Construction Model Design And Demonstration Based On VRML

Three dimensional modeling and virtual realistic technique are becoming more and more mature with the development of Computer graphics, of which virtual realistic technique based on Internet becomes one of new topics in Computer graphics.Virtual Reality (VR), also called Near Boundary Technology, is the technique that has been improved quickly in the latest years. It can establish a man-machine environment which can not only resemble objective but also surpass objective. The important goal is the real experience and the interactive of the convenience natural man-machine. Virtual Reality has the extremely important significance of research and practical application with the wide application in Product promotion, architecture design, and construction examination. What this topic studies is one based on the VRML construction model demonstration system and it can be achieved by making good use of the language of VRMLå'ŒJava.This study aims at carrying out the construction model under the Web environment. Based on the aims, the following projects have been made:(1)The visitor may choose the construction at will the scene and the visit route. The visitors are allowed to choose any fields and routes at will and travel extensively so as to change the points by clicking mouse keyboard.(2)The visitor may make likely in the real world same dynamic behavior, for instance pushes the gate, turns on the light and so on.(3)The system should have a true mechanics property. Collide the examination function; for example, eradicate completely this type of circumstance that disobeys reality of"wear a wall but lead".(4) Modeling should be lifelike.(5)The system should combine a multimedia, such as the audio frequency and video frequency etc.(6) The good interactive ability of customers is necessary.
