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.

Installing the OpenCV library


Until now, we've only used the standard Processing video library to do some basic computer vision. If you want to do some more advanced stuff, such as face recognition, you'll need to use the OpenCV library.

How to do it...

OpenCV for Processing and Java is available for Mac OS X, Windows, and Linux. Everything you need to install the library can be found at http://ubaa.net/shared/processing/opencv/.

The first thing you need to do is install OpenCV. On Windows, you need to download the OpenCV release version 1.0 package and install everything on your computer. For Mac OS X, there is an OpenCV framework 1.1 available. Download the DMG file, open it, and install the package. On Linux, you need to download the OpenCV archive and compile/install everything yourself.

The second step in this process is to download the OpenCV Processing library, unzip it, and drag the folder to your Processing libraries folder. The folder structure should look like the following screenshot...
