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.

Networking basics

Networking comprises a number of hardware and software technologies that provide data exchange among digital devices and even among applications inside a computer. The most popular network model today is called TCP/IP (Transmission Control Protocol/Internet Protocol). It works using wired (LAN—Local Area Network) or wireless (WLAN—Wireless LAN) connections. All the modern computers and mobile devices have support of TCP/IP.


Another networking technology is wireless ZigBee networks, widely used in physical computing projects. Connecting just two devices can be considered as the simplest network. Old but still popular technologies for wired connections are USB, serial port (RS-232), RS-485, and I2C (used for micro devices).

In this chapter, we will consider usage of TCP/IP for connecting several devices inside a local network. Local network is built and controlled by network router. A network router is a special network node working as a separate device or integrated within...
