Learn how to write a Java class that uses color to plot 3D surfaces in six different formats and a wide range of sizes. The class is extremely easy to use. You can incorporate the 3D plotting capability into your own programs by inserting a single statement into your programs.

Preface

In one of my earlier modules titled Plotting Engineering and Scientific Data using Java , I published a generalized 2D plotting program that makes it easy to cause other programs to display theiroutputs in 2D Cartesian coordinates . I have used that plotting program in numerous modules since I originally published it several years ago. Hopefully, some of my readershave been using it as well.

In this module, I will present and explain a 3D surface plotting program that is also very easy to use.

Numerous Java graphics libraries are available from various locations on the web. Some are of high quality, and some are not. Unfortunately, many of thoselibraries have a rather substantial learning curve.

The purpose of this program

It is not the purpose of the class that I will provide in this module to compete with those graphics libraries. Rather, this class is intended to make itpossible for an experienced Java programmer to incorporate 3D surface plotting capability into a Java program with a learning curve of three minutes or less.

(If you are an experienced Java programmer, you can start your three-minute learning-curve clock right now. If you are not an experiencedJava programmer, it may take a little longer but should still be easy. If you need to work on your Java programming skills, see Object-Oriented Programming (OOP) with Java .)
