From coarse-grained components to DVE applications
Xiaoyu Zhang, Denis Gračanin · 2007
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.
