mesh.drectangle: Rectangle distance function

In geometry: Mesh Generation and Surface Tessellation

Rectangle distance function

Description

Signed distance from points p to boundary of rectangle to allow easy definition of regions in distmesh2d.

Usage

mesh.drectangle(p, x1 = -1/2, y1 = -1/2, x2 = 1/2, y2 = 1/2, ...)

Arguments

p	A matrix with 2 columns, each row representing a point in the plane.
x1	lower left corner of rectangle
y1	lower left corner of rectangle
x2	upper right corner of rectangle
y2	upper right corner of rectangle
...	additional arguments (not used)

Value

a vector of length nrow(p) containing the signed distances
