Hi Matthieu Unfortunately, OSG does not directly support what you want as osg'S bounding box, is as you have seen is a axially aligned min/max LL/UR But you could extend the example on my site http://www.3drealtimesimulation.com/osg/code/osgcode_bbox1.htm to do what you want, you will have to do extra work etc where bbox.expandBy( geode.getDrawable( i )->getBound()); you would to: change this to For every Geode get a pointer to the geoemtry, then get a pointer to the vertex array walk the vertext array extract the values you need and store them in a set of variables This data/parallelpiped you collect will only be of use to you as OSG is designed to use osg::BoundingBox etc.

You know that OSG generate BoundingBox, but it is really a box (all faces have the same size). I need the Bounding Parallelepiped of my scene. Not just the bigger radius from the center applied on each side, but the min/max coordinates on Z axis, on X axis and on Y axis individually. I have wasted some time to try myself, but I don't understand how to do that simply? I saw this example: http://www.3drealtimesimulation.com/osg/code/osgcode_bbox1.htm But it is the same problem than with OSG integrated functions. Can you help me? Thanks in advance Matthieu DIRRENBERGER
