[vtkusers] vtk data

[ya ya]

Hi, all. Recently my tutor wants me to convert the discrete points into vtk 
data format, including vtkStructuredPoints, vtkRectilinearGrid, 
vtkStructuredGrid, vtkPolyData and vtkUnstructuredGrid. The discrete points 
refer to the files which just contain the coordinate value, in the form of 
(x, y, z) .I’ve read a lot of referances such as vtk User Guide and vtk 
Textbook, now I find that I can convert the discrete points into 
vtkPolyData with the Delauney triangulation algorithm, and I can also 
convert these points into vtkStructuredPoints with interpolation algorithm 
.But I have no idea how I convert these discrete points to the other three 
data format, such as vtkRectilinearGrid, vtkStructuredGrid, and 
vtkUnstructuredGrid? Please help me, I’ve been in a loss for a long time. 
Thanks very much!!


                                                                            
        Ivy
