Public Member Functions
	Checker (Material *m1, Material *m2, int nu, int nv)
	Constructs a checkerboard material consisting of two sub-materials, one for odd and one for even squares.
virtual	~Checker ()
	Destructor.
Color	getBRDF (const Intersection &is, const Vector &L)
	Returns the BRDF at the intersection is for the light direction L.
float	getReflectivity (const Intersection &is) const
	Returns the reflectivity of the material in the range [0,1], where 0 means not reflective at all, and 1 gives a perfect mirror.
float	getTransparency (const Intersection &is) const
	Returns the transparency of the material in the range [0,1], where 0 is fully opaque, and 1 is fully transparent.
void	setReflectivity (float r)
	Sets the reflectivity of the material by setting the reflectivity of the two sub-materials.
void	setTransparency (float t)

Detailed Description

Class representing a simple checkerboard material.

This material takes pointers to two other materials in the constructor, and alternately chooses between them based on the texture coordinates. Hence, it gives a square pattern, where the odd/even squares are made of different materials. It can be used for creating checker boards. The reflectivity and transparency at an intersection point is determined by the material that is used for the square the ray hit. However, only one index of refraction is used for the entire material, and must be set on the Checker material instead of its sub-materials.
