============================
Particles3D.java

-----
Compilation:

$ javac *.java
    // you must have Java 3D installed for the compilation to succeed;
    // if you get "Warning" messages, please see the note below


Java 3D is available from http://java.sun.com/products/java-media/3D/

-----
Execution: 

Use the Particles3D.bat batch file.

You supply up to two arguments which set the number of
particles and the type of particles.
    Type Number		meaning
       1		  points
       2		  lines
       3		  quads


e.g.
$ Particles3D 6000 3
     - means 6000 particles as quads (= 1500 quads)


$ Particles3D
     - means the default: 3000 particles as points (= 3000 points)


$ Particles3D 4000
     - means 4000 particles as points

Note on "unchecked or unsafe operation" Warnings

As explained in chapter 3, I have not used J2SE 5.0's type-safe 
collections, so that this code will compile in early versions of
J2SE (e.g. version 1.4).

The warning messages are always related to my use of collections
(e.g. ArrayList) without specifying a type for the objects they will
contain at run time.

No. of Warnings generated in J2SE 5.0 for the examples:
/Particles3D: 9 warnings
