中文摘要：

A collaborative virtual modeling environment based on VRML is presented as a sugarcane harvester modeling framework, and is illustrated with the implemented software that can using I_DEAS, Smarteam, and Conceptual Innovation Design System (CIDS) as the supporting platform, which is powerful enough to meet the demands of different real life applications. It is possible to perform collaborative interactive modifications with concurrent synchronous visualization at each client computer with any required level of detail. The platform provides a product modeling and assembling environment, and the product data among I_DEAS, Smarteam and CIDS can be exchanged.
