Functions
template<typename valType >
detail::tvec3< valType >	cross (detail::tvec3< valType > const &x, detail::tvec3< valType > const &y)
	Returns the cross product of x and y.
template<typename genType >
genType::value_type	distance (genType const &p0, genType const &p1)
	Returns the distance betwwen p0 and p1, i.e., length(p0 - p1).
template<typename genType >
genType::value_type	dot (genType const &x, genType const &y)
	Returns the dot product of x and y, i.e., result = x * y.
template<typename genType >
genType	faceforward (genType const &N, genType const &I, genType const &Nref)
	If dot(Nref, I) < 0.0, return N, otherwise, return -N.
template<typename genType >
genType::value_type	length (genType const &x)
	Returns the length of x, i.e., sqrt(x * x).
template<typename genType >
genType	normalize (genType const &x)
	Returns a vector in the same direction as x but with length of 1.
template<typename genType >
genType	reflect (genType const &I, genType const &N)
	For the incident vector I and surface orientation N, returns the reflection direction : result = I - 2.0 * dot(N, I) * N.
template<typename genType >
genType	refract (genType const &I, genType const &N, typename genType::value_type const &eta)
	For the incident vector I and surface normal N, and the ratio of indices of refraction eta, return the refraction vector.
