\description{
  Arguments common to the 3d Trellis display functions \code{cloud} (and
  the as yet unimplemented wireframe)
}
\alias{trellis.3d.args}
\alias{trellis.3d.function}
\arguments{
  \item{formula}{ formula of the form \code{z ~ x * y | g_1 * g_2 * \dots}}
  \item{data}{ data frame in which variables are evaluated.}
  \item{aspect}{ vector of length 2, giving the relative aspects of the
    y-size/x-size and z-size/x-size of the enclosing rectangle.}
  \item{scales}{describes scales. not used yet }
  \item{zlab}{z label}
  \item{zlim}{z limits}
  \item{distance}{ between 0 and 1, controls amount of perspective. No
    connection with the physical concept of distance in this
    implementation (not clear what S+ does). individual values don't give
    the same results as S-Plus, but all instances should be achievable.}
  \item{par.box}{graphical parameters for box, not implemented yet}
  \item{perspective}{logical, whether to plot a perspective view}
  \item{R.mat}{initial rotation matrix (homogeneous coordinates). Not
    implemented. }
  \item{screen}{A list determining the rotations to applied to the data
    before being plotted. The initial position starts with the view
    somewhere in the positive z-axis, and the x and y axes in the usual
    position. Each component of the list should be named one of \code{x,
      y, z}, with their values indicating the amount of rotation about
    that axis in degrees.   }
  \item{zoom}{factor by which to scale the picture.}
}
\details{
  These functions also take other arguments, as described in the
  documentation for \code{trellis.args}.
