\usage{
disk(x = 0, y = 0, z = 0, radius = 1, inner_radius = 0,
  material = lambertian(), angle = c(0, 0, 0), order_rotation = c(1,
  2, 3), velocity = c(0, 0, 0), flipped = FALSE, scale = c(1, 1, 1))
}
\arguments{
\item{x}{Default `0`. x-coordinate of the center of the disk}

\item{y}{Default `0`. y-coordinate of the center of the disk}

\item{z}{Default `0`. z-coordinate of the center of the disk}

\item{radius}{Default `1`. Radius of the disk.}

\item{inner_radius}{Default `0`. Inner radius of the disk.}

\item{material}{Default  \code{\link{lambertian}}.The material, called from one of the material 
functions \code{\link{lambertian}}, \code{\link{metal}}, or \code{\link{dielectric}}.}

\item{angle}{Default `c(0, 0, 0)`. Angle of rotation around the x, y, and z axes, applied in the order specified in `order_rotation`.}

\item{order_rotation}{Default `c(1, 2, 3)`. The order to apply the rotations, referring to "x", "y", and "z".}

\item{velocity}{Default `c(0, 0, 0)`. Velocity of the disk.}

\item{flipped}{Default `FALSE`. Whether to flip the normals.}

\item{scale}{Default `c(1,1,1)`. Scale transformation in the x, y, and z directions.}
