glm::reflect
GLM_FUNC_DECL vec< L, T, P > reflect(vec< L, T, P > const &I, vec< L, T, P > const &N)
For the incident vector I and surface orientation N, returns the reflection direction : result = I - ...
glm::normalize
GLM_FUNC_DECL vec< L, T, P > normalize(vec< L, T, P > const &x)
Returns a vector in the same direction as x but with length of 1.
glm::dot
GLM_FUNC_DECL T dot(vec< L, T, P > const &x, vec< L, T, P > const &y)
Returns the dot product of x and y, i.e., result = x * y.
