Virtual Experiment A Number Of Key Technical Studies

While Leaming Through Doing has been an important issue for modem web based Learning and Training, VRML & JAVA are paving the way for the future of online interactive virtual environment. The fundamental characteristics of web based virtual reality include ulmmersive, interactive and Multi-Sensitive? which makes modem E-Leaming more effective and convenient Based on the main technologies for virtual reality enhanced web based experiments, this thesis concentrates on the modeling, interaction, and animated explanation system, as well as multi-user technology for online virtual experiments environment. The paper begins from the charactetistics, current status of online virtual experiments, and describes the aim and content of our research work. Topics including the object oriented design of online virtual environment, construction of complex 3D model, and dynamic modification of virtual environment are covered, also, this thesis is trying to give details on generation of 3D real-time animated explanation system for virtual experiments environment In the field of multi-user virtual environment, discussions are given about shared VRML object, linking management, VRML content publication, and input sharing. At the end of this paper, both summary of our research and prospect of web based virtual reality are givert...
