Constructor & Destructor Documentation

VRS::SpotLight::SpotLight	(	const Vector &	pos = Vector(0, 0, 0),
		const Vector &	dir = Vector(1, 0, 0),
		const Color &	col = Color::white,
		double	spotAngle = 45,
		double	spotExponent = 10,
		double	intensity = 0.5,
		double	ambientIntensity = 0.05,
		double	const_attenuation = 1.0,
		double	linear_attenuation = 1.0,
		double	quadratic_attenuation = 0.0
	)

A spot-light is a directed-light. It is emitted from a point and the rays go towards the directrion. No Rays outside of `spotAngle' are cast. The `spotExponent' controlls the fall-off. Higher values produce smaller spots.
