Detailed Description

template<typename VT>
class osg::BoundingSphereImpl< VT >

General purpose bounding sphere class for enclosing nodes/objects/vertices. Bounds internal osg::Nodes in the scene, assists in view frustum culling, etc. Similar in function to BoundingBox, it's quicker for evaluating culling but generally will not cull as aggressively because it encloses a greater volume.
