Member Function Documentation

void openvrml::vrml97_node::fog_class::bind (  fog_node &  fog, double  timestamp )  throw (std::bad_alloc)

Push a Fog on the top of the bound node stack. Parameters: fog  the node to bind. timestamp  the current time.

const node_type_ptr openvrml::vrml97_node::fog_class::create_type (  const std::string &  id, const node_interface_set &  interfaces )  throw (unsupported_interface, std::bad_alloc) [virtual]

Create a node_type. Parameters: id  the name for the new node_type. interfaces  the interfaces for the new node_type. Returns: a node_type_ptr to a node_type capable of creating Fog nodes. Exceptions: unsupported_interface  if interfaces includes an interface not supported by fog_class. std::bad_alloc  if memory allocation fails. Implements openvrml::node_class.

bool openvrml::vrml97_node::fog_class::has_first (   )  const throw ()

Check to see if the first node has been set. This method is used by fog_node::do_initialize. Returns: true if the first node has already been set; false otherwise.

void openvrml::vrml97_node::fog_class::initialize (  openvrml::viewpoint_node *  initialViewpoint, double  timestamp )  throw () [virtual]

node_class-specific initialization. Parameters: initialViewpoint  the viewpoint_node that should be bound initially. timestamp  the current time. Reimplemented from openvrml::node_class.

void openvrml::vrml97_node::fog_class::render (  openvrml::viewer &  viewer  )  throw () [virtual]

node_class-specific rendering. Render the active Fog node. Parameters: viewer  a Viewer. Reimplemented from openvrml::node_class.

void openvrml::vrml97_node::fog_class::set_first (  fog_node &  fog  )  throw ()

Set the first Fog node in the world. The first Fog node in the world is used for the initial fog. This method is used by fog_node::do_initialize. Parameters: fog  a Fog node.

void openvrml::vrml97_node::fog_class::unbind (  fog_node &  fog, double  timestamp )  throw ()

Remove a Fog from the bound node stack. Parameters: fog  the node to unbind. timestamp  the current time.
