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 every point that
is inside some rectangular 3D area in this points cloud.

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
