Photographic Simulation System Design And Development

At present,as one popular technology used in education,Virtual Reality was suffered the concern of many educators.How to integrate VR with education and improve VR's service ability in education has becomed one exploring aim of many educators.This thesis selected Virtual Reality Modeling Language as technical support,combined VRML with photoing experimentconcentrate on creating a virtual photoing emulational experiment system based network,explored Virtual Experiment,which was the outcome of integrating VR technology with distance education.Based on detailed photoing technology curriculum,this paper designed and explored six experiments.and researched on the main technical problems,for example:the realization of Interaction function of camera model(focusing, adjusting aperture and shutter), the realization of bringing photoes in real time,the realization of changing photoes' effection as adjusting focus,the realization of changing photoes' effection as adjusting aperture and shutter which controlled exposal amount,and the exploitation of virtual school.In actual development process,we found that the technique of EA1 no longer applied in the environment of JDK1.4 or advanced edition, so we brought forward a new mechanism of VR communicated with Java:VR-JS-Java.In the end,the whole system passed by tryout, and confirmed that the virtual experiment based network had excellent characteristics of interactivity and immersion,and other advantages,such as benefit increasing study interesting and efficiency of learners,easily used by distance learners,saved educational resources,and so on.
