  | type | the node_type associated with the node.
  | scope | the scope to which the node belongs.

openvrml::vrml97_node::point_set_node::~point_set_node | ( |  | ) | throw ()`[virtual]`

| Destroy.

## Member Function Documentation

bool openvrml::vrml97_node::point_set_node::modified | ( |  | ) | const`[virtual]`

Determine whether the node has been modified.

Returns:
  `true` if the node or one of its children has been modified, `false` otherwise.

Reimplemented from openvrml::node.

const bounding_volume & openvrml::vrml97_node::point_set_node::bounding_volume | ( |  | ) | const`[virtual]`

Get the bounding volume.

Returns:
  the bounding volume associated with the node.

Reimplemented from openvrml::node.

viewer::object_t openvrml::vrml97_node::point_set_node::do_render_geometry | ( | openvrml::viewer & | viewer,
|  | rendering_context | context
| ) | `[private, virtual]`

Insert this geometry into `viewer's` display list.

Parameters:

  | viewer | a Viewer.
  | context | the rendering context.

Reimplemented from openvrml::geometry_node.

bool openvrml::vrml97_node::point_set_node::do_emissive | ( |  | ) | const throw ()`[private, virtual]`

Indicate that point sets should be drawn with the emissive color.

Returns:
  `true`.

Reimplemented from openvrml::geometry_node.

void openvrml::vrml97_node::point_set_node::recalcBSphere | ( |  | ) | `[private]`
