Member Function Documentation

bool openvrml::vrml97_node::shape_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::shape_node::bounding_volume

(

)

const [virtual]

Get the bounding volume.

Returns:

the bounding volume associated with the node.

Reimplemented from openvrml::node.

void openvrml::vrml97_node::shape_node::do_render_child	(	openvrml::viewer &	viewer,
		rendering_context	context
	)			[private, virtual]

Render the node.

Parameters:

	viewer	a viewer.
	context	a rendering context.

Reimplemented from openvrml::child_node.

Member Data Documentation

exposedfield< sfnode > openvrml::vrml97_node::shape_node::appearance_ [private]

appearance exposedField.

exposedfield< sfnode > openvrml::vrml97_node::shape_node::geometry_ [private]

geometry exposedField.

viewer::object_t openvrml::vrml97_node::shape_node::viewerObject [private]

A reference to the node's previously used rendering data.

If supported by the Viewer implementation, this member holds a reference to the node's rendering data once the node has already been rendered once. The intent is to capitalize on USE references in the VRML scene graph.
