GLM_FUNC_DECL genType faceforward(genType const &N, genType const &I, genType const &Nref)
If dot(Nref, I) < 0.0, return N, otherwise, return -N.
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.

Returns the cross product of x and y.
GLM_FUNC_DECL genType normalize(genType const &x)
Returns a vector in the same direction as x but with length of 1.
GLM_FUNC_DECL genType::value_type length(genType const &x)
Returns the length of x, i.e., sqrt(x * x).
