represent a node in an assembly
a list of nodes that form an assembly path
vtkProp * TransformedProp
void AddNode(vtkAssemblyNode *n)
static vtkAssemblyPath * New()
Instantiate empty path with identify matrix.
void AddNode(vtkProp *p, vtkMatrix4x4 *m)
Convenience method adds a prop and matrix together, creating an assembly node transparently.
void ShallowCopy(vtkAssemblyPath *path)
Perform a shallow copy (reference counted) on the incoming path.
vtkMTimeType GetMTime() override
Override the standard GetMTime() to check for the modified times of the nodes in this path.
vtkAssemblyNode * GetNextNode()
Get the next assembly node in the list.
vtkAssemblyNode * GetFirstNode()
Get the first assembly node in the list.
~vtkAssemblyPath() override
vtkAssemblyNode * GetLastNode()
Get the last assembly node in the list.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkTransform * Transform
void DeleteLastNode()
Delete the last assembly node in the list.
vtkAssemblyNode * GetNextNode(vtkCollectionSimpleIterator &cookie)
Reentrant safe way to get an object in a collection.
