Abstract


A three-dimensional network teaching is on the Internet show the way of a three-dimensional teaching environments and processes, including the three-dimensional virtual classroom to establish virtual teachers to explain the scene, virtual students on-site lectures and questioning aspects. With the rapid development of Internet bandwidth, virtual reality environment on the Internet has become one of the directions of the development of computer technology. \Internet-based virtual reality technology to solve the virtual scene roaming, virtual characters in the same scene synchronization, PPT files and video files play in the three-dimensional scene on real teaching a variety of interactive tools The virtual interaction be achieved on the network. For the implementation of universal education and continuing education provides a more vivid, lively means of achieving better social. This article focuses on the research work of the following aspects: First, the status quo of today's more popular virtual classroom, and that the lack of vivid classic web-based virtual classroom, virtual classroom requires a higher hardware-based video conferencing system cost, and students subject to the constraints of the hardware environment. Internet-based 3D virtual classroom, students participate in only one Internet terminal, you can enter the virtual classroom for interactive learning, strong sense of participation. Then the 3D virtual teaching platform core technology, elaborated on the virtual campus environment, the character models and scenes model to build the technology used to analyze the function and structure of the application server and the synchronization server. Determined the basic components of the virtual classroom, classroom plot courseware player, video remote control, writing on the blackboard simulation, character interaction, and the planning and design of various components of the scene; for courseware synchronization, video synchronization, dialogue control, character behavior synchronization synchronization logic design, especially in the video synchronization link, the use of real-time transmission control parameters to ease the the playback synchronization network pressure. Next, virtual teaching and learning activities, PPT playback technology, video playback technology implementations are discussed, combined with the current popular AJAX, JSP, Servlet technology, integration of the design logic, and describes the scene of the virtual classroom and user interface.
