Using a Physical Metaphor to Scale Up Communication in Virtual Worlds


Book Description

This dissertation argues that application-level messaging in virtual worlds must have five properties to enable scalability while avoiding the undesirable limitations of existing systems: recipient selection, minimum quality of service, graceful degradation, fine-grained multiplexing and high utilization. To address these issues, the Sirikata system architecture, a new virtual world back-end system, was developed that achieves these five properties. Sirikata's key insight is to leverage the geometric nature of virtual worlds by applying a physical metaphor to communication. Object communication follows an inverse square law, behaving similarly to point-source radio transmitters and receivers. The theoretical scalability results are proven, and some valid approximations are investigated. Then an implementation of a message forwarder that supports a large number of objects and prioritizes traffic using such an inverse square falloff is introduced. Evaluations of Sirikata show that it satisfies the stated requirements, performs better than current virtual worlds, and can closely follow the real-world radio communication analogy. Finally, a range of sample application demonstrates the effectiveness of this approach. Each sample application is coded in the world and studied when the system is loaded.




Scientific Engineering for Distributed Java Applications


Book Description

FIDJI 2002 was an international forum for researchers and practitioners in- rested in the advances in, and applications of, software engineering for distri- ted application development. Concerning the technologies, the workshop focused on “Java-related” technologies. It was an opportunity to present and observe the latest research, results, and ideas in these areas. All papers submitted to this workshop were reviewed by at least two members of the International Program Committee. Acceptance was based primarily on the originality and contribution. We selected for these postworkshop proceedings 16 papers amongst 33 submitted, two tutorials, and two keynotes. FIDJI 2002 was aimed at promoting a scienti?c approach to software engin- ring. The scope of the workshop included the following topics: – design of distributed Java applications – Java-related technologies – software and system architecture engineering and development methodo- gies – development methodologies for UML – development methodologies for reliable distributed systems – component-based development methodologies – management of evolutions/iterations in the analysis, design, implementation, and test phases – dependability support during system lifecycle – managing inconsistencies during application development – atomicity and exception handling in system development – software architectures, frameworks, and design patterns for developing d- tributed systems – integration of formal techniques in the development process – formal analysis and grounding of modeling notation and techniques (e. g.




Distributed Virtual Worlds


Book Description

Recently, with the success of Java and the existence of different interfaces be tween VRML and Java, it became possible to implement three-dimensional internet applications on standard VRML browsers (Plugins) using Java. With the widespread use of VRML-Browsers, e.g., as part of the Netscape Com municator and Microsoft's Internet Explorerstandard distributions, everyone connected to the internet via a PC ( and some other platforms) can directly enter a virtual world without installing a new kind of software. The VRML technology offers the basis for new forms of customer services, e.g., interactive three-dimensional product configuration, spare part ordering, or customer training. Also this technology can be used for CSCW in intranets. This book has a theoretical and a practical part. The theoretical part is intended more for teachers and researchers, while the practical part is in tended for web designers, programmers and students, who want to have both a hands-on approach to implementing Web 3D applications and a technically detailed overview of existing solutions for specific problems in this area.

Virtual Worlds


Book Description

Virtual Worlds 2000 is the second in a series of international scientific conferences on virtual worlds held at the International Institute of Multimedia in Paris La Défense (Pôle Universitaire Léonard de Vinci). The term "virtual worlds" generally refers to virtual reality applications or experi ences. We extend the use of these terms to describe experiments that deal with the idea of synthesizing digital worlds on computers. Thus, virtual worlds could be de fined as the study of computer programs that implement digital worlds. Constructing such complex artificial worlds seems to be extremely difficult to do in any sort of complete and realistic manner. Such a new discipline must benefit from a large amount of work in various fields: virtual reality and advanced computer graphics, artificial life and evolutionary computation, simulation of physical systems, and more. Whereas virtual reality has largely concerned itself with the design of 3D immersive graphical spaces, and artificial life with the simulation of living organisms, the field of virtual worlds, is concerned with the synthesis of digital universes considered as wholes, with their own "physical" and "biological" laws.
