[Paraview] Re : Re : Multiple selections: points and cells

[R M]

So, to explain my probllem, I want to select cells and then points on a 
geometry.
No one can tell me if such a selection tool is possible ?
Otherwise, how could I contourn this problem ?

Thank you for ideas !

And if I develop a specific selection plugin.
I can see in the "VTK User'guide" book in "13.4 Selections" page 291 and here: 
http://www.kitware.com/products/html/SelectionsInVTK.html

"vtkSelection is a container class holding one or more vtk-SelectionNode  
objects. Each node contains information indicating what part of the data  is 
selected. A compound selection is interpreted as the union of the individual 
node selections.  We allow selections to consist of multiple nodes so that in 
one place  we can represent selections on multiple parts of the data. For 
example, a  selection on geometry may contain a vtkSelectionNode for both points  
and cells. Another use case is to collect selections from multiple  datasets in 
the same renderer into one place."

So, this means that it could be possible to do this ("For example, a  selection 
on geometry may contain a vtkSelectionNode for both points  and cell").

But, if it is possible, how a plugin processing a data (vtkPolyData, 
vtkUnstructuredGrid, vtkMultiBlocDataSet) on which we want to use one of the 
selection (points or cells) could have this list of selected data (points or 
Cells) ?

Thanks.

Currently, it is not possible to have cells and points selected at the
same time.
