Mathematica graphics to VRML converter

m2wrl.m (Mathematica to wrl VRML format) provides a set of functions to convert Mathematica 3D graphics objects to virtual reality modeling language (VRML) version 1.0 documents.

Limitations: Only Polygon graphic primitives are supported. However, the polygons are constructed by using a shared set of points, which makes the rendering faster and gives the VRML browser better hints how to shade the polygons.

Note: The program is free software; you can redistribute it and/or modify it. It is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
