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 this chapter we mainly considered representing and drawing 3D objects using openFrameworks. For further learning, we suggest studying the following topics:

  • Working with the ofLight class to control lights, that is, the type of light (spot light and point light), its position, light direction, and color parameters. See openFrameworks examples examples/3d/normalsExample and examples/3d/advanced3dExample.

  • Working with the ofCamera and ofEasyCam classes to control the camera, that is, the position of the observer of the 3D scene. The camera lets you move easily through the virtual 3D world and also change perspective parameters. See openFrameworks examples examples/3d/cameraRibbonExample and examples/3d/easyCamExample.

  • Using 3D model files with the .3ds and .dae extensions. You can load and draw such files as static or animated objects. Note that you can use 3D file models as a source of vertex data for further manipulation and processing. See openFrameworks examples examples...
