Average of two graphs

(Sent this mail from another email adress, dont know whether it failed
or worked, sorry)

(I'm proud to, for the first time, query the mailing list with a
non-technical issue that I have :->)

Is there a ready-to-use function to get the "Average of two graphs" I think of that as the following:

The average graph c of two graphes a and b is given by a parametrisation
(c1,c2)(t) 0 < t < 1 where (c1,c2)=( (a1,a2)(t) + (b1,b2)(t) )/2 and
a(t), b(t) the parametrisations of a and b respectively.

Well, I just sort of made that up, but does something like that exist? It would be useful after all! Received on Wed Mar 31 2010 - 01:06:50 CEST
