[vtkusers] How to do picking action with vtkCellPicker on multiples vtkDataSet?

[Leguay Romain]

Hello everyone!
I display multiple vtkDataSet on my renderer. I try to do a picking and display witch vtkDataSet I click. I try to do this with a vtkCellPicker but I can just get the selected point and the cellId.
I don't know how to proceed unless testing for each cell contains my point.
Has anyone got better ideas?

Thanks,

Romain
