“…The Environment is built using the Ygdrasil (Pape et al 2003) virtual reality authoring system, C++, and Python. Real-time dynamic behaviors and interaction make use of an event-based structure; messages are passed between nodes in response to events.…”

The Trail is an interactive drama running on an immersive VR system. Imagine Tarkovsky's Stalker, crossed with Alice Through the Looking Glass, crossed with Monty Python and the Holy Grail. Now imagine embarking on a guided journey through this warped yet familiar landscape. Your guides are two intelligent agents, Patofil and Filopat. We consider a virtual reality drama to be a scripted play in which the computational agents are actors who have copies of the script, and one human audience member has been drafted to be a participant, but doesn't have a copy of the script. The computational actors must improvise reactions to the human participant's actions, but keep the play moving along in as close agreement to the script as possible. The goal is to provide the human participant with a specific emotional experience.

“…Application centric frameworks (e.g.DIVERSE, Ygdrasil) provide a component-based development and deployment platform (Kelso, Satterfield, Arsenault, Ketchan, andKriz 2003, Pape, Anstey, Dolinsky, andDambik 2003). In these frameworks, components developed as dynamic objects are dynamically integrated in the application at the deployment time.…”

Service-Oriented Architecture (SOA) is an application framework used for creating complex enterprise systems by integrating distributed services. The SOA standards are primarily focused on the service composability and data interoperability. Because of the featured capabilities of SOA, it is also used in distributed simulations. However, SOA has its limitations in terms of the performance of real-time message exchanging. In order to address the disadvantages and improve the application performance, we propose a framework that combines the streaming technology and SOA. The proposed framework is used for constructing multi-user Virtual Environment (VE) applications by integrating the application content from distributed services. The additional streaming channels applied to SOA enable the services to actively propagate the real-time messages. The VE applications constructed using the framework have better performance. However, due to the distributed architecture of SOA and the heavy payload of message exchange in the framework, the application performance needs to be evaluated. We describe the metrics used to evaluate the performance and present the evaluation results. Based on the interaction latency we collected from the experiments, we discuss the categories of applications that can fit well in our framework.

“…In order to keep the consistency, we introduce the shared scene graph for creating global consistent view for all the connected users. The shared scene graph is inspired by [Pape et al 2003]. A global shared scene graph is constructed from the local scene graphs provided by the participating component services.…”

Distributed Virtual Environments (DVEs) are distributed, simulated virtual worlds where users gather and interact within a shared space. Web-based DVE applications are attracting more and more attention. However, building DVE applications requires a significant effort, even with the modern development tools. In this paper we propose a component-based and a service-based framework for constructing DVE applications from coarse-grained components. This component-based and service-oriented architecture provides a great flexibility for building complex DVE applications. Based on the developed terminology and profile, the framework provides a high level description language for specifying user interaction tasks. The DVE developers can concentrate on the application design rather than worrying about the programming details. The framework also provides a runtime platform for coarse-grained components integration and a shared scene graph for coordinating the presentation for individual users.
