大型引水工程施工三维可视化仿真系统研究 总被引:3,自引:0,他引:3
为了直观、逼真地描述大型引水工程各环节之间复杂的动态时空逻辑关系,提出了大型引水工程三维可视化图形仿真系统。首先,对引水工程三维可视化图形仿真系统进行系统分析,确定系统的开发模式,然后采集数据并进行了仿真计算,再将所得数据以数据库的形式保存并对数据库进行加工处理,将空间数据(矢量数据、形体数据等)和各种属性信息集成在一起,在这些数据库的基础上建立引水工程三维可视化仿真模型及模型库,以方便对模型进行高效的管理,开发了一个能科学、直观、逼真的表现大型引水工程施工的三维可视化图形仿真系统,为工程施工管理决策提供依据。 相似文献

水下地形的构建与可视化 总被引:2,自引:2,他引:0
与陆地地形建模相比,水下地形的多分辨率建模是一个逆向的过程,它通过较为少量但非常有价值的数据来建立水下地形的拓扑结构。本文提出了一种对地形原始三角边的参数曲线描述方法,在此基础上根据对原始三角形的兴趣值通过分形的方法进行细化,研究实现了不同细化程度的相邻三角形公共边上的无缝连接,并开发实现了基于OpenGL的水下地形可视化应用系统。 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献

This paper presents an outline of an Oriental systems methodology: the Wuli Shili Renli approach (WSR). The basic theme of WSR contends that wuli (regularities in objective existence), shili (ways of seeing and doing), and renli (patterns underlying human relations) constitute a differentiated whole that conditions systems projects. WSR suggests that we should design and employ appropriate methods to address and tackle wuli shili and renli elements in a theoretically informed and systemic way. The background, philosophy, process, principles, and some practical applications of the methodology are preliminarily outlined. 相似文献
