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.

Linking an addon to an existing project

If you are working on the project and suddenly realize that you need to link an addon, don't worry. You can do it at any time by performing the following steps:

  1. If the addon is not installed in the addons folder yet, download and install it by following instructions from the Installing a non-core addon section.

  2. Add all the .h, .cpp, and .lib or .a files from the src and lib folders of the addon to your development environment's project.

  3. If necessary, add paths to the addon's folder and all its subfolders into the project's settings.


Most addons contain the file install.xml in their folders. This file describes the exact information about linking an addon for each platform. By the way, Project Generator uses this information to link an addon. You can read this file and follow its information to link the addon yourself.

Note, for adding paths to addon's folder in openFrameworks's project for Linux, you need to just add line with the addon's name in addons.make file in the project's folder. See details at
