Hi All,
I'm sorry but there are several details related to this task.
One more problem. Just to summarize the code status. I implemented a track view
object as a view of a composite viewer. I set an osg::PositionAttitudeTransform
node as scene data of the view. I then read an obj of thetrack

to disable mouse intaraction I used:

Does it make sense? Is there a better way?

Hi Nick,
I'm not sure the point is the type of node used. I try to explain in detail.
Basically I would like to use the same sub-scene that represents my moving
object both on the main 3D view and on the track map.
A moving object is insert in the scene of the main view. It can be scaled and
Hi Gianni,
so as I understand you you have one scene but you want to have a different
representationsof the objects from the main scene into the map scene. I
would do it with updateCallback. Let say you have a car that
MatrixTransfrom is moving in the main scene. And you want icon in the map

Yes Nick, that's correct. Thanks for the suggested implementation.

Here I am again ...
Every moving object is something like this:
osg::PositionAttitudeTransform (for trasnformations wrt global)
osg::PositionAttitudeTransform (for scaling underlying graphics, not
transformations)
osg::Group (that contains real graphics)
As suggested, the track map is
Hi Gianni,
I never used PositionAttitudeTransform. Try MatrixTransform instead. You
can combine different transformation in the final Matrix. Something like:
osg::MatrixTransform* mxt = new osg::MatrixTransform;
mxt-setMatrix(osg::Matrix::scale(x,y,z)*osg::Matrix::translate(x,y,z))

Hi,
since my track objcts are now osgViewer::View, what should I do to clone a

way the camera manipulator is not copied. A camera manipulator itself doesn't
have a clone method and since a view can have a camera

what do you mean by cloning a View? Clone the View structure or clone what
is in it displayed? If later you just share the scene across multiple
views, put the same node in setSceneData()

Hi All,
just a couple of questions.
I would like drag the view just like I can do with osgWidgets.
At the moment I used an OrbitManipulator for each view but I really don't need
a manipulator for that view. But vithout a manipulator I can't see anything.
Thanks for your help,
Gianni

Thanks Robert. How could I overlap the two views? Looking at osgcompositeviewer
example it seems they can overlay but one rectangle hides others while I need
the 2D teack background to be transparent.

Hi Robert,
there's just one thing I don't like of this approach: the viewer is the driver.
In my application I have one scene and I attach the root node to the viewer at
startup. Then every model (xml) I load builds its own osg sub-graph and is
attached to the scene. So that code doesn't need

Thank you again Robert!
If I undarstand correctly, then I have to create a composite viewer with a
proper view for a 2D track even if the user may not need it (i.e. 2D track
object not loaded). That would not be a real problem.
But on the other hand a user can load more then one 2D track object

A CompositeViewer with two View's, potentially sharing the same window so
that one view overlays the other like a HUD is the way I would tackle the

I'm not sure I've understood you fully, but maybe a HUD is enough to suit

I have solved this in the past with composite viewer. It's up to you what
you put in your views, like, the 2D view can have ortho and rendering

what Jordi suggested with hud display

Thanks Jordi and Nick for the replay.
I thought of a HUD but I didn't investigate if a hud can be dragged or resized.
If so then that's will be fine.
I'm attaching an image to show what I need. Just consider that the 2D track and
3D scene can be overlapped.
Hope this is clearer.
Regards
You can use HUD for this. It will work better with resizing then the
comosite viewer with views. In any case you will have a separate
osg::Camera that for the HUD case will render to texture and apply to
osg::Geometry. This is very simple task. Have a look at the hud sample,
osgprerender for
Thanks Nick,
I already implemented a HUD for 3D axes but whithout resizing and dragging.
Anyway thanks again for the hint.

Hi All,
I have a scene with moving objects (basically cars) in a 3D view and a fixed
object (i.e. the track). Now I need to show a simplified track (just the
centerline of the track, coming from a separate graphic file, if needed) in one
corner of the 3D viewer with runnig cars as simple
