When the filename reaches "gbPlt999.bmp", it will recycle to "gbPlt001.bmp".
You can use this to capture many images in a sequence - such as when you're
automatically rotating the gbPlot Enhanced image and want to capture
several images to support building an Automated GIF of the rotation.
Don't forget to save the list when you exist (gbPlot Enhanced will
automatically remind you to save any changes made to the equation list)!
VRML is used as the display file format. Every time a new image is displayed,
gbPlot creates a temporary file, 'gbPlot.wrl', which contains the VRML
code for that image. To save a particular display, simply rename the
gbPlot.wrl file to a name of your choice. Display of subsequent images
will recreate the gbPlot.wrl file as needed.
gbPlot consists of two windows, the Main window which contains the display
and a a Data window which contains the z values to be plotted (in a
spreadsheet format).

Special Features
If you've just completed adjusting a display to exactly the way you want
it you can save it for display in another session. But why wait? Use
the Edit/Set Wallpaper menu option to change the desktop wallpaper to
a centered image of what you see in gbPlot Enhanced.
Chose the Options/Slideshow menu option and watch gbPlot Enhanced cycle
endlessly through the complete list of equations. An approximate 2 second
delay is used between each image.
With gbPlot Enhanced you can have the image automatically rotated so
that you can see the 3D nature of the image. This feature saves you
a lot of time when you want to scroll through the equations, looking
for a particular image - by eliminating the need to use the mouse to
manually rotate each image.
When you pick the File/Save Image to File menu option, the freeware version
of gbPlot saves the image to a file that is always named "gbPlot.bmp".
With gbPlot Enhanced you can have the image file automatically named to
"gbPlt001.bmp", with subsequent saves incrementing the filename as
"gbPlt002.bmp", "gbPlt003.bmp", ...
Do you have your own list of equations to add to gbPlot Enhanced?
gbPlot Enhanced will add a list of equations from a simple text file
(which must be named "batch.txt", and which is located in the gbPlot folder).
Use the Equations/Batch Load Equations menu option to add the contents of
the text file to the existing equation list. This can be much faster than
loading the equations one at at time within gbPlot Enhanced.
Sample Equation Plots
Main Window
gbPlot allows the user to create a 3D plot using equations of the form
z=f(x,y). A default list of equations is supplied with gbPlot
and the user may edit that list, including the plot boundary parameters.
The built-in spreadsheet may also be used to input the z values to
be plotted, or those values may be imported from an Excel spreadsheet.
Toolbar
You will spend most of your time using the toolbar, which consists of the
following functions:
Menus
The menu options of the Main window are:
Additionally, right mouse clicking on the equation list will present
the following menu options which act on the equation list:
VRML Source Window
Each time the gbPlot display changes a file "gbPlot.wrl" is written with
the VRML code for the display. The VRML code is simple text and gbPlot uses
the Windows program Notepad to display the content of the file. To save
a copy of the .WRL file, simply use Notepad's 'File/Save As' menu function
to rename the file.
