Research And Realization Of 3D Interactive Mode Virtual Campus System

The paper introduced Virtual Reality synoptically at first. It expatiated on thebasic factors and characters of the VR system. It expounded the hardware andsoftware realizations of VR also. The paper introduced synoptically the history ofVRML and its working theory and showed the expectation of VRML. It analyzed theexertion that technology of Virtual Reality acted on GIS (geography informationsystem). The paper putted forward the background,significance and researchfulcontents of this task on the basic. In the aspect of research and realization of VR system, the methods are departedinto several steps. At first, the prototype system should be in the progress ofrequirement analysis and function design. Then we combined VRML and JAVA toresolve this task. In the second steps we should analyze and compare these differentmodeling technologies and realize the building of 3d model. We should realize theconformity and function optimize of system model also. The emphasis of paper is toresearch and realize the alternation function of virtual campus system. It includes therealization of function such as cruise,controlling viewpoints,view in room,thealternation between 2d map and 3d model,collision,communications between JAVAand scene etc. At last the paper expatiated on the structure and theory of JDBC. Andrealize the design and application of the system database through JDBC. On the end of paper it gives a conclusion and expectation and widens the ideasabout VR system. The building of 3d alternation virtual campus system demonstratesthe feasibility and practicability that we can build VR system through JAVA andVRML.
