Appendix B: Processing Libraries
In this Appendix we use the Processing libraries to create graphics programs in Java.
Processing is a language and integrated development environment. Processing is free and open source, and used by educators and artists worldwide.
Under the hood, the Processing language is actually a simplified
version of Java, and Processing sketches (programs) are compiled and
run on the Java Virtual Machine (JVM) using the standard Java
command-line tools javac and java. All
Processing functions, such as the size(),
fill(), ellipse(), etc. are packaged into
Java archive (.jar) files which are part of the
Processing installation.
