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.

Using a webcam


The first thing you need to learn is displaying the video from your webcam, on the screen. Processing makes this very easy for you. You'll be up and running in no time, by writing a few lines of code.

How to do it...

The code for this example is really short. You need to start by importing the video library that is included with Processing. Go to Sketch | Import Library | video, to do this. You also need to declare an object of the Capture type. This object will be used to access the webcam on your computer.

import processing.video.*;
  
Capture webcam;

Inside the setup() function, you need to initialize the Capture object with the settings you need and start capturing. In the draw() function, we'll draw the current image from the webcam to the screen.

void setup()
{
  size( 640, 480 );
  smooth();
    
  println( Capture.list() );
    
  webcam = new Capture( this, width, height, 30 );
  webcam.start();
}

void draw()
{
  background( 255 );
  image( webcam, 0, 0 );
}

The last function...
