, position) ;
a directional light (parameters : color, direction) ;
a spotlight (parameters : color, position, direction, cut off, exponent, attenuation)
