The study on priority-based location display in OPAC system

In order to provide user more accurate location of the book, we add the function of displaying location by dynamic 3D graphics and highlighting the bookshelf which the target book on to the existing system of OPAC. But the amount of information which is needed in the progress of importing model files presented to the user through Java3D is very large, and for reducing the data size of transmission, we bring in borrow priority in this paper, and define that it´s only the user who has the priority can check the dynamic 3D graphics of the target book.
