-% \section{introduction}
-%
-% The base package \texttt{pstricks} already disposes of some macros with which three
-% dimensional effects can be obtained.
-% There are several packages though which support the creation of three
-% dimensional objects or functions. A compilation is shown in
-% table~\ref{tab:pst3d:pakete}. Here already several of the packages overlap, for
-% parallel developments are nothing unusual in the \TeX{} world. Although
-% \verb+pst-3d+ is one of the older packages, it shall be dealt with nevertheless,
-% for it also contains the preliminary stage of the 3D representations, that is
-% shadow creation and tilting.
-%
-% \begin{table}[htb]
-% \caption{Summary of all 3D packages}\label{tab:pst3d:pakete}
-% \centering
-% \begin{tabular}{ll}
-% \emph{package} & \emph{content}\\\hline
-% \texttt{pst-3d}     & basic 3D operations\\
-% \texttt{pst-3dplot} & Three dimensional plots\\
-% \texttt{pst-fr3d}   & Three dimensional framed Boxes\\
-% \texttt{pst-gr3d}   & 3D grids\\
-% \texttt{pst-map3dII}& 3D Geographical Projection\\
-% \texttt{pst-ob3d}   & Three dimensional basic objects\\
-% \texttt{pst-vue3d}  & Three dimensional views\\
-% \end{tabular}
-% \end{table}
-%
-%
-% \section{Shadow}\label{sec:pst3d:schattenwurf}
-% \verb+pst-3d+ defines the macro \verb+\psshadow+ with the following syntax:
-% \begin{verbatim}
-% \psshadow[<parameters>]{<material>]
-% \end{verbatim}
-% As parameters the ones given in table~\ref{tab:pst-3d:schattenparameter} are
-% available next to all previously defined, if they have a meaning for the
-% material to be shadowed. This can be anything text-like, text, rules and
-% mathematical expressions in inline mode.
-% 
-% \medskip
-% \begin{SideBySideExample}[xrightmargin=.35\linewidth]

-%   \psshadow[Tshadowsize=2.5]{%
-%     \rule{2cm}{10pt}}
-% \end{SideBySideExample}
-% 
-% \subsection{Parameters}\label{subsec:pst3d:schattenparameter}
-% Table~\ref{tab:pst-3d:schattenparameter} shows a compilation of the used
-% parameters.
-% 
-%
-%
-%

-% Tshadowcolor & <colour> & lightgray\\
-% Tshadowsize & <value> & 1
-% \end{tabular}
-% \end{table}
-% 
-% 
-% \subsubsection{\texttt{Tshadowangle}}\label{subsubsec:pst3d:tshadowangle}
-% \verb+Tshadowangle+ denotes the angle of the shadow,
-% referring to the perpendicular of the paper plane. The angle of $90$° therewith
-% corresponds to the text itself. Negative angles cause the shadow to arise
-% from the paper plane.
-

-% \begin{itemize}
-% 	\item Angular values of $0$° and $180$° are not allowed.
-% \end{itemize}
-% 
-% 
-% 
-% \subsubsection{\texttt{Tshadowcolor}}\label{subsubsec:pst3d:tshadowcolor}
-% \verb+Tshadowcolor+ deontes the shadow colour.
-% 
-% \begin{SideBySideExample}[xrightmargin=.25\linewidth]
-%   \psshadow{\huge shadow}\\[5pt]
-%   \psshadow[Tshadowcolor=red]{\huge shadow}\\[5pt]
-%   \psshadow[Tshadowcolor=green]{\huge shadow}\\[5pt]
-%   \psshadow[Tshadowcolor=blue]{\huge shadow}
-% \end{SideBySideExample}
-% 
-% 
-% \subsubsection{\texttt{Tshadowsize}}\label{subsubsec:pst3d:tshadowsize}
-% \verb+Tshadowsize+ determines the size of the
-% shadow\index{shadow!size} as a scaling factor\index{scaling factor}.
-% 
-% \begin{SideBySideExample}[xrightmargin=.25\linewidth]
-%   \psshadow{\Huge shadow}\\[5pt]
-%   \psshadow[Tshadowsize=0.5]{\Huge shadow}\\[10pt]

-% \section{Tilting}\label{sec:pst3d:kippen}
-% With the tilting of objects the
-% perspective views of three dimensional objects can be simulated. \verb+pst-3d+
-% defines two macros for this.
-% 
-% \begin{verbatim}
-% \pstilt[<parameters>]{<angle>}{<material>}
-% \psTilt[<parameters>]{<angle>}{<material>}
-% \end{verbatim}
-% 
-% Figure~\ref{fig:pst3d:demo} shows the difference between these two macros.
-% Principally everything can be given as argument to those macros and therewith
-% tilted. With vertical material, as distinguished formulae, eventually the
-% argument has to be put into a \verb+\parbox+ before (see
-% example),

-% \verb+pst-3d+ only supports parallel projections, so that geometrical objects
-% such as spheres or cylinders can only be displayed restricted. Although

-% For figure~\ref{fig:pst3d:viewpoint} a viewpoint of \verb+viewpoint=3 5 2+ was
-% defined. If one desires to regard it for instance from the $y$ axis from a
-% larger height, \verb+viewpoint=0 1 3+ could be chosen. The viewer has moved one
-% unit in $y$ direction and four units in $z$ direction from the centre (origin)
-% and regards everything from there.  
-% 
-% 
-% \medskip
-% \begin{itemize}
-% 	\item The \verb+viewpoint+ principally \textbf{has} to be defined with
-% 		values not equal to zero, for this would lead to a division by zero.
-% 		Specifications of $0.001$ for a coordinate are already sufficing to
-% 		escape the division by zero and blind out the coordinate.
-% \end{itemize}
-% 
-% A good value for the viewpoint would be \verb+viewpoint=1 1 0.5+ for instance,
-% which corresponds to a horizontal rotation by 45° and a vertical by ca. 20°.
-% Another meaningful point is also \verb+viewpoint=1.5 1 0.5+, which now

-% \item[\cs{ThreeDput(0,0,0)\{\textbackslash psframe*[linecolor=gray80](4,4)\}}:]
-% 	puts a square with a side length of four into the origin of ordinates with
-% 	the lower left edge. Since no normal vector is specified here, the default
-% 	value $\vec{n}=(0,0,1)$ is taken, wherewith the area is positioned in the
-% 	first quadrant of the $xy$ plane.
-% \item[\cs{ThreeDput(2,2,0)\{\textbackslash huge\textbackslash psrotatedown\{xy-plane\}\}}:]
-% 	puts the text rotated by $180$° centric to the point $(2,2,0)$ in the

-% \subsection{Basic 3D transformations}
-%
-% \begin{macro}{\tx@SetMatrixThreeD}
-%    Viewpoint for 3D coordinates is given by three angles: $\alpha$, $\beta$ and
-%    $\gamma$. $\alpha$ and $\beta$ determine the direction from which one is
-%    looking. $\gamma$ then determines the orientation of the observing.
-%    When $\alpha$, $\beta$ and $\gamma$ are all zero, the observer is looking
-%    from the negative part of the $y$-axis, and sees the $xz$-plane the way in
-%    2D one sees the $xy$ plan. Hence, to convert the 3D coordinates to their 2D
-%    project, $\langle x, y, z\rangle$ map to $\langle x, z\rangle$.
-%    When the orientation is different, we rotate the coordinates, and then
-%    perform the same projection.
-%    We move up to latitude $\beta$, over to longitude $\alpha$, and then rotate
-%    by $\gamma$. This means that we first rotate around $y$-axis by $\gamma$,
-%    then around $x$-axis by $\beta$, and the around $z$-axis by $\alpha$.
-%
-%    Here are the matrices:
-%    \begin{eqnarray*}
-%    R_z(\alpha) & = & \left[
-%     \begin{array}{ccc}
-%       \cos \alpha & -\sin \alpha & 0 \\
-%       \sin \alpha & cos \alpha   & 0 \\
-%       0           & 0            & 1
-%     \end{array} \right] \\
-%   R_x(\beta) & = & \left[
-%     \begin{array}{ccc}
-%       1           & 0            & 0 \\
-%       0           & \cos \beta   & \sin \beta \\
-%       0           & -\sin \beta  & \cos \beta
-%     \end{array} \right] \\
-%   R_y(\gamma) & = & \left[
-%     \begin{array}{ccc}
-%       \cos \gamma & 0            & -\sin \gamma \\
-%       0           & 1            & 0 \\
-%       \sin \gamma & 0            & \cos \gamma
-%     \end{array} \right]
-% \end{eqnarray*}
-%
-% The rotation of a coordinate is then performed by the matrix $R_z(\alpha)
-% R_x(\beta) R_y(\gamma)$. The first and third columns of the matrix are the
-% basis vectors of the plan upon which the 3D coordinates are project (the old
-% basis vectors were $\langle 1, 0, 0\rangle$ and $\langle 0, 0, 1\rangle$; rotating these
-% gives the first and third columns of the matrix).
-%
-% These new base vectors are:
-% \begin{eqnarray*}
-%   \tilde{x} & = & \left[
-%     \begin{array}{c}
-%       \cos\alpha \cos\gamma - \sin\beta \sin\alpha \sin\gamma \\
-%       \sin\alpha \cos\gamma + \sin\beta \cos\alpha \sin\gamma \\
-%       \cos\beta \sin\gamma
-%     \end{array} \right] \\
-%   \tilde{z} & = & \left[
-%     \begin{array}{c}
-%       -\cos\alpha \sin\gamma - \sin\beta \sin\alpha \cos\gamma \\
-%       -\sin\alpha \sin\gamma + \sin\beta \cos\alpha \cos\gamma \\
-%       \cos\beta \cos\gamma
-%     \end{array} \right]
-% \end{eqnarray*}
-%
-% Rather than specifying the angles $\alpha$ and $\beta$, the user gives a
-% vector indicating where the viewpoint is. This new viewpoint is the rotation
-% o the old viewpoint. The old viewpoint is $\langle 0, -1, 0\rangle$, and so the new
-% viewpoint is
-% \[
-%  R_z(\alpha) R_x(\beta) \left[ \begin{array}{c} 0\\-1\\0 \end{array} \right]
-%  \, = \,
-%  \left[ \begin{array}{c}
-%    \cos\beta \sin\alpha \\
-%    -\cos\beta \cos\alpha \\
-%    \sin\beta
-%  \end{array} \right]
-%  \, = \,
-%  \left[ \begin{array}{c} v_1 \\ v_2 \\ v_3 \end{array} \right]
-% \]
-% Therefore,
-% \begin{eqnarray*}
-%   \alpha & = & \arc\tan (v_1 / -v_2) \\
-%   \beta & = & \arc\tan (v_3 \sin\alpha / v_1)
-% \end{eqnarray*}
-% Unless $p_1=p_2=0$, in which case $\alpha=0$ and $\beta=\sign(p_3)90$, or
-% $p_1=p_3=0$, in which case $\beta=0$.
-%
-% The syntax of \verb+SetMatrixThreeD+ is
-% \[
-%   v_1\ v_2\ v_3\ \gamma\ \mathrm{SetMatrixThreeD}
-% \]
-% \verb+SetMatrixThreeD+ first computes
-% \[
-%   \begin{array}{ll}
-%     a=\sin\alpha & b=\cos\alpha\\
-%     c=\sin\beta  & d=\cos\beta\\
-%     e=\sin\gamma & f=\cos\gamma
-%   \end{array}
-% \]
-% and then sets \verb+Matrix3D+ to \verb+[+$\tilde{x}$ $\tilde{z}$\verb+]+.

-% To embed 2D $\langle x, y\rangle$ coordinates in 3D, the user specifies the normal
-% vector and an angle. If we decompose this normal vector into an angle, as
-% when converting 3D coordinates to 2D coordinates, and let $\hat\alpha$,
-% $\hat\beta$ and $\hat\gamma$ be the three angles, then when these angles are
-% all zero the coordinate $\langle x, y\rangle$ gets mapped to $\langle x, 0, y\rangle$, and
-% otherwise $\langle x, y\rangle$ gets mapped to
-% \[
-%   R_z(\hat\alpha) R_x(\hat\beta) R_y(\hat\gamma)
-%   \left[ \begin{array}{c} x \\ 0 \\ y \end{array} \right]

-%   \end{array} \right]
-% \]
-% where $\hat{x}$ and $\hat{z}$ are the first and third columns of $R_z(\hat\alpha) R_x(\hat\beta) R_y(\hat\gamma)$.
-%
-% Now add on a 3D-origin:

-%   \end{array} \right]

-% \begin{align*}
-%   x' & =  \tilde{x}_1(\hat{x}_1 x + \hat{z}_1 y + x_0) +
-%            \tilde{x}_2(\hat{x}_2 x + \hat{z}_2 y + y_0) +
-%            \tilde{x}_3(\hat{x}_3 x + \hat{z}_3 y + z_0)\\
-%   & =

-%   + \tilde{x}_1 x_0 + \tilde{x}_2 y_0 + \tilde{z}_3 z_0\\
-%   y' & =  \tilde{z}_1(\hat{x}_1 x + \hat{z}_1 y + x_0) +
-%            \tilde{z}_2(\hat{x}_2 x + \hat{z}_2 y + y_0) +
