Hi Robert,
Thank you for the response. I am still a little puzzled...shouldn't the code you refer to below set '_boundingBoxComputed' to true in addition to the current behavior of setting ‘_boundingSphereComputed’ to true? When I compare the OSG 3.0.1 version of the method to the 3.4.0 version the setting of ‘_boundingBoxComputed’ to true has been removed while the setting of ‘_boundingSphereComputed’ to true has been added. It seems that both are necessary.

The later :-) From git master: /** Get BoundingBox of Drawable. * If the BoundingBox is not up to date then its updated via an internal call to computeBond(). */ inline const BoundingBox& getBoundingBox() const { if(!_boundingSphereComputed) { _boundingBox = _initialBound; if (_computeBoundCallback.valid()) _boundingBox.expandBy(_computeBoundCallback->computeBound(*this)); else _boundingBox.expandBy(computeBoundingBox()); if(_boundingBox.valid()){ _boundingSphere.set(_boundingBox.center(), _boundingBox.radius()); } else { _boundingSphere.init(); } _boundingSphereComputed = true; } return _boundingBox; } _______________________________________________ osg-users mailing list [email protected]<mailto:[email protected]> http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
