Application Of Virtual Reality Technology On Internet

As a technology developed on the basis of computer graphics, robotics, mechanics, cybernetics and other sciences, virtual reality technology aims to build an artificial environment where people can perform various real-time activities such as driving, operating and designing in a "natural "way. virtual reality technology can provide "participants " with a feeling of being personally on the scene.As a main actor in the virtual environment,Userscan control any objects in the virtual environment arbitrarily and can get reaction in time.In the hyperspace of the information,he can get acknowledge with their own percipience and cognition ,and ,seek the solutin ,and form the new conception.the association of the virtual reality technology and Java technology intensify the interaction between the users and viryual reality technology .With the interface provided by Java,The user can control any objecs and change the attributes (such as position,angle,color and etc.).this paper formulizes application of the virtual reality technology in the system of the building seilling which uses the real three dimensions models to replace of static picture's and word's description.in the process of the practice,the paper analyses the difference between Javascript,Java claa and Java applet,and formulize the their applications in this system. Theoretically, virtual reality technology in this paper is not only restricted in the building selling ,could be widely used in military training & manoeuvre, medicine, education, engineering design and other fields.the system in this paper can realize the general management of the estate information and meet the customers' needsin purchase procedure .Therefore ,this system is worthful to be studied and extended.
