<div dir="ltr">Hi all,<br><br>How to set the thresholf of vtkBandedPolyDataContourFilter?<br><br>I want to generate values form, let's say 20 to 80, so I set GenerateValues(8,20,80).<br><br>But the values less than 20 appears to be fully of same colour, I want to set this region totally transparent.<br>
<br>I tried, Mapper.setScalarRange(20,80) and also mapper.SetScalarrange(0,8), as there may be eight colours.<br><br>Whats wrong with this?<br><br>Thanks<br><br>Jothy<br></div>
