[vtkusers] Probing points

[Aurélien Marsan]

Hi again,

I order to navigate through the blocks of the MultiBlockDataSet, you should
use the *GetBlock* function.

For your second question : there is such a function.
It is called vtkAppendFilter. (see
http://www.vtk.org/doc/release/5.6/html/a00125.html)

It returns an UnstructuredGrid, that you can probe using the probe filter.

Here agin, you should iterate through the blocks of the MultiBlocks in order
to append each block as input of the AppendFilter.
