I am looking for information on the varieties of visibility graphs in terms
of the spatial overlap (also indicated by measures such as Control and
Clustering Coefficient) of isovists amongst the observers.
It is trivial to imagine the two extremes of isovist overlaps visibility
graphs viz. (i) the VG of a convex open space in which isovists of all
observers overlap and (ii) the VG of some non-convex open space in which
there is minimal overlap of isovists amongst the observers. The remaining
cases are naturally of partial overlaps.
I am particularly interested in the case of visbility graph that can be
regarded as located in the middle of the two extremes.
Thanks,
Sanjay.
