Increasingly, the computer graphics applications we use at work and play are exploiting and supporting real-time interaction in networking. Our course will introduce attendees to recent advances and best practice in the networking of graphics applications. We take a broad view of networked graphics, including the domains of network games, virtual reality and networked simulations. We start by noting why networked graphics applications have different requirements on the network as compared to “normal” applications. We then pay particular attention to issues of latency, bandwidth and scalability. The course is very timely; networking has been acknowledged in SIGGRAPH’s own materials as important for application domains ranging from games through training to visualisation. Most existing tutorial material was developed before the age of commonly available broadband and wireless technologies. These technologies have enabled different types of environment and technology strategies, from massive social worlds with thousands of users through to fast-paced games on peer-to-peer networks. Furthermore, with the resurgence of thin-client systems such as OnLive, the field is ripe for further innovation.

Level
Beginner

Intended Audience
Developers, programmers and analysts interested in networked graphics and its application in games and simulation. Researchers from a range of disciplines interested in the latest state of the art and areas for future development. Students interested in learning more about key technologies behind games, virtual reality and simulations.

Prerequisites
Some basic experience of Internet technologies (e.g. protocols and services). We will assume some basic knowledge of computer graphics (e.g. coordinate systems and types of 3D models used in real-time systems).

Presenter(s)
Anthony Steed is a Professor at University College London. His research interests are in collaborative virtual environments, immersive virtual reality, interaction, and human animation. Together with Manuel Oliveira, he wrote the book Networked Graphics: Building Networked Virtual Environments and Networked Games. For part of the academic year 2006 to 2007 he was on sabbatical to Electronic Arts in Guildford. He is also the director of the United Kingdom's Engineering Doctorate Centre in Virtual Environments, Imaging, and Visualization.
