| In the domestic field of education, virtual reality technology more and moreattention, and has entered the practical stage.3D virtual learning environment into thevirtual reality technology can bring a better learning experience for learners to solvethe traditional teaching of funds to invest limited and experimental teachingequipment is relatively backward. It promotes the training and development of thestudents’ practical abilities and innovative thinking ability. Desktop3D virtuallearning environment is an easy to quickly develop, and it is suitable for China’seducational development of virtual learning environment, and provides a new learningplatform for lifelong learning to solve the problem of distance education is not easy topractice teaching.Broadly speaking, virtualization is the help of the symbolic intermediary beyondreality to construct non-realistic real-world capabilities, activities, processes andresults. Virtual technology has gone through five stages: virtual of objects, virtual oflanguage, virtual of symbolic image and virtual of digital. Now mainstream thinkingof the virtual technology of virtual reality technology is based on the number of3Dcomputer graphics technology. It will be limited in the virtual3D digital, and itscharacteristics are summarized as immersive, interactive and ideas.From the early1960s, it began in the field of education that theory and practiceof application of virtual reality technology. From the early1960s, theoretical researchand practical study of virtual reality technology applications in the field of education.To the beginning of the21st century, it began to appear3D virtual learningenvironment with the continuous development of the virtual learning environment andmaturity of3D virtual reality technology. In the current, desktop3D virtual learningenvironment phase can reach the best balance of the development of technicaldifficulty and experience effects, and it is also easy application. Desktop3D virtuallearning environment is based on desktop virtual reality technology to constructdigital three-dimensional learning environment. Its main advantage is to promote theindependence of learning, break through the constraints of time, avoid the risk of learning, and save the cost of teaching.According to David H.Jonassen`s two-dimensional graph theory, I designteaching mode of Desktop3D Virtual Learning Environment called "open andself-learning". It is suitable for individual learner or more learners. Based on Thetheory of metaphorical projection, the structural frame can be projected as the scenelayer, learning layer, navigation layer and interactive layer. According to the sequenceand characteristics of the development, the development process is divided into needsanalysis, program design and system development. It introduces that the developmentprocess of desktop3D virtual learning environment and its core3D virtual realitytechnology through the design and development of photography virtual experiment.Finally, the present work were summed up and summarized, and pointed out theinsufficient and further research work. Finally, it summarized and the summary of thisarticle, and pointed out the insufficient and further research work. |
