Hello,<br><br>I have to display contours, for a given range, by mapping values to colours. i.e. Consider I need to display contours between 1 and 200.<br><br>I use the lookuptable as follows<br><br>vtkSmartPointer<vtkLookupTable> lut = vtkSmartPointer<vtkLookupTable>::New();<br>
<div id=":5k">lut->SetNumberOfTableValues(9);<br>lut->SetTableValue(0, 1.00, 0.00, 0.00);<br>
lut->SetTableValue(1, 1.00, 0.50, 0.00);<br>lut->SetTableValue(2, 1.00, 1.00, 0.00);<br>lut->SetTableValue(3, 0.50, 1.00, 0.00);<br>
lut->SetTableValue(4, 0.00, 1.00, 0.00);<br>
lut->SetTableValue(5, 0.00, 1.00, 0.50);<br>lut->SetTableValue(6, 0.00, 1.00, 1.00);<br>
lut->SetTableValue(7, 0.00, 0.50, 1.00);<br>
lut->SetTableValue(8, 0.00, 0.00, 1.00);<br>lut->Build();</div><br>Now suppose I want the output like show below<br><br>01 - 10 ==== (1.0, 0.0, 0.0)<br>11 - 20 ==== (1.0, 0.5, 0.0)<br>21 - 30 ==== (1.0, 1.0, 0.0)<br>
31 - 40 ==== (0.5, 1.0, 0.0)<br>
41 - 50 ==== (0.0, 1.0, 0.0)<br>
51 - 60 ==== (0.0, 1.0, 0.5)<br>61 - 80 ==== (0.0, 1.0, 1.0)<br>
81 - 100 ==== (0.0, 0.5, 1.0)<br>
101 - 200 ==== (0.0, 0.0, 1.0)<br><br>How can this be done.?? So that the values supplied should be mapped to the corresponding colour and should be displayed.<br><br>Thanks<br><br>Regards<br>Rakesh Patil<br>
