【摘要】：当代桥梁技术的发展依靠于计算机技术的发展，使得大规模计算可以在短时间内完成，在桥梁计算理论和方法研究中已经产生了不少的开源软件供研究者共享，相比商业软件，，这些开源软件的计算方法是可读的，是有利于研究发展的。然而有些软件有很好的计算效果但却没有可视化的显示界面，使数据的输入与输出比较困难。为此探索VTK这种高效便捷的开发工具在桥梁结构显示方面的应用，为日后计算软件的可视化做些初步工作。有限元计算软件已经可以通过时间的积累处理海量的数据，但人的分析需要从模型显示的直观结果开始。随着计算机技术的发展，人们对数据可视化显示质量有了更高要求，同时计算机技术也为这样的需求提供了支持。VTK就是这样一个工具，它的发展是伴随着前一代可视化技术的衰落，它拥有更高的集成度因而可以适应快速开发，它具备优秀的流处理能力和有效的缓存功能因而可以适应大量数据的实时渲染。VTK在国外已经得到大力的发展，同时也得到一些机构的支持，在我国一些如医学、地理信息、机械等领域已经对VTK开展了研究和应用，在一些层面上证明其优势。但VTK的功能不止于此，国内的发展仍然有局限性，教材的缺失、应用领域狭窄、商业化程度不足成为了其当前发展的障碍，但这些都掩盖不了VTK的功能强大。将VTK显示窗口融合到MFC框架中，依靠MFC平台为VTK模型参数提供GUI输入输出；选取适用于桥梁结构显示的VTK数据结构构建桥梁显示元素；实现以界面交互方式进行模型输入；实现了多种桥梁单元截面的空间显示；实现了基于一定数据规则的模型文件输入输出。基于VTK的类库结构实现适用于桥梁模型建立流程的程序结构，为以后VTK在桥梁建模与模型处理方面进行初步探索。
[Abstract]:The development of modern bridge technology relies on the computer technology, the large-scale computation can be completed in a short period of time, the bridge calculation theory and method has generated a lot of open source software for researchers to share, compared to commercial software, the open source software calculation method is readable, is conducive to research and development. However, some software has good calculation results but did not show the visual interface, so that the input and output data is difficult. To explore VTK this convenient and efficient development tools in bridge structure display applications, visual computing software for the day after doing some preliminary work.
The finite element calculation software has been through the accumulation of time dealing with massive data, but the analysis from model visual display results. With the development of computer technology, people have a higher quality requirements for data visualization, and computer technology for this requirement provides support for.VTK is a tool it is the development of visualization technology has been accompanied by a decline in the previous generation, it has a higher degree of integration and can adapt to the rapid development, it has the excellent ability of stream processing and effective cache which can adapt to real-time rendering of a large number of.VTK data has been vigorously developed in foreign countries, but also get some institutional support in some, such as medicine, China's geographic information, machinery and other fields have carried out research and application of VTK, prove its advantages in some aspects. But the power of VTK to more than In this regard, the domestic development still has limitations. Lack of teaching materials, narrow application fields and insufficient commercialization become obstacles to its current development, but these can not cover the powerful function of VTK.
The VTK display window into MFC framework, relying on the MFC platform for the VTK model parameters of GUI input and output; select suitable data structure of VTK bridge structure shows the construction of bridge display elements; realize the model input to achieve a variety of interactive interface; bridge unit section space display; realize the model file input and output data based on the rules. The library structure VTK implementation procedure structure in bridge model is established based on process, for VTK preliminary exploration in bridge modeling and model processing.
