【摘要】 在构建面向全球的三维地形环境仿真平台时,如何降低各个模块之间的耦合度,提高软件的灵活性和复用性,是平台设计时需要考虑的一个关键问题。文中对三维地形环境仿真平台设计中存在的问题进行分析,介绍如何根据平台特点和设计要求选择适当的设计模式,并给出应用示例。实践表明,在三维地形环境仿真平台设计中应用设计模式,可以有效提高软件的可维护性和可扩展性。更多还原

【Abstract】 It is quite important to reduce the coupling between software modules when designing a 3D terrain environment simulation platform.On how to implement it,it just gives some of the answers.First,problems in system designing are analyzed in detail;second,several design patterns are introduced to solve these problems;at last,demos are given to show how to choose the right design patterns in system designing.It has been proved that design patterns can greatly improve the extensibility of a 3D terrain environment simulation platform.更多还原
