Virtual Scene-aided Design And Display Technology And Its Application In The Real Estate,

While VR (Virtual Reality) technology is rapidly developing, its application areas extend to education, commerce, entertainment, ocean, finance, agriculture, real estate, etc. The applications of web based VR emerge with the development of the Internet. But these new applications confront two major problems. One is the difficulty in the process of modeling and designing of virtual scenes. The other is the restriction posed by transferring the large-scale scenes over the network. These two problems seriously limit the application and popularization of VR technology.There are three basic elements in scene design, which are sculpture, layout and colorway. The colorway scheme of the scene directly influences the overall effects of the whole scene, but it requires high art accomplishment. Therefore, this paper proposes a set of computer-aided designing schemes for the colorway of the virtual scenes. Color harmony algorithm under restrictions, color harmony algorithm of multiply views and color harmony algorithm based on CASE are brought forward by analyzing the principle of virtual scene designing, material restriction, and color expression in 3D environment.Aiming at network transferring problem of large-scale virtual scene, this paper put forward a solution combining the model dividing technique and stream transferring technique based on the web 3D standard X3D and MPEG-4 supporting stream transferring. But the time sequences of streaming transfer could only allow the virtual environment to be transferred in a fixed sequence. Using the model dividing technique, the virtual scene is divided into small-scale sub-scenes. Meanwhile, by combining the different transferring sequence of sub-scenes, this could not only reduce the network delay, but allow the combination of sub scenes in any sequences so that users can choose their own path to follow.Finally, we adapt these two technologies into real estate, and develop a virtual real estate system faces to new real estate management.
