\usage{
csg_cylinder(
  start = c(0, 0, 0),
  end = c(0, 1, 0),
  radius = 1,
  corner_radius = 0
)
}
\arguments{
\item{start}{Default `c(0, 0, 0)`. Start point of the cylinder, specifing `x`, `y`, `z`.}

\item{end}{Default `c(0, 1, 0)`. End point of the cylinder, specifing `x`, `y`, `z`.}

\item{radius}{Default `1`. Cylinder radius.}

\item{corner_radius}{Default `0`. Radius if rounded cylinder.}
}
\value{
List describing the cylinder in the scene.
