[Abstract]:With the rapid development and popularization of Internet, people pay more and more attention to the research of three-dimensional technology Web3D. How to design and implement a digital exhibition system on the network has become a research hotspot. This paper mainly studies the design and implementation of digital aviation library system based on virtual reality technology, computer network technology, human-computer interaction technology, database technology and network. The main contents of this thesis include four parts: 1) VRML/X3D optimization modeling of 3D models (mainly exhibition hall model and aircraft model) and X3D texture technology are studied and applied. Several methods to improve the operating efficiency of the system and the realism of X3D scene are given. 2) the database of digital aviation library system is designed and implemented, which is used to store data information such as X3D model, texture and so on. 3) the interaction mechanism of virtual reality design language X3D and external programming language is studied, and the method of communication among X3D, JavaScript and Java is put forward, which solves the problem of interaction between Java Applet and X3D scene in web pages, and at the same time combines the database of the system. The parameter design function of the network digital aviation library is realized, and the dynamic design of the aircraft model, texture, illumination and navigation scene effect of the digital aviation library can be realized on Web. All kinds of digital aviation pavilions can be designed efficiently by setting the parameters. 4) the combination mechanism of Ajax technology, X3D technology and XML technology is studied, which solves the problem of communication between X3D scene and database, and realizes the virtual display function of network digital aviation library. Aeronautical pavilions can be accessed through design or retrieval patterns on Web. The research results of this paper provide an effective solution for the design and implementation of the network digital library system.
