VTK : Generate meshes for contour data which have several curves in one contour?

Question

Greetings all,

I have stack of contours which generated using someother algorithm outside VTK. Each contour consists of several curves .

Please refer to image at :

As seen in the image, each curve has an ID to identify which level it is.(Curves in same level have identical color)

Now I want to generate Meshes using "vtkVoxelContoursToSurfaceFilter" for each of this Curve set belong. That is, one mesh for contours in Blue color , another mesh for contours in Orange color ..and so on.. And I should keep the relative positions of these Meshes. And should color each generated mesh in different color.

I keep a list of "vtkAppendPolyData" for each Curve set.

But I am not sure where I should go after this? 1.Shall I create seperate Actors for each Mesh ? If so how can I keep the relative positions of Meshes. (vtkVoxelContoursToSurfaceFilter change the origin right?) 2.Can I use vtkVoxelContoursToSurfaceFilter.SetInputConnection(int port,vtkAlgorithmOutput) and use different port number for each curves "vtkAppendPolyData".

Any tips,

thanks in advance,
