However, many particle system applications require fast interactive animations. For example, simulation of physically realistic complex dust behaviors is very useful in training, education, art, advertising, and entertainment. There are no published models for real-time simulation of dust behavior generated by a traveling vehicle. In this paper we use particle systems, computational fluid dynamics, and behavioral simulation techniques to simulate dust behavior in real time. First, we analyze the forces and factors that affect dust generation and the behavior after dust particles are generated. Then, we construct physically-based empirical models to generate dust particles and control the behavior accordingly. We further simplify the numerical calculations by dividing dust behavior into three stages, and establishing simplified particle system models for each stage. We employ motion blur, particle blending, texture mapping, and other computer graphics techniques to achieve the final results. Our contributions include constructing physically-based empirical models to generate dust behavior and achieving simulation of the behavior in real time.","PeriodicalId":129736,"journal":{"name":"Proceedings 3rd IEEE International Workshop on Distributed Interactive Simulation and Real-Time Applications","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127427846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similar to real-life physical team rooms, which provide a permanent shared space used by a work group, TEAMWORKPLACE, the virtual space presented in the paper provides a virtual meeting room, i.e. a place to store, retrieve and present multimedia content (documents), to design and construct cooperatively, to brainstorm, to negotiate and make decisions, to run shared applications, to browse enterprise data, or to acquire, formalise and exchange enterprise knowledge. Since physical team rooms rely on the physical proximity of the team members and their easy access to the common work space, this access breaks down when groups are geographically dislocated. For such teams, TEAMWORKPLACE provides the electronic equivalent of a physical team room transcending distance, time zones, and organisational boundaries. TEAMWORKPLACE is based essentially on two open technologies: the virtual reality modelling language (VRML) and Java. A Java-enabled Web browser, together with a VRML plug-in is the only requirement for the execution of TEAMWORKPLACE on current consumer hardware.","PeriodicalId":129736,"journal":{"name":"Proceedings 3rd IEEE International Workshop on Distributed Interactive Simulation and Real-Time Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128914161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The actor model centers on non-overkilling concurrency and customizable constraint-directed scheduling. A distributed multimedia system consists of a collection of actors interacting with one another to fulfil a common goal, e.g., interactive videoconference, video recording on-demand, etc. Timing synchronization rests on reflective actors (QoSsynchronizers) which filter actor messages and schedule them according to application-dependent QoS parameters. Requirements of a multimedia system can be formalized by Time Stream Petri Nets. In order to support QoS constraints analysis and validation, media actors are then prototyped under simulation by exploiting the flexibility of the adopted actor model to operate transparently under real or virtual time. The transition from the modeling, to analysis, down through to the implementation stages is therefore seamless. The paper describes the application of the methodology to the development of a lip-sync filter for live or on-demand multimedia sessions and reports some collected experimental results.","PeriodicalId":129736,"journal":{"name":"Proceedings 3rd IEEE International Workshop on Distributed Interactive Simulation and Real-Time Applications","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115135268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By enforcing strict conformance to the DIS and/or HLA, the Defense Modeling and Simulation Office (DMSO) has so far been able to \"mix-and-match\" different simulation models and frameworks to satisfy the military's simulation needs. However, by linking different legacy simulations (simulations previously designed to operate independently) together, the simulation now has to correctly handle multiple levels of detail in the interacting simulation entities. In addition, a given entity itself can be represented in different ways each with a different level of detail (also referred to as resolution or fidelity). A natural question to ask in this situation is why does the model require different resolutions? Why isn't one level of resolution sufficient to address all the needs of the simulation? There is no simple answer to this question. Depending on the model, what it is used for, and what it is interacting with, it may require several different resolutions. One justification for the need for different resolutions is the way humans think and comprehend information. In general, humans think and reason at different levels of detail and therefore require models to reflect their chosen resolutions. By embedding their knowledge into simulation models, simulation designers try and build a virtual world that mimics the real world. We survey and review previous attempts at multi-resolution modeling and discuss its implications for the DIS, HLA, and parallel discrete-event simulation (PDES) communities.","PeriodicalId":129736,"journal":{"name":"Proceedings 3rd IEEE International Workshop on Distributed Interactive Simulation and Real-Time Applications","volume":"21 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121016579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
