Re: [osg-users] Track map on a 3D view
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 and add as child of the position attutude transform. I update the viewport of the camera view to have width and height proportional to the track bounding box. Finally in some way I cal setViewMatrixAsLookAt() from the view camera to fit the track. Now, the problem. If I resize the window vertically I see the track resizing, while if I resize the window horizontally the track is not resized so thet it is cut (left/right) at a certain point. It seems the viewport is resized correctly. Any idea?

Re: [osg-users] Track map on a 3D view
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 its transformation matrix changes during animation. The transformation is a PositionAttitudeTransform but a MatrixTransform should work the same. The problem is now related to the fact I would like to add the root node of the sub-scene also to the root node of the track map view. That is useful since updated transformations for the moving objects are automatically reflected on the track map. That means the moving object moves correctly on the track. But the track map view is much smaller than the main view. So that, if the track graphics is fine, the moving objects on the track are too small to be seen. So I need to scale the moving object on the track map view, but without changing the scale on the 3D main view nor on the transformation that must move correctly also on the track map view.

Re: [osg-users] Track map on a 3D view
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
scene but following an object from the main scene. So let say:
main view:
MatrixTransform * mainSceneObject =
map view:
MatrixTransofrm* mapSceneObject (this one with scale but following an
object from the main scene).
you do updateCallback on the mapSceneObject where you simply copy the
matrix from the main scene for translation and use a scale, like
class FollowNodeFromMainSceneNodeCallback : public osg::NodeCallback
{
public:
FollowNodeFromMainSceneNodeCallback(osg::MatrixTransform* mxt)
: _mainSceneObject(mxt) {}
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::MatrixTransform* mapSceneObject =
dynamic_castosg::MatrixTransform*(node);
mapSceneObject-setMatrix(osg::Matrix::scale(x,y,z)*_mainSceneObject-getMatrix().getTrans());
}
protected:
osg::MatrixTransform* _mainSceneObject;
};
and you do then mapSceneObject-setUpdateCallback( new
FollowNodeFromMainSceneNodeCallback(mainSceneObject);
this way you have two MatrixTransoform for the same object across the
scenes, one following the other plus scale.

Re: [osg-users] Track map on a 3D view
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 basically an osgViewer::View with a osg::PositionAttitudeTransform as scene data.

Re: [osg-users] Track map on a 3D view
Hi Gianni, I never used PositionAttitudeTransform. Try MatrixTransform instead. You can combine different transformation in the final Matrix.

If you wanted just a single scene graph then the NodeMask/TraversalMask combination can be used to make sure each view gets to see what parts of the scene graph are of interest to it. See the osgstereoimage example for an illustration of using node masks/traversal masks (just change the traversal masks to CullMask for your purposes.)

Re: [osg-users] Track map on a 3D view
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 (even if in this case it would not have really sense). Of course a new view can be added for each 2D track object but that means my scene manager should depend on the viewer (at the moment this dependency is not needed).

Re: [osg-users] Track map on a 3D view
Hi Gianni, 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 tasks. The View's could share the same scene graph, or have their own scene graph. If you wanted to share the scene graph but view different parts of it the way to do it is use a NodeMask and Camera::CullMask combination to insure the each view traverses only the intended parts of the scene graph for that view.

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.

[osg-users] Track map on a 3D view
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 colored points. I thought of an object derived from osgWidget::Window, or simply a Camera, or both? Anything else is more appropriated? Thank you!

Re: [osg-users] Track map on a 3D view
Hi Gianni, have a look at osgcompositeviewer example. You can add another view in the corner (no need of osgWidget::Window). There is a class osgViewer::CompositeViewer and osgViewer::View. The example demonstrated how to have multiple views each with separate renderings.
