 \section{Overview of the \tdplot\ Package}
-The \tdplot\ package offers commands and coordinate tranformation styles for \tikzname, providing relatively straightforward tools to draw three-dimensional coordinate systems and simple three-dimensional diagrams.  The package is currently in its infancy, and is subject to change.  Comments or suggetions are encouraged.

 \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.
 
-Various plotting commands are used to itentify coordinate locations using spherical polar or cartesian coordinates.  Coordinate transformation commands allow for the calculation of a coordinate in one frame based on its values in another frame.  Some drawing commands have been developed to assist in the rendering of arcs.  These commands do the number crunching required to position and render the arcs.  These commands are discussed in Section \ref{sec:tdplotcommands}.

 In addition, the \verb|\tdplotsphericalsurfaceplot| was developed to render three-dimensional surfaces in spherical polar coordinates, where the radius is expressed in terms of a user-defined function of $\theta$ and $\phi$.  With this function, the surface hue can be given explicitly, or expressed as a user-defined function of $r$, $\theta$, and $\phi$.  This command is discussed in Section \ref{sec:spherical_surface_plot}.

-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.

 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}.
