Hi Paul, Thank you for your reply.
My code computes the 8 corner points of object space bounding box, called p1 , p2 , ... , p8 Then I get the first matrix transform regardless to multiparent .. i forgot to copy / paste the line : Code: osg::Matrix matrix = drawable.get->getWorldMatrices(0); Then i compute the 8 points coordinates to world space, called p1w , p2w, ... , p8w. Then i use those points to compute bottom left corner ( called minWorld ) and top right corner ( maxWorld ) points of world space bounding box, with those ugly min / max on point coordinates. It seems to work.. i m going to test your method to compare result / perf, it should be faster than my code :p Regards, Harold ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=12065#12065 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
