Design And Realization Of Multimedia Learning Visual System Based On VRML

Virtual Reality technology is one of the hot research areas. Among its wide range of applications, virtual reality technology in the field of teaching has played a positive role in support. Under the guidance of the constructivist theory of teaching, multimedia technology and network technology to link a variety of techniques, combining the teaching discipline and helping learners constructing learning environment in the virtual scenes to carry out the meaning construction and the new way to study at the new age of E-Learning.Constructivist learning theory, which emphasizes the centrality of students, emphasizes the important effect of abundance "situation" for the meaning construction, and emphasizes the important effect of various learning scenes. Virtual Reality technology provides technical supports for the working and learning simulation environment, and deeply fit the theory of constructivist learning. Learners interact with the learning situation through the simulation of the teaching environment, and achieve independent learning under E-learning mode.First, this article starting with the theory of constructivist and the viewport of E-learning, shows the importance of virtual reality technology in the field of teaching. It describes what virtual reality technology is, and introduces the current use and development of virtual reality. It also introduces the VRML (Virtual Reality Modeling Language), and describes the common techniques in the building of virtual reality scenes, then expounds the meaning and effect of what this design does to the author's practical work.Second, starting with the completed teaching media simulation system, expounds the key technology and system design to complete the system. It introduces how to build the models for virtual system by using 3DS MAX, and the methods to build the optimization models. It shows the adding process of using VRMLPad to interact with establishing the models of teaching environment, when creating a virtual teaching environment. And it explains the ideas and methods of using Cult3D to interact with the models of teaching equipments established by 3DS MAX.At Last, This article describes the methods of the system integration by using Authorware, and also shows how to view the models through the web page. This system is an effective additional teaching tool to apply on the course teaching, and it can help students achieving digital learning.
