Abstract
With the development of information technology, virtual reality has been widely used in military, commercial, educational and entertainment industries. By applying virtual reality technology to traditional library, this paper establishes a virtual digital library system. The system takes the library of NJUPT as the designing and modeling object, uses Unity3D as the virtual reality engine to develop the virtual library system, realizing scene construction, the virtual roaming, the scene interaction and the book loaning inquiry and other functions of the virtual library. This paper presents a method for selecting books based on the method of Ray, and designs a Web Service interface to realize communication between virtual reality environment and library management system. The users can obtain immersive experiences in the virtual library, and also can get the location and the situation of the books in the virtual library by VR glasses, PCs and Smart Mobile Phones.
