New capabilities in web browser JavaScript implementations including networking, improved graphics performance, and improved speed allow the implementation of Networked Virtual Environments (NVEs) inside the web browser. An NVE can be written in JavaScript, which enables deployment in the enterprise entirely from a web server without the use of bro...

In a net-centric environment, data, tools and people operate in a distributed network. We explore a generic, flexible, scalable, usable and intelligent web services architecture framework that enables sharing and integration of web services on the fly. As an example application, the envisioned Web Service Architecture Intelligent Framework (WSAIF)...

The Distributed Interactive Simulation (DIS) IEEE-1278.1 standard is used in many military simulations. The binary data format for DIS does not lend itself to use in emerging web services standards or data analysis and storage tools because the data format is not recognized by most general purpose data manipulation tools. We examine an alternate XM...

Distributed, real-time virtual environment (VE) architectures have traditionally been driven by quality of service (QOS) considerations, with little or no concern paid to security issues. With recent advancements in functionality, computing power and network bandwidth it has become practical to use VEs in sensitive areas such as product development...

If large-scale shared virtual worlds are to be established on the Internet, they must be based on technologies that allow them to adapt, scale, and evolve continuously---that is, without their being taken offline. In the course of designing NPSNET-V, an architecture intended to satisfy these criteria through componentbased dynamic extensibility, th...

The availability of inexpensive and powerful graphics cards as well as fast Internet connections make Networked Virtual Environments viable for millions of users and many new applications. It is therefore necessary to cope with the growing heterogeneity ...

At the Naval Postgraduate School (NPS) we, like others in the collaborative VE community, have extolled the virtues of persistent online virtual worlds for years. We previously addressed the infrastructure requirements of a large-scale, persistent online virtual world: runtime extensibility of both content and applications; scalability in world com...
