The package is currently in its infancy, and is subject to change. Comments or suggetions are encouraged. + +This document describes the basics of the \tdplot\ package and provides information about the various available commands. Examples are given where possible. + +\subsection{What \tdplot\ is} + +\tdplot\ provides commands to easily specify coordinate transformations for \tikzname, allowing for relatively easy plotting. I needed to draw accurate 3d vector images for a physics thesis, and this package was developed to meet this need. + +In a recent addition, the \verb|\tdplotsphericalsurfaceplot| renders three dimensional surfaces, where both the radius and the surface fill hue can be expressed as user-specified functions of $\theta$ and $\phi$. This command is discussed in Section \ref{sec:spherical_surface_plot}. + +\begin{figure}[h] + \begin{center} + \threedconventions + \end{center} + \caption{\tdplot\ coordinate and positive angle convention.}\label{fig:conventions} +\end{figure} + +In \tdplot, a right-handed coordinate system convention is used. In addition, all positive angles constitute a right-hand screw sense of rotation (see Figure \ref{fig:conventions}). This means that a positive rotation about a given axis refers to a clockwise rotation when viewing along the direction the axis, or counterclockwise when viewing against the direction of the axis. + +\subsection{What \tdplot\ is not} + +\tdplot\ does not, in general, consider polygons, surfaces, or object opacity. The one exception is the \verb|\tdplotsphericalsurfaceplot| command, specifically designed to render spherical polar surfaces. The \verb|\tdplotsphericalsurfaceplot| command is discussed in Section \ref{sec:spherical_surface_plot}. + +Tools like Sketch by Gene Ressler are better suited for more rigorous surface rendering. These can be found at \url{http://www.frontiernet.net/~eugene.ressler/} + +\subsection{Similar Work} + +To my knowledge, there is no other package available which allows straightforward rendering of 3d coordinates in \tikzname, directly in a \LaTeX\ document. Since this project is in its infancy, this may be subject to change based on feedback. + +\subsubsection{Sketch} + +The Sketch project can provide three-dimensional rendering of axes, points, and lines, but (as far as I understand the program) cannot draw arcs without using a series of line segments. Further, Sketch requires an external program to render the image, while \tdplot\ can be developed and maintained right in a \LaTeX\ document. + +\subsubsection{\TeX ample.net} + +There are a variety of \tikzname\ examples listed at \url{http://www.texample.net/tikz/examples}. Some of these examples gave me inspiration to make this package.

These commands and styles are described in Chapter \ref{cha:using_tdplot}. + + + + + + + + + +\chapter{Overview of 3d in \tdplot}\label{cha:overview3d} + +\section{\tikzname\ 3d Plotting} \label{sec:tikzplotting} + +When setting up a tikzpicture or a drawing style, the $x$, $y$, and $z$ axes can be specified directly in terms of the original coordinate system. The following example shows how a \texttt{tikzpicture} environment can be configured to use customized axes. + +\begin{shaded} +\begin{verbatim} +\begin{tikzpicture}[% + x={(\raarot cm,\rbarot cm)},% + y={(\rabrot cm, \rbbrot cm)},% + z={(\racrot, \rbcrot cm)}] +\end{verbatim} +\end{shaded} + +In this example, the terms \verb|\raarot| and so on specify how the coordinates are represented in the original \tikzname\ coordinate system, and are calculated by the \tdplot\ package. Note that units are explicitly required so \tikzname\ understands that these are absolute coordinates, not scales on the existing axis. See the PGF manual Version 2.00, section 21.2 on pages 217-218 for details on \tikzname\ coordinate transformations. + +\section{The \tdplot\ Main Coordinate System}\label{sec:main_theory} + +\tdplot\ offers two coordinate systems, namely the \emph{main} coordinate system $(x,y,z)$, and the \emph{rotated} coordinate system $(x',y',z')$. The latter system is described in Section \ref{sec:rotated_theory}. + +As the name suggests, the main coordinate system provides a user-specified transformation to render 3d points in a \texttt{tikzpicture} environment. The orientation of the main coordinate system is defined by the angles $\theta_{d}$ and $\phi_{d}$. In the unrotated ($\theta_{d} = \phi_{d} = 0$) position, the $xy$ plane of the main coordinate system coincides with the default orientation for a \texttt{tikzpicture} environment, while $z$ points ``out of the page''. +% +The coordinate system is positioned by the following operations: +% +\begin{itemize} + \item Rotate the coordinate system about the body $x$ axis by the amount $\theta_d$, and + \item Rotate the coordinate system about the (rotated) body $z$ axis by the amount $\phi_d$. +\end{itemize} + +In this rotation sense, the $z$ axis will always point in the vertical page direction. This transformation is given by the rotation matrix $R_d(\theta_d,\phi_d)$, as +% +\begin{align}\begin{split} + R^d(\theta_d,\phi_d) &= R^{z'}(\phi_d)R^{x}(\theta_d)\\ + &= \begin{pmatrix} + \cos\phi_d & -\sin\phi_d & 0\\ + \sin\phi_d & \cos\phi_d & 0\\ + 0 & 0 & 1 + \end{pmatrix} + \begin{pmatrix} + 1 & 0 & 0\\ + 0 & \cos\theta_d & -\sin\theta_d\\ + 0 & \sin\theta_d & \cos\theta_d\\ + \end{pmatrix}\\ + &= \begin{pmatrix} + \cos\phi_d & \sin\phi_d & 0\\ + -\cos\theta_d\sin\phi_d & \cos\theta_d\cos\phi_d & -\sin\theta_d\\ + \sin\theta_d\sin\phi_d & -\sin\theta_d\cos\phi_d & \cos\theta_d\\ + \end{pmatrix} +\end{split}\end{align} + +\begin{figure}[b] + \begin{center} + \threedcoord{0}{0} + \threedcoord{10}{50} + \threedcoord{30}{110} + + \threedcoord{40}{150} + \threedcoord{60}{170} + \threedcoord{90}{180} + \end{center} + \caption{Examples of coordinate systems for various choices of $\theta_d$ and $\phi_d$.} +\end{figure} + +Using this matrix, the \tikzname\ coordinate transformation can be applied as described in Section \ref{sec:tikzplotting} by the various matrix elements, as +% +\begin{align}\begin{split} + x &= (R^d_{1,1}, R^d_{2,1})\\ + y &= (R^d_{1,2}, R^d_{2,2})\\ + z &= (R^d_{1,3}, R^d_{2,3}) +\end{split}\end{align} + +Note that the third row of the rotation matrix is not needed for this transformation, since a screen coordinate is a 2d value. Once the transformed axes have been established, any 3d coordinate specified in \tikzname\ will adhere to the transformation, yeilding a 3d representation. Lines and nodes can readily be drawn by using these 3d coordinates. + +This coordinate transformation is accessible through \tdplot\ using the command \texttt{tdplotsetmaincoords}, as described in Chapter \ref{cha:using_tdplot}. + +\section{The \tdplot\ Rotated Coordinate System}\label{sec:rotated_theory} + +Along with the main coordinate system, described in Section \ref{sec:main_theory}, \tdplot\ offers a \emph{rotated} coordinate system that is defined with respect to the main coordinate system. This system can be rotated to any position using Euler rotations, and can be translated so the origin of the rotated coordinate system sits on an arbitrary point in the main coordinate system. + +Three rotations can be performed to give any arbitrary orientation of a rotated coordinate system. By convention, the following rotations are chosen: +% +\begin{itemize} + \item Rotate by angle $\gamma$ about the world $z$ axis, + \item Rotate by angle $\beta$ about the (unrotated) world $y$ axis, and + \item Rotate by angle $\alpha$ about the (unrotated) world $z$ axis. +\end{itemize} + +These rotations are shown in Figure \ref{fig:euler_angles}. + +\begin{figure}[h] + \begin{center} + \threedalphabetagamma + \end{center} + \caption{Positioning the rotated coordinate frame $(x', y', z')$ using Euler angles $(\alpha, \beta, \gamma)$.}\label{fig:euler_angles} +\end{figure} + + +This rotation matrix $D(\alpha,\beta,\gamma)$ is given by +% +\begin{align}\begin{split} + D(\alpha,\beta,\gamma) &= R^z(\alpha)R^y(\beta)R^z(\gamma)\\ + &= \begin{pmatrix} + \cos\alpha & -\sin\alpha & 0\\ + \sin\alpha & \cos\alpha & 0\\ + 0 & 0 & 1\\ + \end{pmatrix} + \begin{pmatrix} + \cos\beta & 0 & \sin\beta \\ + 0 & 1 & 0 \\ + -\sin\beta & 0 & \cos\beta\\ + \end{pmatrix} + \begin{pmatrix} + \cos\gamma & -\sin\gamma & 0\\ + \sin\gamma & \cos\gamma & 0\\ + 0 & 0 & 1\\ + \end{pmatrix}\\ + &= \begin{pmatrix} + \cos\alpha\cos\beta\cos\gamma - \sin\alpha\sin\gamma & -\cos\alpha\cos\beta\sin\gamma - \sin\alpha\cos\beta & \cos\alpha\sin\beta\\ + \sin\alpha\cos\beta\cos\gamma + \cos\alpha\sin\gamma & -\sin\alpha\cos\beta\sin\gamma + \cos\alpha\cos\gamma & \sin\alpha\sin\beta\\ + -\sin\beta\cos\gamma & \sin\beta\sin\gamma & \cos\beta + \end{pmatrix} +\end{split}\end{align} + +To define the rotated coordinate frame, this rotation matrix is applied after rotation matrix $R^d(\theta_d,\phi_d)$ used to define the main coordinate frame. The full transformation for the rotated coordinate frame is then given by +% +\begin{align} + R'^d(\theta_d,\phi_d,\alpha,\beta,\gamma) &= D(\alpha,\beta,\gamma)R^d(\theta_d,\phi_d) +\end{align} + +Using this matrix, the \tikzname\ coordinate transformation can be applied as described in Section \ref{sec:tikzplotting} by the various matrix elements, as +% +\begin{align}\begin{split} + x' &= (R'^d_{1,1}, R'^d_{2,1})\\ + y' &= (R'^d_{1,2}, R'^d_{2,2})\\ + z' &= (R'^d_{1,3}, R'^d_{2,3}) +\end{split}\end{align} + +This coordinate transformation is accessible through \tdplot\ using the command \texttt{tdplotsetrotatedcoords}, as described in Chapter \ref{cha:using_tdplot}. + +\begin{figure}[h] + \begin{center} + \threedrotcoordsystem + \end{center} + \caption{The rotated coordinate frame $(x', y', z')$ displayed within the main coordinate frame $(x,y,z)$. Both are completely specified by user-defined angles: $(\theta_d, \phi_d)$ for the main coordinate frame, and $(\alpha, \beta, \gamma)$ for the rotated coordinate frame.} +\end{figure} + + +\section{Arcs in 3d, and the ``Theta Plane''} + +Arcs can be drawn in \tikzname\ using commands described in the PGF manual Version 2.00, section 2.10 on pages 25-26. However, the arc commands accept 2d coordinates, and thus can only be drawn in the $xy$ plane. + +To draw an arc in any position other than within the $xy$ plane of the main coordinate frame, the rotated coordinate frame must be used, where the $x'y'$ plane lies in the desired orientation within the main coordinate frame. Such an arc is needed, for example, when illustrating the polar angle $\theta$ of some vector. This $\theta$ arc exists in a plane which contains the $z$ axis, and is rotated about the $z$ axis by the angle $\phi$ from the $xz$ plane. For lack of a better name, this plane is referred to as the ``theta plane'' within a given coordinate system. + +\begin{figure}[h] + \begin{center} + \threedthetaarc + \end{center} + \caption{Drawing arcs outside the $xy$ plane by using a rotated coordinate frame in the ``theta plane'' of the main coordinate frame.} +\end{figure} + +As described in Chapter \ref{cha:using_tdplot}, \tdplot\ offers the commands \texttt{tdplotsetthetaplanecoords} and \texttt{tdplotsetrotatedthetaplanecoords} to easily configure the rotated coordinate frame to lie within the desired theta plane. + + + + + + + + +\chapter{Using the \tdplot\ Package} \label{cha:using_tdplot} + +The \tdplot\ package was developed to handle the number crunching described in Chapter \ref{cha:overview3d}, and provide a relatively simple and straightforward frontend for users. + +The main and rotated coordinate frames are configured by using commands described in Section \ref{sec:tdplotcommands}. These commands generate \tikzname\ styles which can be used either in defining the \texttt{tikzpicture} environment, or directly in any \tikzname\ command. The styles are described further in Section \ref{sec:tikzstyles}. + +\section{The \tdplot\ \tikzname\ Styles} \label{sec:tikzstyles} + + +\subsection{\texttt{tdplot\_main\_coords}} + +The \verb|tdplot_main_coords| style stores the coordinate transformation required to generate the main coordinate system.

This is useful to escape out of the user-defined 3d coordinates used at the beginning of the \texttt{tikzpicture} environment, and place something on an absolute scale in the figure. Tables, legends, and captions contained within the same figure as a 3d plot can make use of this style. + +\section{The \tdplot\ Commands} \label{sec:tdplotcommands} + +This section lists the various commands provided by the \tdplot\ package.

This division provides a cheap and dirty way of ensuring the surface on the far side of the viewing perspective is drawn first, ensuring proper opacity and object occlusion. + +For a given perspective assigned by the main coordinate frame, a ``view orientation'' can be defined, giving the angles $(\theta_{view},\phi_{view})$ that describe the orientation of the view. These angles determine how to dubdivide the surface rendering process. The following divisions are made: +% +\begin{itemize} + \item Divide the surface into ``front'' and ``back'', where the back is drawn before the front. + \item Subdivide into ``left'' and ``right'' + \item Subdivide further into ''top'' and ''bottom'' +\end{itemize} + +The entire back half is drawn before the front front half. For each half, the entire left or right side is drawn. For each side, the theta angles are drawn for each angle of phi. When on the back half, the theta angle is swept from $\theta_{view}$ toward the poles. When on the front half, the theta angle is swept from the poles toward $\theta_{view}$. + +To improve the illusion of proper depth perception, a set of commands can be specified to render the $x$, $y$, and $z$ axis.
