Constructor & Destructor Documentation

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

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

~PointSet (    )  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.

Viewer::Object insertGeometry (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

Insert this geometry into viewer's display list. Parameters: viewer  a Viewer. context  the rendering context. Implements GeometryNode.

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

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

set_coord 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 recalcBSphere (    )  [private]

Recalculate the bounding volume.

void updateModified (  NodePath &    path, int    flags = 0x003 )  [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.
