Web-based Virtual Store

Along with the development of the computer and network, the commerce in our country is stepping in the era of network. The information-network brought by Infobahn transfuse brood into the commerce, it has expanded the trade space for merchant,What we can do for the commerce with the technology of computer and network is an exigent question for discussion.At present, the virtual shop base on Internet show the information of commodity just by the text and image currently, it can not exhibit the shape and the function of the product to the consumer satisfactorily, so it is hard to be trust by the consumer. The study of this item tries to break the situation by imports the three-dimension virtual reality interactive environment; bring a qualitative change to the virtual shop on Internet.This article study the technology to realize the virtual shop based on web by VRML basically, the contents and the method adopted is show below:1. Research on the technology to exhibit virtual reality product based on web. It studies the key technique to show the virtual reality commodity using VRML mainly, the details are:(1) The modeling technique on virtual reality product. It constructs the model with the three-dimension design software such as 3DSMAX and AutoCAD first, then, converts the output to the style of VRML, edit it by the VrmlPad at last.(2) The interactive technique on virtual reality product. It constructs the interaction on model using the VRML node like Touch Sensor Cylinder Sensor Plane Sensor Sphere Sensor Proximity Sensor and Visibility Sensor.2. The research of wandering technology in virtual reality scene based on web. It studies the key technique to construct the virtual shop scene and wander in it mainly. The details are:(1) The modeling technique on virtual reality scene. It constructs the three-dimension scene with 3DSMAX then converts the output to the style of VRML.(2) The wandering technique in virtual scene. Construct the wandering and interaction in virtual scene by the technique of LOD...
