Public Member Functions
	PointLight (Vector3D position, ColorRGBA intensity)
	Inititalize light source.
void	changeIllumination (float fac)
	Adds a constant factor to the intensity of the light.
bool	Illuminate (Ray &ray, ColorRGBA &intensity, unsigned int index=0)
	Illuminate a ray by this light source. The illumination is done by computing the attenuation factor which is based on the distance to the surface point and the light source.
Private Attributes
Vector3D	position
	The position of the light.
ColorRGBA	intensity
	The emission of the lightsource.
