Processing 2: Creative Programming Cookbook

Overview of this book

Processing is probably the best known creative coding environment that helps you bridge the gap between programming and art. It enables designers, artists, architects, students and many others to explore graphics programming and computational art in an easy way, thus helping you boost your creativity. "Processing 2: Creative Programming Cookbook" will guide you to explore and experience the open source Processing language and environment, helping you discover advanced features and exciting possibilities with this programming environment like never before. You'll learn the basics of 2D and 3D graphics programming, and then quickly move up to advanced topics such as audio and video visualization, computer vision, and much more with this comprehensive guide. Since its birth in 2001, Processing has grown a lot. What started out as a project by Ben Fry and Casey Reas has now become a widely used graphics programming language. Processing 2 has a lot of new and exciting features. This cookbook will guide you to explore the completely new and cool graphics engine and video library. Using the recipes in this cookbook, you will be able to build interactive art for desktop computers, Internet, and even Android devices! You don't even have to use a keyboard or mouse to interact with the art you make. The book's next-gen technologies will teach you how to design interactions with a webcam or a microphone! Isn't that amazing? "Processing 2: Creative Programming Cookbook" will guide you to explore the Processing language and environment using practical and useful recipes.

Importing the Minim library


The first thing you'll need to do for every sketch in this chapter is to import the minim library. You'll learn all about Minim in this recipe.

How to do it...

Create a new sketch and go to Sketch | Import Library | minim. The following lines will be added at the top of your document.

import ddf.minim.*;
import ddf.minim.signals.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;

How it works...

The minim library contains four packages. These contain specific classes to work with a certain aspect of audio. You don't usually need to import all of them into your sketch.

  • ddf.minim.*: This contains the main Minim classes. You'll need to import this one in every sketch where you want to use the minim library. This package allows you to play audio files and work with the microphone input of your computer.

  • ddf.minim.signals.*: This contains an oscillator and some wave generators to create sine waves, saw waves, and so on. This package is mostly used to create synthesizers...
