Hi all I am a newer in 3D OpenSpace and need a help. First of all want to apologize for a bad english. I am make a project for education a kids for safety in road. Have some streets with buildings, traffic lights, zebra crossing. Have a girl and I track her with AR marker. I want when cam find AR marker to show girl, and when move the marker the cam follow the marker and girl walking in the streets. I appreciate any help, thank in advance.

The question is: is it possible to move object across the streets with AR marker? I tried to connect the camera to follow the object (girl) but I did not receive with AR marker. Want to be like plugIT navigation Walkthrough, but with AR marker, not by keybord, is that possible?

first some comments about graphics :
- do not user spaces or special chars in materials names or textures names
- for a scene with the same object duplicated several time, use instantiated meshes (only on mesh loaded but duplicated in the scene)
if you use 3dsMax and easy ogre exporter, just duplicate object and select instantiate.
I still don't understand what you are trying to do with AR marker ^^
if you want to move the "momiche" dummy using a marker you must first understand how markers and AR works.
If the webcam picture is shown, the virtual camera (3D view) become like this were at your real webcam position.
So the backound scene won't work.
A marker position, is the 3D position from your webcam.
So if you want to move the girl around using the marker, you will need to get the marker translation and apply it to the relative position of the girl.
Actually there is no simple way to make this ^^
I'll add the possibility to gret a marker translation and rotation for the incoming release
First you you don't need the webcam picture behind the scene, uncheck "show on start" in the AR capture plugIT

Thank you arkeon. Yes you are understand what I am want to do with AR marker. I'm a little disappointed that it is not easy to do, and probably will not be able to do with my skills. However, can you give me guidance on how to do it, if possible?

the simple way :
- add a marker with a correct scale linked to the street object
- add a marker linked to the girl with the same scale
- add a fixed camera
so you will use the main marker to position the street, and then when you will mode the girl's marker the gils will follow it correctly
I've tried translations without success, since we don't know in which direction the girl sould move

Thank you arkeon I will try this.
