| In order to show the new characteristics of the product, to enlarge product cognition and support the sales, some new requirements have been proposed by some modern companies to the virtual-simulation system, including development of universal platform, low cost and high efficiency, etc, which have been becoming more and more important questions that need to be solved . The objective of this paper can be summarized as follows. Firstly, it is mainly about how to create the virtual dynamic environment and the display of the light and shade by using the tools of modeling 3D objects and making animation. Secondly, it will discuss how to use the low-cost and common virtual reality integrated tools which is popular in the world to complete the design of virtual operation and the method of developing the interface of the human-computer interaction. And the last, the cost, efficiency and the virtual simulation which are based on the professional level and practical value will be balanced.This paper analyzes the background of the virtual simulation system, and the factors of how to develop the virtual simulation system, and the technical features, research on the status quo at home and abroad and the research content of this project. It uses the "yong shi" off-road vehicle which is selected by Chinese army as the object of the industrial product, and the purpose is to design a display of a low-cost industrial product and a sort of simulation software based on 3D virtual reality technology. This paper summarizes the main work of the project and the process of its realization, such as project plan, requirement analysis, system design, software realization, and so on. And through detailed and complete system analysis, system design and system implementation steps, it demonstrates the application of software engineering in developing the project of the virtual reality simulation system, and discusses the relative difficulties and their solutions. |
