....the same experience. Distributed Virtual Environments (DVE) are seeing increased use for a wide range of applications, such as military battlefield simulations, education and training systems, virtual teleconferencing, collaborative modeling and engineering, and multi user networked video games [45, 50, 42, 11, 57, 26]. The trend of faster processors, more powerful computer graphics hardware and software packages, and higher capacity networks makes it possible for large scale distributed virtual environment to contain well over 100,000 dynamic entities [59] 1.3 Database Model of DVE One of the critical ....

....will be visible to all other peers. In client server configuration, communication servers or name servers are used to either multicast the state update messages to all subscribers, or establish connections between the process that modifies a state variable and the processes that consume it. DIVE [11] adopts a peer to peer distribution. It utilizes the ISIS communication library [9] to provide reliable, causally and totally ordered delivery of communication messages. The ISIS protocol uses an ownership mechanism to provide the consistency management of state information. If a peer wants to ....

....with a variety of organizations and institutions increasingly finding novel and innovative uses for this technology. These uses encompass the fields of design, entertainment, medicine and engineering [2,4,10,14] Applications of CVE technology have evolved into successful architectures like DIVE [6], MASSIVE [9] COVEN [14] MAVERIK [12] DEVA [15] and DeepMatrix [17] This promising new technology will clearly benefit from further evolution through its application to challenging problem domains. This paper presents the design and development of Collaborative Urban Planner (CUP) a prototype ....

....between di#erent processes. Specific memory locations can be marked as shared, and data written into these locations will be transmitted to other processes. A receiver has to explicitly receive the data and apply it to it s local database. All communication is point to point. 2.2. 3 DIVE DIVE s[14] distribution mechanism is based on ISIS, a fault tolerant communication system from Cornell University. DIVE supports multi user applications by replicating all objects in the scene graph. Objects have a standard form which comprises a simple geometry plus an optional eventdriven finite state ....

Q Pit, VR Vibe, VR Mapper These prototypes, developed within the DIVE system [Carl93], show three different approaches to abstract data visualization systems. All of them are in fact PITS (Populated Information Terrains) allowing to share the data with other users and be aware of their actions. Q Pit follows the first of the four approaches just mentioned and uses an attribute ....

....of another user, e g by opening a new window on the other s view. In an immersive setting this would require a full context switch, or an inset window if display resolution allows this. 4. Implementation VR VIBE is implemented in version 3. 1 of the DIVE multi user virtual environment system [5, 14]. The default behaviour of DIVE is to distribute all objects in a given world (dataset) to all processes connected to that world, i e within the same process group. Any connected process can access and modify the data and updates are multicast to all other processes within the same process ....

....by including more of the factors thought to underlie presence (detailed in Section 2) in the high presence VE than in the low presence VE, and purposefully disrupting these factors in the low presence VE. The DIVE software developed by the Swedish Institute of Computer Science (SICS) [2][1] was used to create the two CVEs. Participants were divided into six groups of three members. These groups were arbitrarily assigned to either the high or low presence environments, and as far as possible the presence factors listed above were kept constant within each group. Group members ....

....described above, we used 2 D animations of facial expressions. We hope to extend the system to animate 3 D facial models, such as those developed by Waters [13] 2. Integration with a Virtual Environment: The entire animation system could be integrated with a virtual environment, such as DIVE [4, 3], in order to enhance the collaborative aspects of the interaction. User experiments may then be performed to test the impact of facial animation on immersion and presence. In addition, commercial systems are now appearing that track facial features reliably without requiring markers. If we can ....

....Schiano et al. [28] conducted similar experiments on a simple robot face and showed good recognition rates. We hope to conduct similar tests. Our major goal is to combine the 3 D model with a full body avatar and integrate the system with a collaborative virtual environment, such as DIVE [5, 6]. We will then conduct a series of experiments to test the e#ects of real time facial animation on immersion and virtual presence . 9 CONCLUSION AND FUTURE WORK We have presented a system for real time facial expression tracking and animation. Our system uses relatively low cost equipment and a ....

....On the other hand in open information spaces there are important reasons not to distribute all geometry information without control, because security, bandwidth and performance requirements must be taken into account. Examples for local 3D visualization with data replication are presented in [1], 5] and [8] Many of these systems are used to support cooperation with distributed 3D visualization. Alternatively, remote 3D visualization as a service can be used to let users interactively visualize 3D scenes. On the clientsideof a network connection a visualization application reads the ....

These projects are mostly 8 stand alone systems that have explored basic DVE concepts of object model interchange, networking performance, and underlying application level ....

....backbone or MBONE. The MBONE system uses tunneling ; it wraps the IP packets destined for a multicast address inside another IP packet, which travels through the regular Internet from one MBONE subnet to another [6] Many others utilized multicasting protocols such as NPSNET [19] and DIVE [5]. 2 Specification Paradigm DLoVe is a specification paradigm that allows programmers to easily define and implement Virtual Reality programs in the context of a one way constraint engine. In addition, it provides a framework where computationally expensive tasks can be performed in parallel in a ....
