Hello.

First: you have replied to a previous email, changing the email subject. 
But many email clients will group your email with previous ones - it's 
better to start a new thread.

On to your question: there has been a recent exchange on how to find 
intersections of geometrical objects (rays, segments) with bounding 
boxes, check out the archive. But for this particular case:

> I have a collection of points P in 3D space, and I want to identify

Do you really need CGAL? I mean, just look at the coordinates of the 
points, and check whether they are inside the box (by "rectangular 3D 
area" you mean "box", right?)

Best,

Daniel
