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 TCP protocol for streaming images

TCP is the basis for all the Internet protocols, for example, HTTP. This is an error-checking protocol, which guarantees obtaining valid data and notifying errors. This makes it appropriate for sending big volumes of data from computers, not only in your local network, but also around the world.

For working with TCP in openFrameworks, you need to use the ofxNetwork addon.


We suggest that the first time, you should try TCP with openFrameworks examples: networkTcpServerExample and networkTcpClientExample, located in openFrameworks's folder examples/addons. Run both of them on one PC, and then activate the window of networkTcpClientExample and press some keys. You will see that the keys will be sent to networkTcpServerExample and printed on its screen.

For linking the ofxNetwork addon, there are three options similar to the ofxOsc addon. Check the beginning of the Using OSC protocol section for details.

The scheme of working with TCP is based on the client...
