openvrml::vrml97_node::group_node::group_node | ( | const node_type & | type, | |
const boost::shared_ptr< openvrml::scope > & | scope | |||
) |
Construct.
type | the node_type associated with the node. | |
scope | the scope to which the node belongs. |
openvrml::vrml97_node::group_node::~group_node | ( | ) | throw () [virtual] |
Destroy.
const bounding_volume & openvrml::vrml97_node::group_node::bounding_volume | ( | ) | const [virtual] |

bool openvrml::vrml97_node::group_node::modified | ( | ) | const [virtual] |
Determine whether the node has been modified.
true
if the node or one of its children has been modified, false
otherwise. Reimplemented from openvrml::node.
Reimplemented in openvrml::vrml97_node::collision_node.
