Real Time Dynamic Interactive Visual Simulation

Simulation is a synthetic technique. There is much excellence with it,credibility,no destruction;repeatability,safety,economy,no bound with in climate,locale,and space and tight with life of human being. RTDIVS (Real Time Dynamical Interactive Visual Simulation) is the kernel of ADS (Advance Distributed Simulation). It is the main ideal of VP (Virtual Prototypes) and a new domain of information anthropomorphization representation. So it does support the development of Defense,industry and manufacture,transportation,engineering preview,city planning,aviation spaceflight,training,education,medicine,real estate,business and entertainment etc. Therefore,experts and scholars of the scientific world give thire much attention to the RTDIVS results. The Department of Defense of U.S. used the RTDIVS technique to deduce new campaign concept firstly. Especially,in 1996,America Defense Modeling & Simulation Office analyzed the environment of Distribute Interactive Simulation deeply and put forward High Level Architecture,Federation,Federates,and Federation Execution. These concepts are solid base to support RTDIVS implement. After middle of 1990's,Visual Simulation Entities in our country seemed that bamboo shoots after a spring rain. [172]-[200]Results of Modeling & Simulation of sight and Collaborative Virtual Prototyping research emerge endlessly.In this thesis,the author 100ks back the history of simulation,analyzes essential character of RTDIVS information reflecting. It is suggested that to build simulation system is an aspect of Reflecting Theory of Information Model (RTIM) with people as information host;the author expatiates to the ideal of simulation foundation by theory. It is presented that behavior of simulation is abstracting and synthetic cognizing to the investigating object. Simulation System must be constructed as a monomorphism of investigating object with comparability of mathematics and geometry. Reflecting Theory of Information Model presented by the author is used as guidance of ideal. To the primary contradiction of RTDIVS,limited bandwidth of network and real time transmitting parameter of relative to move sight,the modeling theory,and the method of development and encoding theory are researched deeply. Interactive platform of automation vectorization of 2-D image and remarking is set up inthis way. The control mechanism of 3-D visual object of agent is discussed,and VF-SDM,Visual Federation Synthetic Development Method is presented. It is a method of spiral,gradual,independence and synchronization. By the VF-SDM,visual simulation system is decomposed and assorts with Object Model,Simulation Model,Visual Federation Model,Move Controlling Model,and Display Synchronization Model. The author designed a grammar of visual federation context and a Turing conversion mechanism,and concept composes of graph language. At last,the VFRTI,Visual Federation Run Time Infrastructure,is setup on the HLA. The process of information is emphasized in author's RTIM. The general ideal of RTIM is used into RTDIVS. It supports to establish the VF-SDM,practice,and combine simulation with information anthropomorphization representation. It inaugurates a new field with visual simulation developing. 'There are 10 chapters hi this thesis. In Chapter 1,the history of simulation is 100ked back,the actuality status about Computer Simulation is given delineation,finally the concept of RTDIVS is put forward. In Chapter 2,the base of computer simulation is demonstrated with theory. It is presented that behavior of simulation is abstracting and synthetic cognizing to the investigating object,and simulation system is a monomorphism of investigating objects and is based on analogism. In Chapter 3,some abstract tools are summarized;logic algebra,relative algebra,type algebra,differential equation,scatter representation and Turing computing model. In Chapter 4,a lot important approaches of software development are analyzed,and then VF-SDM (Visual Federation & Synthetical Development Method) is presented based on it. The detail...
