Research Of Virtual Physics Experiment Based On Web 3D

Along with the network technology and the virtual reality technology's development, the development of the virtual experiment based on network and the correlation questions become the current distance learning research focus, and they have already obtained more and more attention from educator. Using virtual experiment in education can reduce the experimental outlay, break through the space-time restriction of traditional experiment,and evade the dangerous operation in traditional experiment. Most present virtual experiments differ greatly from the true experiments in such aspects as sense of reality and interaction and can not meet the demand of practical teaching, while the development of Web 3D resolve all of the problem. The technology of Web3D is a new network three dimensional technology. The network virtual experiments what are made by this technology have good sense of interaction and immersion, so it has already obtained more and more attention from investigator of distance experiment.This thesis focuses on applications of Web 3D technology in experiment teaching. Firstly, virtual reality technology which is close connected to Web 3D technology is introduced in this paper, including the basic concept and the types. Secondly, the key points of virtual experiment are discussed, including the basic concept, the types and theory basis using in experiment teaching. Then the author shows some kinds of WEB3D technology, points out the difference among them and summarizes the popular method of developing network virtual experiment, which is to establish three dimensional modeling and design interaction separately, to establish three dimensional modeling in professional modeling software and to design interaction in professional interaction software, such as Cult 3D Designer. At last the author takes the virtual experiment development of spectrometer's redresses for example to introduce the process of developing virtual experiment using Web 3D technology.
