[vtkusers] color of elements out of mapper's scalarrange

[Stéphanie Prudhomme]

Hi,

I have an UnstructuredGrid and scalar values.

vtkDoubleArray var
vtkUnstructuredGrid aPolygonGrid
vtkDataSetMapper aPolygonMapper
....
    aPolygonMapper SetInput aPolygonGrid
    [aPolygonGrid GetPointData] SetScalars var
    aPolygonMapper SetScalarRange min max
....
with min > the min of var and max < the max of var


I would like points for which the value is not in the range appears in other color (not the color of the extremum of the mapper)

How can I do?

Thank a lot,
