[vtkusers] Problem in using vtkLookupTable with vtkContourFilter

[Jothybasu Selvaraj]

Hi all,

I am trying to use my own lookup table with vtkContourFilter, so that
it can generate contour line of my own colors.

But some of the lines are of the same color!

Here is my code

 vtkSmartPointer<vtkLookupTable> isoLineTable =
                    vtkSmartPointer<vtkLookupTable>::New();
            double
scalarMin=*std::min_element(isodoseValues.begin(),isodoseValues.end());
            double
scalarMax=*std::max_element(isodoseValues.begin(),isodoseValues.end());
            isoLineTable->SetValueRange(scalarMin,scalarMax);
            qDebug()<<scalarMin<<scalarMax;
            isoLineTable->SetNumberOfTableValues(isodoseValues.size());
           // isoLineTable->SetRampToLinear();
            isoLineTable->Build();

             for(int i=0;i<isodoseValues.size();i++)
             {
                 //qDebug()<<colorsR[i]<<colorsG[i]<<colorsB[i];

isoLineTable->SetTableValue(i,colorsR[i],colorsG[i],colorsB[i]);

             }


            vtkSmartPointer<vtkPolyDataMapper> contourMapper =
                    vtkSmartPointer<vtkPolyDataMapper>::New();
            contourMapper->SetInputConnection(cf->GetOutputPort());
            contourMapper->SetScalarRange(isoLineTable->GetRange());
            contourMapper->SetLookupTable(isoLineTable);
            contourMapper->Update();

Any suggestions?

Thanks

Jothy
