Hello, <br><br>I need to display the filled contour of a particular parameter. The data contains few NAN values. Following is the code what I have written:<br><br>vtkGeometryFilter *gf = vtkGeometryFilter::New();<br>gf->SetInput(uGrid);<br>gf->Update();<br><br>vtkClipPolyData *clip = vtkClipPolyData::New();<br>clip->SetInputConnection ( gf->GetOutputPort());<br>clip->SetValue( vtkMath::Nan());<br>clip->Update();<br><br>vtkDataSetSurfaceFilter *surfaceFilter = vtkDataSetSurfaceFilter::New();<br>surfaceFilter->SetInputConnection( clip->GetOutputPort());<br><br>vtkPolyDataMapper *surfacemapper = vtkPolyDataMapper::New();<br>surfacemapper->SetInputConnection( surfaceFilter->GetOutputPort());<br>surfacemapper->SetLookupTable(mLookupTable);<br><br>vtkActor *surfaceActor = vtkActor::New();<br>surfaceActor->SetMapper( surfacemapper);<br><br>pRenderer->AddActor(surfaceActor);<br><br>Now when I render this, wherever there exists a block of land, t
hat part is being rendered, with a black shadow sort of. And this shadow seems to come from center of the screen.<br><br>How can i avoid to display this shadow..??<br><br>Thanks<br><br><br><div style="border-top:1px dashed #ccc; border-bottom:1px dashed #ccc; padding:5px;"><a href="http://mail.in.com/mails/new_reg.php?utm_source=invite&utm_medium=outgoing" style="font:13px arial; color:#1E56A1; text-decoration:none;">Dear <b>vtkusers !</b> Get Yourself a cool, short <b>@in.com</b> Email ID now!</a></div>
