Hello all,

I have sets of points in (x,y,z) that represent polyhedron vertices (actually tree crowns). I have used convhulln to estimate volumes (the shapes are not necessarily convex, but good enough for now). Now I would like to extract various dimensions of these shapes - horizontal width (max, mean), vertical depth (max, mean), and other metrics.

Are there any packages/tools in R that might help me do this? A look around didn't come up with anything.

Thanks in advance,
Allie
