【摘要】：當(dāng)代橋梁技術(shù)的發(fā)展依靠于計(jì)算機(jī)技術(shù)的發(fā)展，使得大規(guī)模計(jì)算可以在短時(shí)間內(nèi)完成，在橋梁計(jì)算理論和方法研究中已經(jīng)產(chǎn)生了不少的開源軟件供研究者共享，相比商業(yè)軟件，，這些開源軟件的計(jì)算方法是可讀的，是有利于研究發(fā)展的。然而有些軟件有很好的計(jì)算效果但卻沒有可視化的顯示界面，使數(shù)據(jù)的輸入與輸出比較困難。為此探索VTK這種高效便捷的開發(fā)工具在橋梁結(jié)構(gòu)顯示方面的應(yīng)用，為日后計(jì)算軟件的可視化做些初步工作。 有限元計(jì)算軟件已經(jīng)可以通過時(shí)間的積累處理海量的數(shù)據(jù)，但人的分析需要從模型顯示的直觀結(jié)果開始。隨著計(jì)算機(jī)技術(shù)的發(fā)展，人們對數(shù)據(jù)可視化顯示質(zhì)量有了更高要求，同時(shí)計(jì)算機(jī)技術(shù)也為這樣的需求提供了支持。VTK就是這樣一個(gè)工具，它的發(fā)展是伴隨著前一代可視化技術(shù)的衰落，它擁有更高的集成度因而可以適應(yīng)快速開發(fā)，它具備優(yōu)秀的流處理能力和有效的緩存功能因而可以適應(yīng)大量數(shù)據(jù)的實(shí)時(shí)渲染。VTK在國外已經(jīng)得到大力的發(fā)展，同時(shí)也得到一些機(jī)構(gòu)的支持，在我國一些如醫(yī)學(xué)、地理信息、機(jī)械等領(lǐng)域已經(jīng)對VTK開展了研究和應(yīng)用，在一些層面上證明其優(yōu)勢。但VTK的功能不止于此，國內(nèi)的發(fā)展仍然有局限性，教材的缺失、應(yīng)用領(lǐng)域狹窄、商業(yè)化程度不足成為了其當(dāng)前發(fā)展的障礙，但這些都掩蓋不了VTK的功能強(qiáng)大。 將VTK顯示窗口融合到MFC框架中，依靠MFC平臺為VTK模型參數(shù)提供GUI輸入輸出；選取適用于橋梁結(jié)構(gòu)顯示的VTK數(shù)據(jù)結(jié)構(gòu)構(gòu)建橋梁顯示元素；實(shí)現(xiàn)以界面交互方式進(jìn)行模型輸入；實(shí)現(xiàn)了多種橋梁單元截面的空間顯示；實(shí)現(xiàn)了基于一定數(shù)據(jù)規(guī)則的模型文件輸入輸出�；赩TK的類庫結(jié)構(gòu)實(shí)現(xiàn)適用于橋梁模型建立流程的程序結(jié)構(gòu)，為以后VTK在橋梁建模與模型處理方面進(jìn)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.
