Member Function Documentation

void bind (  Fog &    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 NodeTypePtr createType (  const std::string &    id, const NodeInterfaceSet &    interfaces )  throw (UnsupportedInterface, std::bad_alloc) [virtual]

Create a NodeType. Parameters: id  the name for the new NodeType. interfaces  the interfaces for the new NodeType. Returns: a NodeTypePtr to a NodeType capable of creating Fog nodes. Exceptions: UnsupportedInterface  if interfaces includes an interface not supported by FogClass. std::bad_alloc  if memory allocation fails. Implements NodeClass.

bool hasFirst (    )  const throw ()

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

void initialize (  double    timestamp )  throw () [virtual]

NodeClass-specific initialization. Parameters: timestamp  the current time. Reimplemented from NodeClass.

void render (  Viewer &    viewer )  throw () [virtual]

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

void setFirst (  Fog &    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::initializeImpl. Parameters: fog  a Fog node.

void unbind (  Fog &    fog, double    timestamp )  throw ()

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