Description
Networked virtual environments (net-VEs) offer a three-dimensional, virtual "space" in which users around the world can interact in real-time. Net-VE applications--already in use by the military and aerospace and entertainment industries--are used to enhance engineering design, scientific research, and electronic commerce. This emerging, rapidly proliferating field is propelled by globalization and increasingly sophisticated networking capabilities. Written by two of the field's leading pioneers, this book represents seminal work on networked virtual environments. Offering a comprehensive examination of net-VEs, the text covers the underlying technologies and provides a step-by-step roadmap for designing and building interactive 3D virtual environments. In particular, the authors focus on strategies for overcoming limitations that can impede real-time interactive system development and describe numerous practical techniques for creating successful, real-world net-VE applications.You will find in-depth coverage of important topics, such as: *Basic challenges in net-VE design *Relevant networking principles and Internet communication protocols *How to organize the communications infrastructure *How to manage dynamic shared states *System design for real-time, multiuser interaction *How to ensure real-time response and scalability by managing limited bandwidth and computational resources *Emerging techniques and standards for deploying net-VEs over the Internet Moving beyond the state of the art, Networked Virtual Environments points to future developments that will make net-VEs a pervasive form of professional and personal telecommunications.

Persons
Sandeep Singhal is CTO of ReefEdge, Inc.--a wireless applications and infrastructure company based in Fort Lee, New Jersey. He was formerly Chief Architect and a Senior Technical Staff Member for IBM's Pervasive Computing Division, where he was responsible for product design to support network connectivity from a broad range of sub-PC devices to Web servers and application infrastructure. He previously worked as a Research Staff Member in IBM's T. J. Watson Research Center and as a Software Engineer for the National Aeronautics and Space Administration (NASA). He is also an adjunct assistant professor on the graduate faculty at North Carolina State University in Raleigh.
Sandeep's interests include network protocol design for large-scale collaborative and real-time systems, object-oriented software engineering, and network computing for pervasive computing devices. His credits include dozens of publications, including Networked Virtual Environments (Addison-Wesley, 1999), and ten issued patents. He served for the Defense Advanced Research Projects Agency (DARPA) on an advisory board defining a long-term networked virtual environment research agenda and participated in a National Research Council effort to link military and entertainment applications of simulation technology. Sandeep also played a key role in defining and implementing the Defense Department's High Level Architecture (HLA) for distributed simulation.
Sandeep has participated in the WAP Forum since February of 1998. He currently chairs the User Agent Profile drafting committee and the Architectural Consistency Group at the WAP Forum. He is a member of the W3C Mobile Access Interest Group and is actively working toward converging WAP technologies with the larger Web.
Sandeep holds M.S. and Ph.D degrees in computer science from Stanford University, as well as B.S. degrees in computer science and in mathematical sciences and a B.A. in mathematics from Johns Hopkins University.
Michael Zyda is a professor in the Department of Computer Science at the Naval Postgraduate School in Monterey, California, where he performs research on net-VEs. He was a member of the National Research Council's Committee on Virtual Reality Research and Development, and also has served as Chair of the National Research Council Committee on Modeling and Simulation: Linking Entertainment and Defense.
