【摘要】： 本文敘述了“綜合交通客運(yùn)樞紐功能與結(jié)構(gòu)數(shù)值實驗系統(tǒng)”中三維模塊的設(shè)計與實現(xiàn)過程。整個實驗系統(tǒng)主要由四個模塊構(gòu)成:建模模塊、仿真模塊、分析實驗?zāi)K和三維仿真模塊。主要流程是:用戶首先使用建模模塊進(jìn)行建模,要導(dǎo)入由AutoCAD繪制好的樞紐平面圖,按照系統(tǒng)需要進(jìn)行修改,修改后作為場景,通過建模系統(tǒng)的各項功能最后輸出一個無誤的模型文件。仿真模塊導(dǎo)入無誤模型文件后進(jìn)行仿真,同時可以輸出仿真結(jié)果文件。分析實驗?zāi)K導(dǎo)入仿真結(jié)果文件進(jìn)行分析,并可產(chǎn)生一個分析結(jié)果文件。本文所介紹的三維仿真模塊是個更加獨(dú)立的模塊,具有建模與仿真的功能,但不具備分析的功能,它通過導(dǎo)入各種三維模型或紋理圖片作為場景,導(dǎo)入仿真結(jié)果文件作為數(shù)據(jù),最終進(jìn)行逼真的三維仿真結(jié)果的重現(xiàn)。 本三維模塊是基于Direct3D技術(shù)開發(fā)。該技術(shù)是Microsoft公司開發(fā)的交互多媒體應(yīng)用程序接口DirectX的組成部分,它為程序員提供了一個實現(xiàn)三維圖形的與硬件無關(guān)的應(yīng)用程序接口。三維模塊在實現(xiàn)細(xì)節(jié)上,使用骨骼動畫技術(shù),使人體或車輛在仿真運(yùn)動中更加生動;使用蒙皮技術(shù),使場景更加逼真;使用頂點(diǎn)索引混合,提高了圖形平滑度和系統(tǒng)運(yùn)行的效率;使用廣告板技術(shù),實現(xiàn)了圖片的三維化顯示;使用MSXML控件,用于方便地讀寫XML數(shù)據(jù)。 本學(xué)位論文來自中國科學(xué)技術(shù)部的國家高技術(shù)研究發(fā)展計劃(863計劃)專題課題“綜合交通客運(yùn)樞紐功能與結(jié)構(gòu)數(shù)值實驗系統(tǒng)”。項目編號:2007AA11Z124。課題類型:探索導(dǎo)向類。技術(shù)領(lǐng)域:現(xiàn)代交通技術(shù)。專題名稱:重大交通基礎(chǔ)設(shè)施核心技術(shù)。作者負(fù)責(zé)三維模塊的設(shè)計和開發(fā)。該模塊的所有代碼和研究成果,均由作者完成。
[Abstract]:This paper describes the design and implementation of three dimensional modules in the Integrated passenger Transport Hub function and structure numerical Experimental system. The whole experimental system is composed of four modules: modeling module, simulation module, and so on. The main flow is that the user first uses the modeling module to model, to import the hub plan drawn by AutoCAD, to modify it according to the need of the system, and to modify it as a scene. Finally, an unmistakable model file is output through the various functions of the modeling system. The simulation module imports the correct model file to carry on the simulation, at the same time can output the simulation result file. The analysis experiment module imports the simulation result file to carry on the analysis, The 3D simulation module introduced in this paper is a more independent module, which has the function of modeling and simulation, but it does not have the function of analysis. The simulation result file is imported as the data, and the realistic 3D simulation result is reproduced. This 3D module is based on Direct3D technology, which is the component of DirectX, an interactive multimedia application program interface developed by Microsoft Company. It provides a hardware-independent interface for programmers to implement 3D graphics. 3D modules use skeletal animation technology to make people or vehicles more vivid in simulated motion, using skinning technology. It makes the scene more realistic; using vertex index mixing to improve the smoothness of graphics and the efficiency of system running; using the technology of advertising board to realize the three-dimensional display of pictures; using MSXML control to read and write XML data conveniently. This dissertation is from the National High Technology Research and Development Program of the Ministry of Science and Technology of China, China's "Integrated passenger Transport Hub function and structure numerical Experimental system". Project No.: 2007AA11Z124. subject type: exploration orientation. Class. Technical field: modern transportation technology. Thematic title: core technologies for major transport infrastructure. The author is responsible for the design and development of 3D modules. All codes and research results of the module, All by the author.
