Hi Stephen,
While I am interested in learning more about your code, I am not
personally looking to start an uber 3D geo project, rather just trying
to understand how far along we are, moving towards an open 3d geoweb,
particularly for handheld AR apps.
I'm also simply trying to understand why or why not start with a very
simple 3D coordinate descriptor, e.g. a 3D georss, or even KML. I do
have some hopes that some of the many 3D interoperability issues will
be worked out as KML is absorbed into the OGC. e.g both CityML, and
X3d/vrml groups have had some discussions with google at the OGC
regarding KML interoperability. Like wise, collada proponents are
similarly engaged with advocates of other 3D CAD schemes.
All of the standards work may take years, but in the meantime, I suspect
people will want to start using a very simple 3D geoannotation for
handheld location apps. I have heard that Nokia and others are
investing large funds in rolling out AR services, so it's not too early
to start consideration of a widely useful open spec for 3D geoannotations.
Mike

media, overlaid on the realworld view.
I've been working on this for a while, and would be interested in
releasing the tools themselves as open source. I would retain my
photographs as copyright, but that's a small issue that shouldn't be a
problem in any way.
Also noting the absence of simple semantic 3D links between
georss-kml- wfs/gml-arcgis, cad collada), and VR open models (eg.
ibm/SL, vrml), oh and cityml, to and innumerable others. Fundamental
requirment is an atomically simple coordinate description eg. a 3d
georss, and then a robust consensus foss app stack for people to
casually or formally annotate - near field - 3d geospace and,
ideally for importing & mashing cool 3D data from other domains,
3Dgis, CAD, games, virtual worlds
I would also be interested in merging this with the earlier discussed
Open Street View. I think we're talking about a project here, so can
we please start talking about this and then form a group?
or care to specultate on an open geo stack for AR and immersive media?
I think it would be a mistake to worry about setting standards for
interoperability before having a starting point that actually works.
Having said that, it's not all that hard to get something up onto the
screen which then becomes a form of documentation that drives further
effort.
Rather than endless discussions of technical specifications, how about
we try and drive this through a series of demonstrations? I am
involved with Away3d ( http://away3d.com ), which could be a good
basis for now, until OpenGL ES 2.0 comes with WhatWG.
Steve.
