Hi,

Is there a way I can check if the vector is normalized or not ? I think this is a kernel dependent function since there are multiple data types that can be used, so I was wondering if something like that is available ?

Related to this, is there a function / functor which I can call to normalize the given vector ?

Also, I read this about directions: " They can be
viewed as unit vectors, although there is no normalization internally,
since this is error prone". After reading this, I am not sure how/when can I use Direction. 

I have a projecting operation that I want to perform, something like this:

Point_3& newPoint = midPt + (direction * dist_Proj);

where midPt is a Point3, 
direction = vector  (I want this to be a normalized vector)
dist_proj = double value

Can anyone please recommend me what would be a good way to do this in CGAL ?

Thank you
