Hi,

First of all, I would like to thank you for your answers.
But, the problems was still here.

I know about the alpha and I tried lots of time just like you said me with
whatever alpha value. Event if I put a maximum value of alpha (which must give
me one edge : the qhull whatever entries points) I had absolutely no Edge. I
tried also with the same value and same points in the Alpha Shape 2 demo
provide by CGAL... but problem was still here.

Concerning my Delaunay, He is just like he have to be.

The only thing I notice Is that after the method "make_alpha_shape()" my alpha
value was reset to 0 even if it was his first initialization... So I re-set my
alpha value after  my shape making and It`s now working ! 

Sorry for the disturb, but I don`t remember have read that the alpha value 
have
to be set AFTER the alpha making (But you may notice that my English is very
approximative).

Thank you very much for your help.

Just If I could have an advice, I now want to detect all of the point inside 
my
polygons (alpha shape edges) even if they not participate to the construction
of these ones. Could SomeOne have an idea how I can do that easily or must 
have
I to do that by myself ?

Thank you very much !
