Three Dimensional Modeling And Simulation Training System For Beam,pillar And Board

In the field of architectural professional teaching,there are few three-dimensional building simulation teaching systems,and the research of mature architecture simulation is not based on education,most of them are used for commercial software with high professional degree.so many details and short problems have appeared in the process of developing 3D architecture simulation teaching system.In order to solve the problems of modeling,drawing,development mode and framework encountered in the process of developing the 3D architecture simulation teaching system,by describing the research on building component knowledge and the development of the evaluation module in the teaching system,this thesis has proposed and implemented some feasible solutions for the above problems encountered in the development process.The contributions of this thesis are as follows:(1)An object-oriented modeling scheme based on building members' beams,pillars,boards and internal reinforcement of components was proposed and implemented.Whether in the process of software development or in the later stage of maintenance and expansion,a good model and framework can all get twice the result with half the effort.Therefore,in order to improve the robustness of the architecture teaching simulation system and the extension of the later development,and avoid the increase in the difficulty caused by some logical problems,a systematic and scientific model of object oriented is needed.(2)For the simulation reality of building components and internal reinforcement,this thesis proposes a method to use OpenGL to create 3D scenes to display 3D and three views.Because of the technical difficulties and the waste of four times the memory resource with the use of OpenGL at the same time creating four scenes(a 3D scene and three views scene),we need a way to both save memory resources and reduce technical difficulty to draw scenes and architectural components.(3)To reduce system coupling,the development of the appraisal system adopts a modular development method,and the entire appraisal system is divided into two modules: the question and the answer.Between the two modules,which are independently designed and developed,the data is connected and interacted through the database because the data of two modules is stored in the same database.The part of the three-dimensional simulation display is added to the answer module to satisfy the student to dynamically control the transformation of the reinforcing bars in the threedimensional simulation map by modifying the question answer.
