Who This Book Is For

If you are a programmer, visual artist, or designer with experience in creative coding, and want to use openFrameworks to create fun, stunning, and interactive applications, this is the book for you. Basic knowledge of programming languages, such as C++, Java, Python, or JavaScript, will be enough to proceed with the book.

What You Will Learn

• Install openFrameworks and create a new project
• Generate 2D and 3D graphics
• Mix images and videos and process them with shaders
• Add GUI controls and adjust them from external devices and apps using the OSC protocol
• Control parameters with a timer, Perlin noise, and sound and text files
• Use the Arduino to control your application
• Build a video synthesizer project
• Run your project on iOS, Android, and Raspberry Pi devices

In Detail

openFrameworks is a cross-platform programming toolkit and library to perform creative coding in C++. It contains all you need to efficiently implement real-time tasks, such as generating 2D and 3D graphics, processing video and sound, and using networking.

openFrameworks Essentials is a guide that can be used for learning and using openFrameworks to develop creative and artistic real-time applications. It is a fast-paced tutorial that begins with installing openFrameworks, and then takes a step-by-step approach towards using openFrameworks to build a video synthesizer project. We will investigate and implement features such as 2D and 3D graphics, GUI, shaders, reaction on sound, the OSC networking protocol, and the Arduino.

This book will empower you with the practical skills required to build creative apps and projects using openFrameworks.
