Hello,

I used a vtkLookUpTable to color a vtkPolyData like this :

vtkSmartPointer<vtkPolyData> surface = m_optimizations.at(i).m_map->getShape();

 // set the lookup table (allows to draw each vertex with its own color, according to the table of values resulting from the occlusion filter)
 vtkLookupTable *vtkLUT = vtkLookupTable::New();
 vtkLUT->SetTableRange(0.0, 255.0);
 vtkLUT->SetNumberOfTableValues(26);
 vtkLUT->SetTableValue(0, 0.0, 0.5, 1.0, 1); // blue
 vtkLUT->SetTableValue(1, 0.0, 0.8, 0.5, 1); // green
 vtkLUT->SetTableValue(2, 0.0, 1.0, 0.0, 1); // green
 vtkLUT->SetTableValue(3, 0.0, 1.0, 0.0, 1); // green
 vtkLUT->SetTableValue(4, 0.2, 1.0, 0.0, 1); // green-yellow
 vtkLUT->SetTableValue(5, 0.2, 1.0, 0.0, 1); // green-yellow
 vtkLUT->SetTableValue(6, 0.5, 1.0, 0.0, 1); // yellow-green
 vtkLUT->SetTableValue(7, 0.8, 1.0, 0.0, 1); // yellow-green
 vtkLUT->SetTableValue(8, 0.5, 1.0, 0.0, 1); // yellow-green
 vtkLUT->SetTableValue(9, 0.8, 1.0, 0.0, 1); // yellow-green
 vtkLUT->SetTableValue(10, 1.0, 1.0, 0.0, 1); // yellow
 vtkLUT->SetTableValue(11, 1.0, 1.0, 0.0, 1); // yellow
 vtkLUT->SetTableValue(12, 1.0, 0.8, 0.3, 1); // yellow-orange
 vtkLUT->SetTableValue(13, 1.0, 0.8, 0.3, 1); // yellow-orange
 vtkLUT->SetTableValue(14, 1.0, 0.5, 0.0, 1); // orange
 vtkLUT->SetTableValue(15, 1.0, 0.5, 0.0, 1); // orange
 vtkLUT->SetTableValue(16, 1.0, 0.2, 0.0, 1); // dark orange
 vtkLUT->SetTableValue(17, 1.0, 0.2, 0.0, 1); // dark orange
 vtkLUT->SetTableValue(18, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(19, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(20, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(21, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(22, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(23, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(24, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->SetTableValue(25, 1.0, 0.0, 0.0, 1); // red
 vtkLUT->Build();

 surface->GetPointData()->GetScalars()->SetLookupTable(vtkLUT);

But this message is appeared regularly :

Bad table range: [0, -1]

Can you help me to solve this problem, please ?

Thank you.

Why do you do this? What would you like to achieve? Normally in Slicer you use MRML color node to set up color mapping for models.

Thank you for this solution.
