Hi, thank you for reply. I googled and found out any example about this. but, I have a doubt about osg::AutoTransform: I saw this get the position by a Vec3 but circleNode get his position by GeoPosition:
Assuming this: osg::AutoTrasform at = new .... at->pos( Vec3 ) CircleNode myCircle = new CircleNode(.... GeoPosition(lat/lon) .... ); ..... at->addChild(myCircle) 1. What are represent the values I set up in Vec3 in terms of position? (lat/lon, coordinates or other??) 2. GeoPosition get lat/lon but if I have already set up Vec3 position for "at" which is going to position he choose to draw? The last: Now, thanks annotation callback I receive my circle node and his AnnotationData I defined. I saw AutoTrasform doesn't have setAnnotationData. If I do at->addChild(myCircleNode) and group->addChild(at) I aspect to receive "at" as Annotation (is it correct??). How can I extract any AnnotationData by this? Many Thank [quote="Trajce Nikolov NICK"]you can use osg::AutoTransform on top of your circle ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68148#68148 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
