\item[Window title:]  DsTool: Geomview threeD interface
\item[Function:] The 3-D View window allows the user to graphically display computed data
	in Geomview\index{Geomview}.
%serves as an interface to Geomview, through which three dimensional plots can be made of computed data.
\item[Description:] The 3-D View window is opened by selecting the Three-D (Geomview) option
	from the Panels menu button located in the Command window.  
        The 3-D View window can always be opened, regardless of the number of phase space variables
        of the system, however only one 3-D View window may be opened.
        The user can select
        the plotting coordinates from all available variables, parameters, and auxiliary functions
        of the current dynamical system, or plotting coordinates can be set to ``0''.

 	Unlike the 2-D and 1-D View windows, data is not displayed as it is computed. 
	The data must be computed first, and then sent to Geomview.  In addition to the 
	data points which are sent, Geomview will display a bounding box which corresponds
	to the product of the default ranges of the plotting coordinates.  

\item[Panel items:] \mbox{}
	\begin{itemize}
	\item X-axis stack setting:
		Allows the user to choose the coordinate of the abscissa.   The user
		may choose between all variables (including the independent variable), 
		parameters, and auxiliary functions, or the setting ``0''.  This 
		last choice is useful for generating two or one dimensional plots in 
		Geomview.
% (and alternate coordinate systems if the user has specified them).   
	\item Y-axis stack setting:
		Allows the user to choose the coordinate of the ordinate.   The choices
		are the same as those for the X-axis.
	\item Z-axis stack setting:
		Allows the user to choose the coordinate of the vertical axis.   The choices
		are the same as those for the X-axis.
	\item Pick color exclusive setting:\index{color, pick}
                Allows the user to choose whether points which are plotted in
		Geomview will be colored by the pick color or by the alternating color.
		The default is to use the alternating color.
	\item Connect dots exclusive setting:\index{connect the dots}
		Allows the user to chooose whether points which are plotted in Geomview 
		will be connected by lines or not.  
		The default is to not connect the dots.
	\item Send to geomview command/window button:
		Invokes Geomview\index{Geomview} to display a three dimensional plot with the specified
		options.  
	\item Dismiss command button:
		Closes the 3-D View window.  
%The settings will not revert to their default values.
