Chapter 1, openFrameworks Basics, covers installing openFrameworks, the structure of openFrameworks projects, and creating the pendulum-simulation project.

Chapter 2, Drawing in 2D, explains the basics of two-dimensional graphics, including drawing geometric primitives, working with colors and drawing in the offscreen buffer. It also contains a generative art example of using numerical instability for drawing.

Chapter 3, Building a Simple Particle System, teaches the basics of particle system modeling and drawing. By the end of this chapter, you will build a fully featured project that can be used as a sketch for further experiments with particles.

Chapter 4, Images and Textures, covers the principles of working with images, including loading images from file; rendering it on the screen with different sizes, color, and transparency; creating new images; and modifying existing images. It also touches the basics of image warping and video mapping.

Chapter 5, Working with Videos, covers basic and advanced topics on playing, layering, and processing videos, including playing video files, processing live video grabbed from a camera, and working with image sequences. This chapter contains an implementation of the slit-scan effect and a simple video synthesizer, which uses a screen-to-camera feedback loop to create vivid effects on prerecorded videos.

Chapter 6, Working with Sounds, explains how to play sound samples, synthesize new sounds, and get sounds from the microphone. It includes the project wherein we generate music using bouncing-ball simulation, the PWM synthesizer, and the image-to-sound transcoding. Finally, it teaches us how to use spectrum analysis for creating an audio-reactive visual project.

Chapter 7, Drawing in 3D, covers representing, modifying, and drawing 3D objects. It includes examples of drawing a sphere-shaped cloud of triangles, an oscillating surface, and a twisting 3D knot.

Chapter 8, Using Shaders, explains how to use fragment, vertex, and geometry shaders for creating 2D video effects and 3D object deformations.

Chapter 9, Computer Vision with OpenCV, teaches the basics of computer vision using the OpenCV library. It explains how to perform filtering and correct perspective distortions in images and how to look for motion areas and detect bright objects in the videos. It includes an advanced example of using optical flow for video morphing.

Chapter 10, Using Depth Cameras, covers using depth cameras in openFrameworks projects using the ofxOpenNI addon. It includes an example of the projector-camera interactive system, which lets us draw abstract images on the wall. The example can be used as a sketch for creating interactive walls, tables, and floors.

Chapter 11, Networking, covers how to use OSC and TCP protocols in your openFrameworks projects for creating distributed projects that run on several computers. It includes an image-streaming example.

Appendix A, Working with Addons, teaches the basic principles of addons, explains how to link addons to your projects, and discusses some of the most useful addons.

Appendix B, Perlin Noise, explains the principles of using Perlin noise, which is employed in many of the examples in the book.
