The Surface Plotter version 1.10 


Surface Plotter 1.10 helps you to visualize mathematical surfaces defined by an explicit
two-variable function (e.q:  z = f(x,y)). You can interactively rotate, tilt, scale or move the
surface once it was calculated and plotted. 
Surface Plotter was written in Java programming language, and was designed to be both an applet
and a standalone application.


Supported platforms
-------------------
Surface Plotter supports all platforms that support Java. 
You need a Java-enabled Web browser (Netscape 2.0, Microsoft Internet Explorer 3.0, HotJava)
or appletviewer of Java Development Kit (JDK). If you have JDK, you can run
Surface Plotter as an application using a java interpreter included in the JDK. 
This version of Surface Plotter was compiled using JDK version 1.0.2. 
For the present time, the JDK is available for SPARC Solaris, x86 Solaris, Windows NT, 
Windows 95, Mac, and Linux. 
  

Installation Instruction
------------------------
Surface Plotter comes in three compression formats: gzip, Z and zip. All these files contain
the same set of files, so choose only one of it. (UNIX users might prefer gzip or Z format,
while Macintosh and Windows users might prefer zip format)
If you choose gzip or Z format, first copy the distribution file to the directory under which 
you want to install the Surface Plotter and change directory to the directory. 
Then type the following command:

           gunzip SurfacePlotter110.tar.gz | tar xvf -        (gzip format)
           
                            or
                            
           zcat SurfacePlotter110.tar.Z | tar xvf -           (Z format)
           
If you are Windows or Macintosh user, choose the zip compressed file and uncompressed it an 
unzip program. (It is not a self-extract zip file). For Windows 95 users, make sure that your unzip 
program supports long file name format. 
The Surface Plotter will be installed under "surface" directory of current or selected directory. 
This "surface" directory is the Surface Plotter directory.           
           
Running Surface Plotter
-----------------------
The Surface Plotter directory contains Surface Plotter *.html files, images directory, classes directory, 
and sources directory. 
To run the Surface Plotter as an applet, first run you Web browser (Must be Java enabled) and load
a file named "surface.html". The Web browser will automatically load the Surface Plotter for you.
To run the Surface Plotter as an application, you need a JDK version beta1 or later (I suggest the
latest version) installed on your machine. The easiest way is change the current working directory to
the "classes" directory (under installation directory) and execute this command:

     java surface
     
This will load the surface class and execute it. If you got an error message that tells you that
a particular class could not be found, make sure that your CLASSPATH contains the Surface Plotter
"classes" directory or current working directory. For example:

     CLASSPATH=.;C:\JAVA\LIB
     
tells Java interpreter to search for classes in current working directory and C:\JAVA\LIB directory.
If you have JDK installed on your machine, and you don't have Java enabled Web browser, you can run
Surface Plotter using the appletviewer. Go to the directory where surface.html is installed 
(Surface Plotter directory) and execute this command:
  
     appletviewer surface.html
