maskPoints1->SetInput(polyData1);<br> maskPoints1->GenerateVerticesOn();<br> <br><br>vtkPolyDataMapper *map1 = vtkPolyDataMapper::New();<br> map1->SetLookupTable(lut);<br> map1->SetInput(maskPoints1->GetOutput());<br> map1->ScalarVisibilityOn();<br> map1->SetScalarRange(-50,50);<br> <br> <br> vtkActor* actor1 = vtkActor::New();<br> actor1->SetMapper(map1);<br></div></div><br>
