Member Function Documentation

void openvrml::grouping_node::activate (  double  timestamp, bool  over, bool  active, double *  p )  [pure virtual]

Called in response to user interaction to activate any child pointing device sensor nodes. Parameters: timestamp  the current time. over  whether the pointer is over sensitive geometry. active  whether the pointer has activated sensitive geometry. p  the activation point. Implemented in openvrml::vrml97_node::group_node, openvrml::vrml97_node::inline_node, openvrml::vrml97_node::lod_node, and openvrml::vrml97_node::switch_node.

const std::vector< node_ptr > & openvrml::grouping_node::children (   )  const throw () [pure virtual]

Get the children in the scene graph. Returns: the child nodes in the scene graph. Implemented in openvrml::vrml97_node::group_node, openvrml::vrml97_node::inline_node, openvrml::vrml97_node::lod_node, and openvrml::vrml97_node::switch_node.

grouping_node * openvrml::grouping_node::to_grouping (   )  throw () [virtual]

Cast to a grouping_node. Returns: a pointer to this grouping_node. Reimplemented from openvrml::node.

const grouping_node * openvrml::grouping_node::to_grouping (   )  const throw () [virtual]

Cast to a grouping_node. Returns: a pointer to this grouping_node. Reimplemented from openvrml::node.
