Working Model 3D:
Working Model 3D by Knowledge Revolution is a three-dimensional dynamics simulation program for personal computers. The dynamics engine is based on real world Newtonian mechanics. A snapshot of Working Model 3D is shown below.
 

To run the Export VRML program,  clicking on the Tools menu and select Export VRML. A snapshot of Export VRML and the About box are shown below.
 
 

Export VRML Translator:
The Export VRML program converts Working Model 3D data to VRML2.0 for playback purposes. The program uses Microsoft object linking and embedding (OLE ) control to get geometry, position, and orientation data and creates a VRML 2.0 output.  The VRML 2.0 output consist of the geometry and followed by a list of time in a row, called the " Key" and then followed by the list of positions and angles, called "keyValues" at different times. Click on the Readme file and the VB source code for more information.
