Member Function Documentation

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.

Returns
the children in the scene graph.
Exceptions
std::bad_allocif memory allocation fails.
void openvrml::grouping_node::activate_pointing_device_sensors ( double  timestamp,
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.

Parameters
[in]timestampthe current time.
[in]overwhether the pointer is over sensitive geometry.
[in]activewhether the pointer has activated sensitive geometry.
[in]pthe activation point.
openvrml::grouping_node * openvrml::grouping_node::to_grouping ( )
throw (
)
privatevirtual

Cast to a grouping_node.

Returns
a pointer to this grouping_node.

Reimplemented from openvrml::node.

const std::vector< boost::intrusive_ptr< openvrml::node > > openvrml::grouping_node::do_children ( ) const
throw (std::bad_alloc
)
privatepure virtual

Get the children in the scene graph.

Returns
the child nodes in the scene graph.
Exceptions
std::bad_allocif memory allocation fails.
