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.

Playing a video


This will be the most basic recipe in this chapter. You'll learn how to load a video file from the hard drive and play it on the screen.

Getting ready

Start a new Processing sketch, and save it in your sketch folder as playing_video.pde. Add a video file to the data folder of the sketch by dragging the video file onto the Processing window. I've used the marbles.mov file for all examples; you can use this one too, if you like. This video file should be in the data folder of your Processing sketch. You can add it by dragging the file onto the PDE.

How to do it...

You need to start by importing the video library. Go to Sketch | Import Library | video, to do this. You also need to declare a Movie object, right before the setup() function. Inside the setup() function, you'll load the video file from the hard drive, and set the video to loop.

import processing.video.*;
  
Movie m;
  
void setup()
{
  size( 640, 480 );
  
  m = new Movie( this, "marbles.mov" );
  m.loop();
}
