OGC just approved as a Discussion Paper (i.e. not a spec but something
they want feedback on) an interface for 3-D visualization that might be
worth a look. Right now the OGC web site (www.opengis.org) seems to be
down, I think there was a nasty crash of some sort. I'll try to remember
to watch for the paper and post a URL when it's available.

The interface is in the spirit of the WMS interface, i.e. it doesn't
dictate how to build the guts of the view service, but talks about how
you might encode a request to such a service in an interoperable way. If
someone were to build a free software engine that could do it, that
would be a big plus.
