Normally you don't need to do this, as any parent Transforms take care of this
automatically. But sometimes you do need to do it. OSG does it in
Transform::computeBound, so you could copy that code.
But as it turns out I've already done that for you. The svn trunk of osgWorks
(osgworks.googlecode.com) contains a utility function for performing this task,
based on the code in Trancform.cpp:
namespace osgwTools {
osg::BoundingSphere transform( const osg::Matrix& m, const
osg::BoundingSphere& sphere )
}
The osgWorks header for this is: #include <osgwTools/Transform.h>
