x3d-public@web3d.org<BR>Betreff: [X3D-Public] The Network Sensor is not
enough<BR><BR></P>Dear members of the X3D-public<BR><BR>When comparing Network
sensor and DIS, you will find, that DIS is quite specialized, but it's easy
for the developer of the scene to use DIS, where the Network Sensor is very
general, but the scene author has to define and implement a lot of specifics,
before he can use the Network Sensor.<BR><BR>This was my impression at
least.<BR><BR>Such topics like<BR> - reusability of models and modules
(given a module is a part of the landscape)<BR> in
different scenes from different authors<BR> - implementing central
services, that are (currently) not available on the collaboration
server<BR> - interactivity and animation<BR><BR>are not very well
defined, so each company, each framework, each author uses very different
approaches.<BR><BR>It's my impression, at least.<BR><BR>If you agree to this,
the following text might be interesting for you, otherwise you can stop
reading here.<BR><BR>Since IMHO the Network Sensor has a lot of advantages,
too, I think it would be worth to play around with the possibilities (goal is
an evolution of the standard) and started an open source project, which is
mainly a playground.<BR><BR>A short introduction at: <A
href="http://smuos.wordpress.com/2011/01/06/smuos-and-the-srr-framework/">http://smuos.wordpress.com/2011/01/06/smuos-and-the-srr-framework/</A><BR>The
project at: <A
href="http://sourceforge.net/projects/simulrr">http://sourceforge.net/projects/simulrr</A><BR><BR>This
playground could be used by others interested, too.<BR><BR>I know the
sourceforge project has still a lot of weaknesses (poor chat, poor GUI,
written entirely in ECMAScript, uses currently only one multiuser
server......), but I decided to post NOW at X3D-Public, because NOW we have a
lot of discussions regarding "doing things within the scene" or "doing things
outside the scene" (because of the declarative 3D discussion) and it fits
here.<BR><BR>It's a private hobby project and I am not backed by a company,
but it *could* become a topic for my employer.<BR><BR>Have fun<BR>Christoph
