It is possible using the nef polyhedron library which supports the boolean operators used for CSG, although it can be slow compared to dedicated visual hull techniques due to use of exact arithmetic. I tested visual hull computation with CGAL using the nef_3 example application (which can be told what to do from the command line), by giving it .off files of truncated viewing cone polyhedrons, and let it generate the intersection. It was something I did last year while testing EPVH, the polyhedral visual hull library I developed during my thesis.

Hi.
Could I easily implement CSG operations such as
intersection, subtraction, etc with CGAL?
Actually, I'd like to implement a Shape from Silhouette
algorithm to create a visual hull from silhouette images.
