Hello Sean, I have been trying to read up different license policy but I have not yet been able to figure out which could be supported by BRL-CAD. I have been looking at libx3d and freewrl which are both GNU Lesser Public License and also Coin3D which is BSD 3-clause license.I am really familiar with freewrl but I could not get much help from their mailing list as they instead gave me directives to check on other softwares while I wanted to use it for the vrml-g converter. Openvrml just has support for vrml-encoded-x3d and not x3d-xml. I would really be grateful to get pointers to some license compatible library with good support for x3d. I strongly believe that if I am giving the chance to develop a custom importer for BRL-CAD I would make it as robust as possible but I would first ensure that I conforms to the web3d standards and BRL-CAD coding standard then add support for primitives and polygons before moving to other representation like nurbs even after the GSoC period. Having worked with other libraries I have some understanding of how the parsing is done and can actually develop a solid parser, including the xml parsing.
