Constructor & Destructor Documentation

openvrml::vrml97_node::group_node::group_node (  const node_type &  type, const scope_ptr &  scope )

Member Function Documentation

void openvrml::vrml97_node::group_node::activate (  double  time, bool  isOver, bool  isActive, double *  p )  [virtual]

Pass on to enabled touchsensor child. Implements openvrml::grouping_node.

const bounding_volume & openvrml::vrml97_node::group_node::bounding_volume (   )  const [virtual]

Get the bounding volume. Returns: the bounding volume associated with the node. Reimplemented from openvrml::node. Reimplemented in openvrml::vrml97_node::anchor_node, and openvrml::vrml97_node::transform_node.

const std::vector< node_ptr > & openvrml::vrml97_node::group_node::children (   )  const throw () [virtual]

Get the children in the scene graph. Returns: the child nodes in the scene graph. Implements openvrml::grouping_node.

bool openvrml::vrml97_node::group_node::modified (   )  const [virtual]

Determine whether the node has been modified. Returns: 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.

void openvrml::vrml97_node::group_node::process_addChildren (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [protected]

addChildren eventIn handler. Parameters: value  an mfnode containing nodes to add to this Group. timestamp  the current timestamp Exceptions: std::bad_cast  if value is not an mfnode. std::bad_alloc  if memory allocation fails.

void openvrml::vrml97_node::group_node::process_removeChildren (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [protected]

removeChildren eventIn handler. Parameters: value  an mfnode containing nodes to remove from this Group. timestamp  the current timestamp Exceptions: std::bad_cast  if value is not an mfnode. std::bad_alloc  if memory allocation fails.

void openvrml::vrml97_node::group_node::process_set_children (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [protected]

set_children eventIn handler. Parameters: value  an mfnode containing nodes for this Group. timestamp  the current timestamp Exceptions: std::bad_cast  if value is not an mfnode. std::bad_alloc  if memory allocation fails.

void openvrml::vrml97_node::group_node::render (  openvrml::viewer &  viewer, rendering_context  context )  [virtual]

Render the node. Render each of the children. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from openvrml::node. Reimplemented in openvrml::vrml97_node::anchor_node, openvrml::vrml97_node::billboard_node, and openvrml::vrml97_node::transform_node.

void openvrml::vrml97_node::group_node::render_nocull (  openvrml::viewer &  viewer, rendering_context  context )

because children will already have done the culling, we don't need to repeat it here.
