Visual Simulation Technique Based On Multigen & Vega Applies In Emergency

Multigen creator and Vega are very powerful visual simulation softwares, which using computer graphics and images technology, according to the target of simulation to construct the 3D model of the object to reproduce the reality environment, which can achieve vivid simulating effect and access mutual between the user and the environment. To ensure that people can disperse safely in the emergency, during the design period of optimizating evacuation procedures' system design program, we should strengthen scientific management, formulate plans which have quantitative indicators and easily to be operated, so that in case of an emergency, we can facilitate timely and have effective organization. Simulate the emergency in different kinds of scences using visual simulation technology so that it can reflect the overall architecture's safety performance of emergency evacuation well .The operation of architecture equipment is the impotant constituent parts of emergency, it has great impact on evacuation procedures, but the exesting computer simulations of the emergency involve little to that . In this paper,This paper, firstly, summarizes the visual simulation and architecture emergency's research actuality, and introduce the multigen creator &Vega's features and functions, which is the tools of visual simulation, then give a detailed account of three dimensions visual simulation's critical technology, in the process of building up the visual scences, we combine with the multigen creator &Vega's respective advantages in modeling, and discuss the problems met in the modeling process using the two tools of visual simulation and the method to resolve the problems. In the base of building up the emergency's visual scences,secondary development using mfcvega simulate the fire alarm system in vc++ environment, including the controlling of the state of elevate, kalamein door, exhaust fan, emergency directional lights. At last some special effects in the emergency are brought about, the fire sprinkler'simulation is emphasized, including the water-cannon of numerical control's brief process of spraying water, in nowadays, it is a advanced fire-fighting device, the nature environment is also a part of emergency, which can add the virsual scence's sense of reality and also has some effect to the emergency, so that we introduce the method to simulate some kinds of nature environment. At last, after summarizing the whole paper, limitations in the research of this paper are analyzed, the trend of research work in the future is brought forward.
