Triangulate an RTriangle pslg with the CDT backend

Source: R/cdt.R
cdt_pslg.Rd

Convenience for input in the shape of RTriangle::pslg(): a list with P, a two-column matrix of vertex coordinates, and S, a two-column matrix of 1-based segment vertex indices.

Usage

cdt_pslg(p, ...)

Arguments

p

a pslg (list with P and S)

...

passed to cdt_triangulate()

Value

the list returned by cdt_triangulate()

Examples

p <- list(P = cbind(c(0, 2, 2, 1, 0), c(0, 0, 2, 1, 2)),
          S = cbind(1:5, c(2:5, 1)))
r <- cdt_pslg(p, max_area = 0.05)
nrow(r$T)
#> [1] 102
plot(r$P, asp = 1, pch = ".")
polygon(r$P[t(cbind(r$T, NA)), ])
