I am researching the options for rendering an existing osg graph in a
networked client server environment, and I am looking for suggestions.
The ideal would be some sort of ready made solution, but I do not rule
out some development.
Firstly, here are the basic techniques that come to mind, what have I
missed?
1. Export the graph to a format supported by some existing client
server solution. Does anyone know of one? A thin or fat client would
work, the only mandatory being that windows should be among the client
platforms supported.
2. Use an existing client server technology that directly supports
osg. Michael Gronagers OsgAX is the only one I am aware of, but
Michael is no longer Actively J developing it. Are there any others I
have missed? I have noticed a number of attempts on the Java front
over the last couple of years, but nothing definite.
3. Roll my own. Would an ActiveX implementation of Robert’s new
graphics window stuff make sense. I have not looked into it, so I have
no idea!
Any help gratefully received.

We are working on Firefox / IE plugin, based on osgProducer.
you can try a pre-alpha by opening in firefox (tested with 2.0 and
1.5.x) the link
http://3d.cineca.it/storage/terrain/campania/
It should direct you to an xpi installer.
depending on windows releaseses, the installation procedure can vary:
usually if you download the xpi and open it with the firefox executable
it should install itself
into the plugin folder of firefox.
At the end of the installation, if you reload the page you should see an
OSG window on an osgdem generated view of the Naples gulf
The example page shows a paged terrain and some switching ive files
(sorry, it is in italian, click on the rightmost menu to activate
optional files)
in order to use the standard trackball manipulator, select 3buttons in
the button action select
if you see slow paging, try clicking + button, it decrease the draw
framerate to give more time to paging thread.
An improved version is on the the way, (Carlo Camporesi is busy working
at it).
Our plan is to release everything as Open Source, either GPL or LGPL as
soon as we reach a minimum of functionality to show.
We are also thinking how to add flexibility to this code by decoupling
the OSG related application to the Mozilla or IE coupled code.
If you find it interesting, let us know.
Best regards
Luigi Calori
