Detailed Description

An interface for the definition of light sources.

In addition to managing the attributes of the light source, as defined in the class LightSource, Light provides an abstract method render() which must be implemented in descendants to put the light source into the scene.

Constructor & Destructor Documentation

Light::Light	(	const VecMath::Vector< 4 > &	pos,
		const Color &	a,
		const Color &	d,
		const Color &	s
	)		[inline]

Construct a light directly from location and color values.

Parameters:

pos	The light source's location in homogenous coordinates
a	The light source's ambient color
d	The light source's diffuse color
s	The light source's color for specular reflections
