The Virtual Reality Research And Applications Of 3d Modeling Techniques

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.In this paper, virtual reality modeling technology analyzes the development of the system studied the characteristics of virtual reality modeling technology, the main technical indicators and elements of virtual reality. Focuses on the key technology of virtual reality modeling, three-dimensional scene and model building process used in the optimization phase collision detection algorithm. In this paper, the traditional build process, the improved optimization process, the traditional optimization algorithm for collision detection algorithm is proposed improved algorithm, and applied to the satellite launch system modeling simulation scenarios to achieve the desired results.Paper describes in detail the various entities in the model of the system building process, and the scene of the integration and scheduling management system of the research on the problems encountered in the modeling process are summarized, put forward solutions. This key technology through the application of modeling and optimization, modeling the successful completion of related technologies for satellite launching the construction of the scene simulation system, the better to achieve a realistic, real-time and interactive purposes, for the future for large-scale virtual Construction of realistic scenes with large reference value.
