[vtkusers] vtkPointPicker with multiple datasets/actors/mappers

[Ben Held]

Hi,

I have a view in which I am displaying vector field and a finite element
mesh as separate datasets/actors/mappers.  I want to be able to pick points
and retrieve field values.  When I do this using vtkPointPicker, I seem go
get either the dataset associated with the mesh or with the vector fields
(using pPicker->GetDataSet()).  I want to somehow define the order in which
vtkPointPicker checks for picks so that I can insure that I get the vector
field data.  Is this possible?

Thanks,
Ben
