Detailed Description

Represents Shape node instances.

Constructor & Destructor Documentation

openvrml::vrml97_node::shape_node::shape_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::shape_node::bounding_volume (   )  const [virtual]

Get the bounding volume. Returns: the bounding volume associated with the node. Reimplemented from openvrml::node.

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.

void openvrml::vrml97_node::shape_node::process_set_appearance (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_appearance 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::shape_node::process_set_geometry (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_geometry 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::shape_node::render (  openvrml::viewer &  viewer, rendering_context  context )  [virtual]

Render the node. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from openvrml::node.

Member Data Documentation

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.
