Hi There
I'm trying to get colored points and tracks with a reader, but i only
get the first point colored.. can somebody please give me a hint? It
looks to me that the SetTableRange(d,d) is not doing what it's supposed
to do... (pv 3.8.0)
In position (vtkPoints) i've got 10 points, connected with lines. I
would like to color each point according to it's snapid (vtkIdTypeArray).
So, it does some coloring, but only on the line between the 1st point
(SnapId=0) and the second point (SnapId 1)..
Many thanks

My code:
-----
vtkPolyData * out = vtkPolyData::GetData(outputVector);
//...generate points...
vtkSmartPointer<vtkLookupTable> lut =
vtkSmartPointer<vtkLookupTable>::New();
lut->Build();
lut->SetTableRange(0,9);
lut->SetNumberOfTableValues(10);
lut->SetTableValue(0,1,0,0);
lut->SetTableValue(1,1,1,0);
lut->SetTableValue(2,1,1,1);
lut->SetTableValue(3,0,1,1);
//...
SnapId->SetLookupTable(lut2);
out->SetPoints(Position);
out->SetVerts(Cells);
out->SetLines(Tracks);
out->GetPointData()->AddArray(SnapId);
-----
i also tried lut->build after setting the table values, doesn't make any
difference..
