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

appearance exposedField.

geometry exposedField.

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.
