Research on VRML Modeling for Web-Based Virtual Product Development

In this paper, we present the methods to develop the Web-based virtual product that is capable to dynamically simulate machine processes in solid graphics form through the Internet. The methods include the function-based virtual reality modeling language (VRML)shape modeling, which allows the content creators to describe any complex models with the mapping-based Route and Events description; the interaction of the virtual product realizing with drag sensors (DSs) of VRML, which allows users to be capable of handling virtual product with any desired precision. We illustrate the implementation of the proposed methods on the example of the interactive function-based shape modeling and DSs.
