本文在VRML 虚拟现实应用平台上建立了可在Web 下运行的贴标机虚拟系统。提出了采用插补器和s cript 节点实现贴标机的行为仿真的方法。此外，还提出了一种利用Solidworks 和polytrans 相互结合而实现的在虚拟环境下的贴标机的快速建模方法。关键词：贴标机；虚拟现实；VRML；节点Abstract：A method for building a web based simulation system of the labeling machine is proposed. We realized virtual manipulation of labeling machine using Interpolator Node and s cript Node. Further more, this paper introduced a rapid modeling method in the virtual environment which is realized by Solidworks and PolyTrans, and its effect is satisfactory.Keywords: Labeling machine; Virtual reality; VRML; Node
