## Detailed Description

Abstract base class for transform nodes.

## Constructor & Destructor Documentation

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

Destroy.

openvrml::transform_node::transform_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 openvrml::mat4f & openvrml::transform_node::transform | ( |  | ) | const throw ()

Get the transformation associated with the `node` as a matrix.

This function delegates to `do_transform`.

Returns:
  the transformation associated with the `node`.

openvrml::transform_node * openvrml::transform_node::to_transform | ( |  | ) | throw ()`[private, virtual]`

Cast to a `transform_node`.

Returns:
  a pointer to this `transform_node`.

Reimplemented from openvrml::node.

const openvrml::mat4f & openvrml::transform_node::do_transform | ( |  | ) | const throw ()`[private, pure virtual]`

Get the transformation associated with the `node` as a matrix.

Returns:
  the transformation associated with the `node`.
