[X3D-Public] US Patent 6,754,400

[Don Brutzman]

The Background node was approved by ISO as part of the VRML 97
international standard back in 1997.  This would appear to provide
prior art regarding several surprising claims made in 2001 by
patent 6754400.  Joe's helpful comments also make sense.

Jaime if you and/or others wish to relay this information you are welcome to.
Further if you and/or others wish to further encourage cooperation between
IVRPA and the non-profit Web3D Consortium, that will likely be great too.
Web3D Consortium was formed to protect the VRML/X3D specifications and it
is completely responsive to members.

This kind of productive collaboration is always driven by energetic
individuals who want to advance 3D graphics and "do the right thing."
Thanks to you and Tom for the information, I hope that this feedback
is helpful.

They have an interest in seeing the growth of interactive environments and they're very professional in their approach to expanding the art.
