[x3d-public] whither geovrml.org ?

[Brutzman, Donald (Don) (CIV)]

Mike, Martin (hello again Mr. Incredible sir), wondering what do you think
about this?

 

Current testing of VRML validation for X3D Example Archives reveals that
geovrml.org is no longer supported, and had not been noticed previously.
Interesting.

The geovrml.org site was originally used to host VRML and X3D geospatial
nodes, and was instrumental for their successful development and
documentation as the X3D Geospatial Component in the ISO/IEC standard.

My GeoSpatial X3D slideset includes a little history, no doubt Mike has even
more.

 

*	History: GeoVRML 
*	Geospatial referencing has always been a goal of X3D in order to
make models most useful.
*	The core design efforts for geospatial X3D were performed by GeoVRML
working group.
*	This design has been carefully evolved over time to match practical
experience gained by producing ever-larger geospatial model.

Given our successful standardization and continuing deployment, not sure we
actually need geovrml.org any more - but on the other hand, maybe there were
some historic assets that deserve to be archived.  We might use web3d.org
for that.

 

Of further note, Nicholas was recently engaged in SIGGRAPH 50-Year History
efforts.  He has a good understanding of these imperatives and
opportunities.

 

Thanks all for considering this.

 



 

all the best, Don
