Detailed Description

Represents Shape node instances.

Constructor & Destructor Documentation

Shape (  const NodeType &    nodeType, const ScopePtr &    scope )

Constructor. Parameters: nodeType  the NodeType associated with the node. scope  the Scope to which the node belongs.

~Shape (    )  throw () [virtual]

Destructor.

Member Function Documentation

const BVolume * getBVolume (    )  const [virtual]

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

bool isModified (    )  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 Node.

void processSet_appearance (  const FieldValue &    sfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_appearance eventIn handler. Parameters: sfnode  an SFNode value. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

void processSet_geometry (  const FieldValue &    sfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_geometry eventIn handler. Parameters: sfnode  an SFNode value. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

void render (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

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

void updateModified (  NodePath &    path, int    flags )  [virtual]

Propagate the bvolume dirty flag from children to parents. Parameters: path  stack of ancestor nodes. flags  1 indicates normal modified flag, 2 indicates the bvolume dirty flag, 3 indicates both. Reimplemented from Node.

Member Data Documentation

SFNode appearance [private]

appearance exposedField.

SFNode geometry [private]

geometry exposedField.

Viewer::Object 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.
