Functions
template<typename T , qualifier Q>
GLM_FUNC_DECL vec< 3, T, Q >	cross (vec< 3, T, Q > const &x, vec< 3, T, Q > const &y)
	Returns the cross product of x and y. More...
template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL T	distance (vec< L, T, Q > const &p0, vec< L, T, Q > const &p1)
	Returns the distance betwwen p0 and p1, i.e., length(p0 - p1). More...
template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL T	dot (vec< L, T, Q > const &x, vec< L, T, Q > const &y)
	Returns the dot product of x and y, i.e., result = x * y. More...
template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL vec< L, T, Q >	faceforward (vec< L, T, Q > const &N, vec< L, T, Q > const &I, vec< L, T, Q > const &Nref)
	If dot(Nref, I) < 0.0, return N, otherwise, return -N. More...
template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL T	length (vec< L, T, Q > const &x)

template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL vec< L, T, Q >	normalize (vec< L, T, Q > const &x)
	Returns a vector in the same direction as x but with length of 1. More...
template<length_t L, typename T , qualifier Q>
GLM_FUNC_DECL vec< L, T, Q >	reflect (vec< L, T, Q > const &I, vec< L, T, Q > const &N)
	For the incident vector I and surface orientation N, returns the reflection direction : result = I - 2.0 * dot(N, I) * N. More...
