Dear all, again :)

I have a number of points, with each having certain properties (like 
temperature, etc..).

I can add an index to my alpha shape as described by 
https://lists-sop.inria.fr/sympa/arc/cgal-discuss/2008-02/msg00157.html, but 
only after the alpha shape has been created. Therefore I kind of loose the 
information connected to each point. I need to recalculate the alpha shape 
several times in the changing arrangement of points.

Is it possible to construct the vertices in the alpha shape already with the 
index they have in my simulation?

Thank you very much for your help!
