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]

[in]scopethe 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]vviewer.
[in]contextrendering 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]vviewer.
[in]contextrendering 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.
