hi, as far as i understand every Drawable object in the scenegraph does have a "_boundingBox" data member.
* does the user have to manually initalize this boundingBox (with a call like "myDrawableOject.computeBound()"), or has it already been set by osg to nodes' geometry extent (xmin, xmax, ymin, ymax, zmin, zmax)? * if the user wants to query, if a ceratin vec3 position lies inside a Drawable object, can this be done with something like: "myDrawableObject.getBound().contains(osg::Vec3f(...))"? * if the user has a non-rectangluar polygon (e.g. an area in form of pentagram), will the above also work? if not, can you give me a hint how to implement an adequate contains()-query? thanks in advance, christian ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8153#8153 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
