## Detailed Description

Abstract base class for normal nodes.

## Constructor & Destructor Documentation

openvrml::normal_node::~normal_node | ( |  | ) | throw ()`[pure virtual]`

Destroy.

openvrml::normal_node::normal_node | ( | const node_type & | type,
|  | const boost::shared_ptr< openvrml::scope > & | scope |
| ) |  |  | throw ()`[protected]`

Construct.

Parameters:

  `[in]` | type | the `node_type` associated with the node.
  `[in]` | scope | the `scope` the node belongs to.

## Member Function Documentation

const std::vector< openvrml::vec3f > & openvrml::normal_node::vector | ( |  | ) | const throw ()

Get the array of normal vectors.

This function delegates to `do_vector`.

Returns:
  the array of normal vectors.

openvrml::normal_node * openvrml::normal_node::to_normal | ( |  | ) | throw ()`[private, virtual]`

Cast to a `normal_node`.

Returns:
  a pointer to this `normal_node`.

Reimplemented from openvrml::node.

const std::vector< openvrml::vec3f > & openvrml::normal_node::do_vector | ( |  | ) | const throw ()`[private, pure virtual]`

Get the array of normal vectors.

Returns:
  the array of normal vectors.
