Dynamic three-dimensional virtual scene design based on VRML

The study of this paper is based on VRML (Virtual Reality Modeling Language) and virtual scene dynamic model realization. In order to overcome the insufficiency of using VRML on generating dynamic scenes, this paper mainly embeds JavaScript virtual scene into the virtual external language and viewer interaction; it also use JavaScript VRML node in perfect position and orientation interpolator node, which cannot be obtain information about visitors from the interpolator browser due to the lack of the JavaScript language processing results. Consequently, with the interpolator node as input events, the paper achieves better interaction between different nodes and the scenes with the viewer´s interactive features.
