\name{rgl.postscript}
\alias{rgl.postscript}
\title{Export vector graphics}
\description{
Saves the screenshot to a file in PostScript or other vector graphics format.
}
\usage{
rgl.postscript( filename, fmt = "eps", drawText = TRUE )
}
\arguments{
\item{filename}{full path to filename.}
\item{fmt}{export format, currently supported: ps, eps, tex, pdf, svg, pgf }
\item{drawText}{logical, whether to draw text}
}
\details{
Animations can be created in a loop modifying the scene and saving
a screenshot to a file. (See example below)
This function is a wrapper for the GL2PS library by Christophe Geuzaine,
and has the same limitations as that library: not all OpenGL features
are supported, and some are only supported in some formats.
See the reference for full details.
