Multimedia Programming with Pure Data

By: Bryan, Wai-ching CHUNG

Overview of this book

Preparing interactive displays, creating computer games, and conducting audio-visual performance are now achievable without typing lines of code. With Pure Data, a graphical programming environment, creating interactive multimedia applications is just visually connecting graphical icons together. It is straightforward, intuitive, and effective. "Multimedia Programming with Pure Data" will show you how to create interactive multimedia applications. You will learn how to author various digital media, such as images, animations, audio, and videos together to form a coherent title. From simple to sophisticated interaction techniques, you will learn to apply these techniques in your practical multimedia projects. You start from making 2D and 3D computer graphics and proceed to animation, multimedia presentation, interface design, and more sophisticated computer vision applications with interactivity. With Pure Data and GEM, you will learn to produce animations with 2D digital imagery, 3D modelling, and particle systems. You can also design graphical interfaces, and use live video for motion tracking applications. Furthermore, you will learn Audio signal processing, which forms the key aspect to multimedia content creation. Last but not least, Network programming using Pure Data extension libraries explores applications to other portable devices.

Drawing basic 3D primitive shapes


All the 2D graphical shapes can work in the 3D environment. In addition, GEM provides a number of 3D primitives, such as cone, cube, cuboid, curve3d, cylinder, disk, sphere, teapot, torus, and tube. Let us learn it step-by-step by following a similar procedure.

Create an empty patch and save it with name gem003.pd in your folder. Put the gemwin object, create and destroy messages, and the toggle box for rendering.

We start from the simplest 3D object, cube. Put the gemhead and cube objects and connect them together. Similar to 2D shapes, we can also have the draw fill and draw line messages. Here is the patch and the resulting window. By using the draw line message, the 3D perspective projection of the cube is more obvious:

Here is the wire-frame rendering of the cube in the three-dimensional space:

Control for the cube object is simple. It has only one number inlet for its size. The next object is sphere. It has two parameters. One for the size and another...
