\title{Triangle mask helpers for recursive gasket families}
\usage{
mask.triangle.classic()

mask.triangle.bridge(missing = c("top", "left", "right"))
}
\arguments{
\item{missing}{Which outer corner is omitted in
\code{mask.triangle.bridge()}.}
}
\value{
A named logical vector of length 4.
}
\description{
Convenience constructors for the four-slot triangle masks used by
\code{\link{edges.recursive.triangle.mask}()} and
\code{\link{recursive.triangle.mask.surface.graph}()}. The slots correspond
to the three corner subtriangles and the central inverted subtriangle created
by one barycentric refinement of an equilateral triangle.
}
\details{
The returned mask entries are ordered and named as \code{left},
\code{right}, \code{top}, and \code{center}.
