Functions
Color	operator * (float s, const Color &c)
	Component-wise multiplication with scalar (mixed-mode).
std::ostream &	operator<< (std::ostream &os, const Color &c)
	Write color values to an output stream in text format.
static float	uniform ()
	Returns a uniform random number in the range [0,1).
static std::string	int2str (int i)
	Helper function for converting an int to a string.
static void	swap (float &a, float &b)
	Swaps two floats.
template<class T>
T	max (T a, T b)
	Returns the maximum of the two elements.
template<class T>
T	min (T a, T b)
	Returns the minimum of the two elements.
std::ostream &	operator<< (std::ostream &os, const Matrix &A)
	Write matrix elements to an output stream.
std::ostream &	operator<< (std::ostream &os, const Vector &A)
	Write elements to an output stream.
std::ostream &	operator<< (std::ostream &os, const Point &A)
	Write elements to an output stream.
Variables
static float	INF = std::numeric_limits<float>::infinity()
	Define positive infinity for floats.
static const float	epsilon = 1e-6
	Small value.
static Diffuse	DEFAULT_MATERIAL = Diffuse(Color(0.7f,0.7f,0.7f))
	Default material is a gray diffuse material.
static const char	EXR_OUTPUT_COMMENT [] = "ASR Raytracer"
	This string is stored as a comment in exr files written by this class.
static const float	EMPTY_BONUS = 0.1f
	Nodes in the tree which are completely empty are assigned a bonus between 0 and 1 during tree construction as they will speed up traversal by cutting of empty portions of the scene.
static const float	INTERSECTION_COST = 80.0f
	The cost of performing a ray/object intersection.
static const float	TRAVERSAL_COST = 1.0f
	The cost of traversing into a node in the tree.
const float	overlap = 1e-3
	Triangle overlap distance to avoid problems at edges.
