[osg-users] getting position and orientation of subobjects in Node Callback traversal
Hi, here the situation i am using using blender to make my 3d scene i represent the trees with green cubes : with names like : tree, tree.001, tree.002, etc the cessana airplanes are represented by white cubes and so on for all the repetitive scene objects next in my osg application i am using a find node callback visitor based on the name to replace the cubes with real 3d objects and put them in a pagedlod node tha problem is how to get the position,orientaion of these various objects during traversal to position the real 3d models correctelly thanks and good day -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39186#39186 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

From the visitor, you can call: osg::computeLocalToWorld( getNodePath() ) This will give you the absolute positioning matrix of the node you are visiting.
