// .NAME vtkAssemblyPath - a list of nodes that form an assembly path
// .SECTION Description
// vtkAssemblyPath represents an ordered list of assembly nodes that
// represent a fully evaluated assembly path. This class is used primarily
// for picking. Note that the use of this class is to add one or more
// assembly nodes to form the path. (An assembly node consists of an instance
// of vtkProp and vtkMatrix4x4, the matrix may be NULL.) As each node is
// added, the matrices are concatenated to create a final, evaluated matrix.

// pointer m may be NULL. Note: that matrix is the one,
// if any, associated with the prop.
void AddNode(vtkProp *p, vtkMatrix4x4 *m);
// Description:
// Get the next assembly node in the list. The node returned
// contains a pointer to a prop and a 4x4 matrix. The matrix
// is evaluated based on the preceding assembly hierarchy
// (i.e., the matrix is not necessarily as the same as the
// one that was added with AddNode() because of the
// concatenation of matrices in the assembly hierarchy).

// Description:
// Get the first assembly node in the list. See the comments for
// GetNextNode() regarding the contents of the returned node. (Note: This
// node corresponds to the vtkProp associated with the vtkRenderer.
