CGAL users discussion list

Hello everybody,

A a user of CGAL, I wish to bring up a point(_3) which I think is important 
to users of geometric software to which they don't want or need to change to 
code itself. 

I find it bothersome that I can't have more control over the process of the 
geometric algorithms. For instance, if I want to compute the straight 
skeleton, and in which to apply some function in every event (like matching 
between the vertices participating or something), I cannot do this online, 
and have to settle for post-processing, or some sophisticated workaround 
which might be available, but I don't know about..

Is there a way (or a possibility) to establish a way in CGAL to allow users 
to pass functions as arguments to the algorithm, which it will apply in 
specified occasions? (another example, the finding of an intersection in a 
symmetric difference, so I wouldn't have as an output the same vertex in two 
different polygon, and have to post-establish that this is the same vertex).

I think this functionality is very important, and I would like to hear you 
opinions about it.

Thanks,
