Hi Sven-Erik<br /><br />Maybe EUR 0.02 from my side:<br /><br />You think about "multi X3D nodes and non X3D nodes like<br />CarSim interfacing Mathworks Simulink."""<br /><br />And you think about using an open protocol like one from the IETF.<br /><br />I'm not sure about the network architecture you are aiming at (would be in-<br />teresting to know), but regarding the network interface within the Web3D scene,<br />I guess you would like to use something "Network Sensor" like (something that<br />provides event distribution from one scene instance to all instances, shared<br />states that are stored on the server and can be modified/influenced by any<br />scene instance) and something for chat and avatars.<br /><br />If this is true, maybe you can take advantage of the results of my<br />experimental(!) open source project http://simulrr.sourceforge.net .<br />That open source project (currently pre-alpha and currently stopped)<br />provides some X3D prototypes that examplify a network interface<br />that is <span style="font-weight: bold;">more specific than the Network Sensor</span> and hence <span style="font-weight: bold;">more easy-to-use</span><br />yet experimental and of course it *uses* the Network Sensor. I do not only use<br />server side calculations provided by the network sensor natively, but<br />additionally I use what I call CBSS (Client Based Server Software) and an<br />arbitration mechanism that selects one scene instance to execute the CBSS.<br /><br />Hence you can implement your own "server" software without changing the server.<br /><br />I do not mean you can use those X3D prototypes unchanged (although it could<br />be an interesting challenge to join or fork the sourceforge project and<br />implement XMPP support), but maybe you find some ideas about the interfaces<br />of those X3D Prototypes that are helpful for your students.<br /><br />The X3D prototypes and the Concepts' Descriptions are licensed by an LGPL<br />so you can do derivative work without bad conscience.<br /><br />Description:<br />http://members.chello.at/christoph.valentin/concepts/000_Synopsis.pdf<br /><br />I have stopped that project for personal reasons, so you need not worry about<br />a huge amount of updates :-)<br /><br />Kind regards<br />Christoph<br /> <blockquote type="cite">

<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt;">Hi pyth7<br /><br /> Mybee you are right on it's a "Walking dead" <br /> But way alternative can you come up with on a open source network protocol suited multi X3D nodes and non X3D nodes like CarSim interfacing Mathworks Simulink.<br /> Togther forming a driver simulator.<br /> I'm just go 2 groups of students readdy to make this happend.<br /> Can be a option to in RT transfere positions, rotation,,,, and live video to handle a model car.<br /> An area of applications for this projeare are supporting car testing under arctic conditions.<br /><br /> So please tell me any optional protocol to use before we put more effort into usiing RT-XMPP for X3D space and Matworks / Simulink MU system.<br /><br /> /Sven-Erik Tiberg<br /><br /><br />
