Overview of this book

openFrameworks is a powerful programming toolkit and library designed to assist the creative process through simplicity and intuitiveness. It's a very handy software library written in C++ to reduce the software development process, helping you to kick-start creative coding. With the help of C++ and shaders support, openFrameworks allows for the processing of all kinds of media information with your custom-developed algorithms at the lowest possible level, with the fastest speed. "Mastering openFrameworks: Creative Coding Demystified" will introduce you to a world of creative coding projects, including interactive installations, audio-visual, and sound art projects. You will learn how to make your own projects using openFrameworks. This book focuses on low-level data processing, which allows you to create really unique and cutting-edge installations and projects. "Mastering openFrameworks: Creative Coding Demystified" provides a complete introduction to openFrameworks, including installation, core capabilities, and addons. Advanced topics like shaders, computer vision, and depth cameras are also covered. We start off by discussing the basic topics such as image and video loading, rendering and processing, playing sound samples, and synthesizing new sounds. We then move on to cover 3D graphics, computer vision, and depth cameras. You will also learn a number of advanced topics such as video mapping, interactive floors and walls, video morphing, networking, and using geometry shaders. You will learn everything you need to know in order to create your own projects; create projects of all levels, ranging from simple creative-code experiments, to big interactive systems consisting of a number of computers, depth cameras, and projectors.

Additional topics

In the chapter, we covered just a part of particle systems' ideas and methods. For further exploration of this field, we would suggest the following topics:

  • See the great introduction on particle systems' physics (for Processing language) in The Nature of Code, Daniel Shiffman, at

  • Look at the Box2D physics library, which can be used for modeling elastic bounces between particles. Actually, this is a universal and an extremely popular 2D physics library, which can be useful in various projects even not related to particles. To use the library in openFrameworks, you can use the ofxBox2d addon by Vanderlin available at

  • Play with the marching cubes algorithm, which provides the other way for rendering particles, not as sprites but as polygonal volumes in 3D space. Such a method of particles' visualization is called metaballs, and it can be a fruitful source of interesting visual effects. (See the Additional topics...
