Research Of 3D Modeling Based On Virtual Reality Technology

With the development of science and technology,the complexity of models that constructed and dealled with in the computer graphics,and the virtual reality is higher and higher.There are special requests for the computation speed,the transmission speed,and the real-time display of the computer in these fields,which makes the contradiction between the model complexity and the computer hardware performance more and more obvious.Thus the model simplification technology was developed at the historic moment.Recently the model simplification technology became the focus studied in the computer graphics.One part work of this paper is to carry on the significative exploration in this aspect.The suppositional building pleasure trip technology pretends to perform in architectural design , the interior building , real estate develops , game designs that waiting for aspect to have the very vast application prospect. Its immersing feels , interactive nature and synthetical real time nature effect are that the tradition flat surface effect pursues and the animated cartoon broadcasts what has no way to reach.This paper studies the virtual roaming 3D graphics technology and related theoretical foundation, and this has been developed based on the MFC and OpenGL buildings virtual roaming system. The computer system with the basic I / O device for three-dimensional virtual scene in the roaming function, and provides a friendly user interface and virtual MFC construction of the multi-scene observation angle, multi-roaming mode selection. Main work and research results include:1.On the modeling scene, 3 DS document read roaming, as well as the virtual scene I / O control technology, and to programming. In the virtual roaming on key technologies on the basis of the establishment of the function of the camera, Scene model input function category and type of data model, improve the functions of the procedures, and optimize the structure of the procedure.2. Developed a set of MFC and OpenGL based on the simple building virtual roaming system. Windows users through friendly interface, provides users with multi-angle observations, multi-mode roaming options to meet the user's various roaming requirements.
