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.

Writing Processing libraries


Now that you've installed the library template, it's time to get your hands dirty and write some Java. We'll write a small library that can draw hexagons and stars. Nothing fancy, just something small to give you an idea of how libraries are made.

Getting ready

If you haven't installed the Processing library template, you should do this first. The process is explained in the previous recipe, Installing the Processing library template in Eclipse.

How to do it...

Go to the src directory of your library project in the Package Explorer in Eclipse. You can delete everything in that folder. Select the src directory, and go to the File | New | Class menu to create a new Java class. In the package field, you can type the URL of your website backwards. This will be useful when you import the library into your Processing sketch. In the Name field, you can type MyLib, the name of the class we'll write. Once you have done this, you can create the new file by clicking the Finish...
