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.

Using OSC protocol

OSC is an extremely popular protocol for sending control commands and parameters between devices and applications. It is a protocol in which there is no confirmation of the data exchange success, that is, the sender doesn't know if the receiver received the data, and the receiver does not know if somebody sent something to it. As a result, data can be lost without any notification to the sender and the receiver. Though, in a local network such a situation is very rare and occurs only if you are using extremely fast frame rates for sending data.


OSC is a thin layer on the UDP protocol. For more information, read about UDP specification.

For using OSC capabilities in openFrameworks projects, you need to use the ofxOsc addon. This is a core addon included in openFrameworks distribution.


We suggest that the first time you try OSC, play with openFrameworks examples oscSenderExample and oscReceiveExample, located in openFrameworks's folder examples/addons. Run both of them...
