\title{Sphere distance function}
\usage{
mesh.dsphere(p, radius = 1, ...)
}
\arguments{
\item{p}{A matrix with 2 columns (3 in \code{mesh.dsphere}), each row
representing a point in the plane.}
\item{radius}{radius of sphere}
\item{...}{additional arguments (not used)}
}
\value{
A vector of length \code{nrow(p)} containing the signed
distances to the sphere
}
