Abstract base class for child nodes.
| openvrml::child_node::~child_node | ( | ) | throw () [pure virtual] |
Destructor.
| openvrml::child_node::child_node | ( | const node_type & | type, |
| const boost::shared_ptr< openvrml::scope > & | scope | ||
| ) | throw () [protected] |
Constructor.
| [in] | type | the node_type associated with the node. |
| [in] | scope | the scope the node belongs to. |
| void openvrml::child_node::relocate | ( | ) | throw ( std::bad_alloc ) |
Called when the node is relocated to a new position in the scene graph.
This function delegates to the virtual function do_relocate. relocate should be called by eventIn handlers that receive nodes.
| std::bad_alloc | if memory allocation fails. |
| void openvrml::child_node::render_child | ( | viewer & | v, |
| rendering_context | context | ||
| ) |
Render the node.
This function delegates to do_render_child.
| [in,out] | v | viewer implementation responsible for actually doing the drawing. |
| [in] | context | generic context argument; holds things like the accumulated modelview transform. |
| openvrml::child_node * openvrml::child_node::to_child | ( | ) | throw () [private, virtual] |
| void openvrml::child_node::do_relocate | ( | ) | throw ( std::bad_alloc ) [private, virtual] |
child_node subclass-specific relocation update.
This method is called by relocate. Subclasses of child_node should override this function for any subclass-specific updates that need to be performed following relocation of a child_node to a new position in the scene graph (for example, updating a node_path).
The default implementation of this method does nothing.
| void openvrml::child_node::do_render_child | ( | viewer & | v, |
| rendering_context | context | ||
| ) | [private, virtual] |
render_child implementation.
Rendered child_nodes should override this method.
| [in,out] | v | viewer implementation responsible for actually doing the drawing. |
| [in] | context | generic context argument; holds things like the accumulated modelview transform. |
Reimplemented in openvrml::script_node.
