[geovrml] Re: Rez terrain modelling/translator too update

[Martin Reddy <reddy@AI.SRI.COM>]

Hi Chris,

This is great - many thanks for continuing this effort. I have added a news
item to the GeoVRML.org web site for this. There is of course already a link
to the Rez tools from the "Tools" page on the site.

On your site, I notice that links for the GeoVRML world example are all
broken. If you able to easily fix these, including the ZIP file, then I will
download and add this example to the GeoVRML Example Content web page too.

As for Java3D work, see my next message for some interesting developments...

Cheers,

Martin.
