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.

Installing on Mac OS with Xcode

We will be using Mac OS X 10.8.4 and Xcode 4.6.3. The installation steps are as follows:

  1. Install Xcode by downloading it from the Mac App Store.

  2. Download the openFrameworks archive. Go to and download openFrameworks for Xcode. The downloaded ZIP file should be named like of_v0.8.0_osx_release. Unzip the downloaded file; it will be a folder containing openFrameworks. Move the folder to any location on your computer, for example, on the desktop.

  3. Let's compile and run some examples to verify openFrameworks is working correctly. Navigate to the examples/3d/pointCloudExample openFrameworks folder and open pointCloudExample.xcodeproj in Xcode.

  4. The project in Xcode contains several schemes for building openFrameworks and the example itself. For compiling your project, you need to select the example's scheme. Check it out. If the current scheme is openFrameworks, you will see the following button:

  5. Click on it on the left-hand side and select the example project, pointCloudExample:

  6. Press Command + B to compile the project.

  7. Press the Run button.

  8. Follow the steps 6, 8, and 9 from the Microsoft Visual Studio section. (Considering step 7, describing console window, the separate console window does not appear in Mac OS X, and all such information is printed in the Xcode console.)
