## Detailed Description

Abstract base class for geometry nodes.

## Constructor & Destructor Documentation

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

Destroy.

openvrml::geometry_node::geometry_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

void openvrml::geometry_node::render_geometry | ( | viewer & | v,
|  | rendering_context | context
| ) |  |

Insert geometry into a viewer.

Parameters:

  [in,out] | v | viewer.
  [in] | context | rendering context.

bool openvrml::geometry_node::emissive | ( |  | ) | const throw ()

Indicates whether the geometry should be drawn with the emissive color.

Returns:
  `true` if the geometry should be drawn with the emissive color; `false` otherwise (if the geometry should be drawn with the diffuse color).

const openvrml::color_node * openvrml::geometry_node::color | ( |  | ) | const throw ()

Get the color node (if any) associated with this geometry.

Returns:
  the `color_node` associated associated with this geometry, or 0 if there is no such node.

void openvrml::geometry_node::do_render_geometry | ( | viewer & | v,
|  | rendering_context | context
| ) |  | `[private, virtual]`

`render_geometry` implementation.

Parameters:

  [in,out] | v | viewer.
  [in] | context | rendering context.

bool openvrml::geometry_node::do_emissive | ( |  | ) | const throw ()`[private, virtual]`

`emissive` implementation.

Returns:
  `false`.

const openvrml::color_node * openvrml::geometry_node::do_color | ( |  | ) | const throw ()`[private, virtual]`

Get the color node (if any) associated with this geometry.

Returns:
  the `color_node` associated associated with this geometry, or 0 if there is no such node.

openvrml::geometry_node * openvrml::geometry_node::to_geometry | ( |  | ) | throw ()`[private, virtual]`

Cast to a `geometry_node`.

Returns:
  a pointer to this `geometry_node`.

Reimplemented from openvrml::node.
