[osg-users] Get all vertices of an OSG Group

I have to work on a point cloud which was stored in .osgb files for LOD management reasons. I have extracted it in an osg::Group, then this Group contains other Groups and so on.

I need to access every points of my cloud to extract coordinate or colors. I don't know if there is an easy way to do it since these are contained in osg::Drawables that are contained in osg::Geodes.

Do you know a simple way to do it ? Or do I have to explorate my first group recursivly in order to get vertices and colors arrays and to copy them in a std::map ?


Thank you!
