[Abstract]:Through the research and analysis of the whole engineering of earth-rock dam and the structure of the prototype component of earth-rock dam, according to the method of CAITA skeleton design, the three-dimensional prototype model of earth-rock dam is established. The 3D prototype model is developed with C # programming language, combined with the three-dimensional model browser and other plug-ins. The interactive operation and demonstration of 3D model and virtual teaching are realized, and finally a demonstration system of earth and rock dam design teaching is formed. The main contents of this paper are as follows: (1) the 3D prototype parameterization of earth-rock dam is divided into basic components of earth-rock dam, based on the basic theory of parameterization, and according to the basic rules of parameterized design. Various parameters of earth-rock dam components are extracted, including geometric parameters, assembly parameters, mechanical parameters and material parameters. Finally, parameterization of all components of earth-rock dam prototype, including dam top, dam body, slope protection, seepage prevention body and drainage facilities, is realized. It provides parameter support for the establishment of 3D parameterized model of earth-rock dam. (2) Three-dimensional modeling method and model interaction research. Through the research and analysis of the whole engineering of earth-rock dam and the prototype structure of earth-rock dam, Combined with CAITA skeleton design method, the integral skeleton model and cross-section skeleton model of earth-rock dam are established, and then the template library of earth-rock dam component is established by CATIA. The component template is assembled and designed according to the skeleton elements provided by the cross-section component skeleton model (that is, the coordinate of the component control point), and the three-dimensional model of a certain section of earth-rock dam is formed. Then assembly according to the whole skeleton model and finally form the three-dimensional model of the whole project. Then the 3DXML Player browser is redeveloped to realize the interactive demonstration of the model. (3) the research on the key technology of 3D teaching of earth-rockfill dam researches and analyzes the key technologies such as database 3DXMLDsoFramer-DwgViewX, etc. The research foundation for the realization of the system (4) the design and development of the earth and rock dam teaching and demonstration system according to the design specification of the earth and rock dam and the requirements of the teaching curriculum design, using C # to develop the relevant technology, Based on the 3D parameterized prototype of earth-rock dam, two-dimensional CAD graphics and course PPT, a virtual teaching and demonstration system for earth-rock dam is developed and designed in combination with a variety of third-party plug-ins to realize virtual teaching of earth-rock dam. Auxiliary course design and three-dimensional earth-rock dam project scene demonstration and so on. Finally, the research content is summarized, and the development of the earth-rock dam teaching and demonstration system is also prospected.
