The Research Of 3D Engine For Virtual Tourist Experience

With the rapid development of tourism trade's information technology and virtual reality technology, people start a new field of research—virtual tourist experience. In this field, in order to solve the traditional tourism mode's limits on time, location and weather, a virtual tourist experience environment was established based on virtual reality technology. It provides a new sustainable tourism mode, and it protects valuable tourism resources and ecological environm as well.Nowadays, the researches on virtual tourist experience focuses on the Panorama technology, while 3D engines on the gaming, military, education and medical fields. Aiming at the present situation, this paper pay attention to the research of 3D virtual tourist experience, and the main works are as follows:1. Propose the concept of Virtual tourist experience, analysis and compare different kinds of vitual technology and rendering technology.2. Study modeling technology, 3D engine technology,interactive technology, analysis their effects in virtual tourist experience field, and design data model and engine structure.3. Propose a 3D virtual tourist experience engine design pattern, implement the navigation system, regional navigation and free viewpoint function of the engine.
