Construct.
[in] | type | the node_type associated with the node. |
[in] | scope | the scope the node belongs to. |
const std::vector< boost::intrusive_ptr< openvrml::node > > openvrml::grouping_node::children | ( | ) | const throw ( std::bad_alloc ) |
Get the children in the scene graph.
This function delegates to do_children
.
std::bad_alloc | if memory allocation fails. |

bool | over, | ||
bool | active, | ||
const double(&) | p[3] | ||
) |
Called in response to user interaction to activate any child pointing device sensor nodes.
Calls pointing_device_sendor_node::activate
for child pointing_device_sensor_nodes
, recursively.
[in] | timestamp | the current time. |
[in] | over | whether the pointer is over sensitive geometry. |
[in] | active | whether the pointer has activated sensitive geometry. |
[in] | p | the activation point. |

grouping_node
. Reimplemented from openvrml::node.
const std::vector< boost::intrusive_ptr< openvrml::node > > openvrml::grouping_node::do_children | ( | ) | const throw ( std::bad_alloc ) [private, pure virtual] |
Get the children in the scene graph.
std::bad_alloc | if memory allocation fails. |
