Detailed Description

Abstract base class for geometry nodes.

Constructor & Destructor Documentation

openvrml::geometry_node::~geometry_node

(

)

throw () [pure virtual]

Destroy.

Todo:

Proper resource deallocation in the viewer depends on the viewer not having been decoupled from the browser. We need to handle this better via some refcounting scheme.

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

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

Insert geometry into a viewer.

Parameters:

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

Returns:

object identifier for the inserted geometry.

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 () [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.

Todo:

Reevaluate the way the renderer visits geometry nodes; potentially eliminate this method.

openvrml::viewer::object_t 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.

Returns:

object identifier for the inserted geometry.

bool openvrml::geometry_node::do_emissive

(

)

const throw () [private, virtual]

emissive implementation.

Returns:

false.

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.
