The Study Of Visual Simulation Technology Based On HLA

Visual Simulation Technology is the main investigative content of Distributed Interactive Simulation Technology and Virtual Reality Technology,and an important embranchment of Modern Simulation Technology.Visual Simulation Technology is propitious to shorten the period of experiment,improve the quality of development and save the outlay of scientific research. Visual Simulation Technology has been used in many fields. With the development of Computer Simulation Technology, single Visual Simulation System can not satisfy the need of Complex Simulation System. The Distributed Interactive Simulation based on HLA is the future orientation of the Simulation Technology. So, to study the Visual Simulation Technology based on HLA has an important meaning of engineering and practicality.This paper which aims at the pivotal problems of real time and authenticity in Visual Simulation Technology, study the principle and arithmetic of the pivotal technologies. The Collision Detection Technology is emphasized. Convex polyhedron collision detection arithmetic based on SRGA is put forward. HLA distributed interactive simulation system is accomplished base on Multigen Creator and Vega Prime, and an example is given. The material work as follows:1. The principle and arithmetic of Texture Mapping Technology,Hiding Technology,Levels of Detail Technology and Collision Detection Technology are studyed. Studying these problems is propitious to establish a Visual Simulation System with real time and authenticity.2.Using convex hull to show convex polyhedron, the problem of accounting the distance between two convex polyhedrons is summed up a non-linear programming problem with restrict conditions. Use genetic algorithms combined with SR to solve the problem.3. Study the modeling technology of Multigen Creator and the Visual Simulation Technology of Vega Prime. Multi-channel technology based on Vega Prime is emphasized .These problems are propitious to establish a Visual Simulation System with real time.4. Under the circumstance of HLA,study the exploitation of Visual Simulation Federate. Combined with VC++, using Multigen Creator to modeling and Vega Prime to drive the scene, design and accomplish a visual multi-channel naval vessel simulation system.
