template<typename T , precision P>
GLM_FUNC_DECL tvec3< T, P >	cross (tvec3< T, P > const &x, tvec3< T, P > const &y)
	Returns the cross product of x and y. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL T	distance (vecType< T, P > const &p0, vecType< T, P > const &p1)
	Returns the distance betwwen p0 and p1, i.e., length(p0 - p1). More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL T	dot (vecType< T, P > const &x, vecType< T, P > const &y)
	Returns the dot product of x and y, i.e., result = x * y. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< T, P >	faceforward (vecType< T, P > const &N, vecType< T, P > const &I, vecType< T, P > const &Nref)

template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< T, P >	normalize (vecType< T, P > const &x)
	Returns a vector in the same direction as x but with length of 1. More...
template<typename genType >
GLM_FUNC_DECL 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. More...
