Public Member Functions
	Phong (const Color &d, const Color &s, float e, float r=0.0f, float t=0.0f, float n=1.0f)
	Constructs a Phong material with diffuse color d, specular color s, and exponent (shininess) e, and (optionally) reflectivity r and transparency t, and index of refraction n.
virtual	~Phong ()
	Destructor.
Color	getBRDF (const Intersection &is, const Vector &L)
	Returns the BRDF at the intersection is for the light direction L.
virtual float	getReflectivity (const Intersection &is) const
	Returns the reflectivity of the material in the range [0,1] at the intersection, where 0 means not reflective at all, and 1 gives a perfect mirror.
virtual void	setReflectivity (float r)
	Sets the reflectivity of the material.
virtual float	getTransparency (const Intersection &is) const
	Returns the transparency of the material in the range [0,1] at the intersection, where 0 is fully opaque, and 1 is fully transparent.
virtual void	setTransparency (float t)
	Sets the transparency of the material.
virtual float	getIndexOfRefraction () const
	Returns the index of refraction for the material.
virtual void	setIndexOfRefraction (float n)
	Sets the index of refraction. Empty space is 1, denser materials higher.
Protected Attributes
Color	mDiffColor
	The diffuse color.
Color	mSpecColor
	The specular color.
float	mExponent
	The Phong exponent (shininess).
float	mReflectivity
	The reflectivity of the material.
float	mTransparency
	The transparency of the material.
float	mRefractionIndex
	Index of refraction for the material.

Detailed Description

Class representing a simple phong material.

The BRDF is computed at an intersection point by evaluating Phong's shading model. The material has a diffuse and a specular component, which can have different colors. The phong exponent specifies the amount of shininess, ranging from perfectly diffuse to highly specular.
