glm::reflect
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 - ...
glm::distance
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).
