mesh.dsphere: Sphere distance function

In geometry: Mesh Generation and Surface Tessellation

Sphere distance function

Description

Signed distance from points p to boundary of sphere to allow easy definition of regions in distmeshnd.

Usage

mesh.dsphere(p, radius = 1, ...)

Arguments

p	A matrix with 2 columns (3 in mesh.dsphere), each row representing a point in the plane.
radius	radius of sphere
...	additional arguments (not used)

Value

A vector of length nrow(p) containing the signed distances to the sphere
