Research To The 3D Modeling Applied In Virtual Reality

In recent years, Virtual Reality (VR) Technology has been paid extensive attention in computer field. Virtual Reality Technology is an important direction of the high-tech developments in the twenty-first century. 3D modeling technology is the most important part and one of the key technologies of virtual reality. 3D modeling technology is the foundation of the VR system and the key step and technology of all the applications.Based on the fundamental of the computer graphics, some theory of the computer graphics that related with the paper are introduced. It includes basic content of the computer graphics, graphics transformation technology and sense of reality graphics technology. Based on this, it introduces virtual reality-oriented modeling technology. Vitual Reality modeling technology trait, main technology target, basic content, implementation manner and key technology are introduced in virtual reality-oriented modeling technology. These lay solid theory foundation for upper application study of the system. Take Combination Station Scene for instance, on the basis of three-dimensional scene construction flow, from data collection and pretreatment, three-dimensional scene construction method, scene integration and schedule management aspects, three-dimensional virtual scene construction process and method are introduced. Based on this, 3D modeling optimization method is studied. It includes 3D modeling optimization flow, structure optimization, model optimization and hierarchy simplification algorithm based on k_dop. This is one of the innovation points, modeling optimization run through whole modeling process. In the last course of the analysis and study, from system analysis and design, system three-dimensional virtual scene constuction, database technology, scene representation art and three-dimensional object movement simulation aspects, application implementation based on 3D modeling technology in the combination station system is discribed. Based on implementation, familiar question in system modeling and solutions are discussed, system three-dimensional model rapid display technology is summarized and modeling optimization algorithm compare analysis is discussed.
