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.

Using Open Sound Control with mobile devices


Open Sound Control (http://opensoundcontrol.org) is a communication standard among computers, audio synthesizers, and multimedia devices within a computer network. Pure Data supports the Open Sound Control (OSC) protocol through a library mrpeach packaged within the pd-extended software.

With the gaining popularity of multi-touch technology, it is common to use the versatile multi-touch devices to control the operation of the host software, in applications such as audio-visual performance, and multimedia display. Information exchange among the multi-touch devices use another protocol, TUIO (http://www.tuio.org), and the one that is based on the OSC. For example, we can use an iPhone to control the animation within a GEM window in a host computer running Pure Data. This is the method that we are going to explore.

The first thing is to download a free iPhone app that supports TUIO. One of the choices is the TUIOpad (http://code.google.com/p/tuiopad...
