hey...
Im a noob in python and ogre so I tried out the tutorials and I wrote my own little application and everything works fine

thanks for this funny stuff until yet!
now here is my problem: I create a XML-file (done by converter) from the cube.mesh file (source: media.zip) and now I like to rebind this file to OGRE (pyogre)
the reason for this: I try to find out, if it is possible, to visualize graph-data like the points and the edges of the cube from xml-data.
Im sure it is possible

but i dont see any solution to begin
is there somebody who can help me please? the only thread i found was this:
http://www.ogre3d.org/phpBB2addons/viewtopic.php?t=1583 but it doesn't really help
thanks for any comment and sorry for my english

hey...
Thanks for comment.
I try to visualize an object (e.g. cube) in pyogre from xml-data...
I used a converter to get the cube.xml from the cube.mesh,
so far so good
Now I want to know, how do I get the data from the created cube.xml into my pyogre application?
It seems that i have to use a parser but I dont know how to set up something like that
...but python is so much easier than c++

What data do want exactly? You can now use cube.mesh in you Ogre application. If you want to access the vertex data directory you need to do some looking through the Ogre API/Docs for hardware vertex buffers.
Thanks for comment.
I try to explain this with pictures and code...this is my
cube.xml file:

When I use the
cube.mesh file OGRE shows:
http://mitglied.lycos.de/lucywebs/pictures/cube.JPG
What I like to see is the whole wireframe but from the
cube.xml file like that:
http://mitglied.lycos.de/lucywebs/pictures/wireframe.JPG
hope this help's anyway
sorry for my incompetence to explain

Now I understand, this has very little to do with the xml format. Do you have Ogre in wireframe when you took the Ogre screenshot? It looks like you just need to make your block transparent so you can see through it to the line on the other side.
yes, OGRE was in wireframe mode...
what did I have to do, to set the sides transparent? something about material? like "RustySteel"?
and the other thing is, that I wouldn't use the cube.mesh file! what's necessary to use these data directly from cube.xml? a parser or something like that? I have no idea how to let OGRE know, that the data is coming from *xml files only (e.g. GraphML)
thanks a lot. lucy

We should take a step back here. What are you trying to do? Procedurally generate meshes for Ogre by transforming GraphML data?
yes...something like that. I try to find a way, to visualize graphs in pyOGRE and a solution to manipulate them after integration (especially from GraphML or TreeML format).
I thought that I can improve my skills by handling a wireframe and manipulate it like the facial-demo. this may sound strange to you, but this thought was the first crossing my mind
thanks

It would make more sense to procedurally generate things in python code while parsing the output. Something like the debug view for OgreNewt. That uses manually object and you can draw spheres for the nodes and lines for the edges. Investigate the manual object examples on the wiki.
thanks for all your staying power
I've got it!...creating a modell with 3dsmax9 -> convert it to xml file with 3d object converter -> transforming it into mesh with ogrecommandlinetools and launching it @ ogre
it's sad, that it seems to be necessary to convert xml back to mesh
the problem now is that I loose the information about material (colour) by using 3d object converter...but I check for other tools
