【摘要】： 本文叙述了“综合交通客运枢纽功能与结构数值实验系统”中三维模块的设计与实现过程。整个实验系统主要由四个模块构成:建模模块、仿真模块、分析实验模块和三维仿真模块。主要流程是:用户首先使用建模模块进行建模,要导入由AutoCAD绘制好的枢纽平面图,按照系统需要进行修改,修改后作为场景,通过建模系统的各项功能最后输出一个无误的模型文件。仿真模块导入无误模型文件后进行仿真,同时可以输出仿真结果文件。分析实验模块导入仿真结果文件进行分析,并可产生一个分析结果文件。本文所介绍的三维仿真模块是个更加独立的模块,具有建模与仿真的功能,但不具备分析的功能,它通过导入各种三维模型或纹理图片作为场景,导入仿真结果文件作为数据,最终进行逼真的三维仿真结果的重现。本三维模块是基于Direct3D技术开发。该技术是Microsoft公司开发的交互多媒体应用程序接口DirectX的组成部分,它为程序员提供了一个实现三维图形的与硬件无关的应用程序接口。三维模块在实现细节上,使用骨骼动画技术,使人体或车辆在仿真运动中更加生动;使用蒙皮技术,使场景更加逼真;使用顶点索引混合,提高了图形平滑度和系统运行的效率;使用广告板技术,实现了图片的三维化显示;使用MSXML控件,用于方便地读写XML数据。本学位论文来自中国科学技术部的国家高技术研究发展计划(863计划)专题课题“综合交通客运枢纽功能与结构数值实验系统”。项目编号:2007AA11Z124。课题类型:探索导向类。技术领域:现代交通技术。专题名称:重大交通基础设施核心技术。作者负责三维模块的设计和开发。该模块的所有代码和研究成果,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.
