rfi | R Documentation |
Compute the relief index of a 3d triangle mesh.
rfi(mesh, method = "Ungar", hull = "concave")
mesh |
object of class mesh3d |
method |
a character string indicating which method is to be used for the computation of relief index |
hull |
the method used to compute the hull of the 2d projection, either 'convex' or 'concave'.
The default method is 'convex'. See |
As of version 1.42.2, the concave hull fails intermittently on Mac systems, so the function defaults to convex hulls (on other systems, it defaults to concave hulls).
A single relief index value.
