Constructor & Destructor Documentation

openvrml::vrml97_node::point_set_node::point_set_node const node_type type,
const scope_ptr scope
 

Construct.

Parameters:
type the node_type associated with the node.
scope the scope to which the node belongs.

Member Function Documentation

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::insert_geometry openvrml::viewer viewer,
rendering_context  context
[virtual]
 

Insert this geometry into viewer's display list.

Parameters:
viewer a Viewer.
context the rendering context.

Implements openvrml::geometry_node.

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.

void openvrml::vrml97_node::point_set_node::process_set_color const field_value value,
double  timestamp
throw (std::bad_cast, std::bad_alloc) [private]
 

set_color eventIn handler.

Parameters:
value an sfnode value.
timestamp the current time.
Exceptions:
std::bad_cast if value is not an sfnode.
std::bad_alloc if memory allocation fails.

void openvrml::vrml97_node::point_set_node::process_set_coord const field_value value,
double  timestamp
throw (std::bad_cast, std::bad_alloc) [private]
 

set_coord eventIn handler.

Parameters:
value an sfnode value.
timestamp the current time.
Exceptions:
std::bad_cast if value is not an sfnode.
std::bad_alloc if memory allocation fails.
