Vrml-based Virtual Reality Technology In The Remote Virtual Experimental Teaching In Applied Research

At present, the development of distance education in full swing, but in the course of development is experiencing a very difficult problems in the experimental teaching how to achieve remote online teaching can be part of the software or video presentations, but students how to operate hands? This issue has become the constraints of modern distance education network bottlenecks. However, the experimental teaching occupies a very important position, especially in the practical requirements of a strong science and engineering disciplines, it is an essential teaching and learning activities in the process. At the same time it is also practical training students manipulative ability, innovation and problem-solving ability of the vital link. With the computer network technology, multimedia technology and virtual reality technology and the continuing development of scientific research and practical problems to the need for further in-depth, virtual experimental technique has already begun getting mature and improve.This paper pointed out that the first meaning of the background to the study, described at home and abroad virtual experiment and the development of the virtual laboratory, and in distance education in the development and application. Then on virtual reality technology and the basic characteristics of the key issues on the virtual reality technology, as well as the major application areas in the field of education, the introduction of the VRML focused on the technical development, working principle and its application, and this led to a virtual Construction Laboratory advantage. Then study the remote virtual laboratory Construction of the theoretical foundation of the concept of long-distance virtual laboratory, characteristics, meaning and basic functions, as well as the construction of long-distance virtual laboratory key technologies and methods. VRML technology by using Java technology and the combination of virtual laboratory network construction. On this basis, using Java and VRML achieve the organic integration of the computer assembly to achieve the development of virtual experiment. Basically meeting the remote / local experimental teaching requirements.In this study, a detailed exploration of the following: VRML technology, combined with a powerful 3 DS MAX function of the various components of a computer 3-D modeling design, the virtual laboratory modeling technology VRML scenes of a modeling study of the VRML interactive, Java and VRML technology in the interface, you can use Java code to achieve a number of complex functions in order to achieve a certain degree of interaction; carefully studied the whole process of assembling computer virtual method, and its automatic the installation process for the simulation of the dynamic.Finally, this study was the development of a summary and outlook, the Institute completed only in the theoretical analysis of the virtual laboratory on the basis of a simple example, the realization of some functions. Some, particularly in the laboratory experimental data and experiments to be more cooperative in-depth study.
