rtini_error: Compute RTIN Surface Approximation Error on a Height Map

In brodieG/rtini: Right Triangle Irregular Network Surface Approximation

Description

A vectorized adaptation of Vladimir Agafonkin's MARTINI implementation of the Evans etal. Right Triangulated Irregular Networks surface approximation algorithm. Accepts a broader set of input matrix dimensions than MARTINI.

Usage

rtini_error(map)

Arguments

map	numeric matrix with at least three rows and three columns, and with an odd number of each. It is expected that the input is finite and does not contain NAs.

Value

numeric matrix of the same dimension as map with the maximum of the rtin approximation error at each point and the equivalent approximation at the child points.
