I have a Brain MRI dataset which I cut into halp using a clipPolyData Class.<br> Since I cut off from the medial plane. THere is a hole where the cut is made and I can look in the interior. I want to fill up this hole with a fake surface.<br> <br> What will be the best method to do that ..<br> <br> Currently I am trying to do this . But I doesnt work for me.<br> <br> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="Generator" content="Kate, the KDE Advanced Text Editor"> <pre>vtkPolyDataNormals *normals = vtkPolyDataNormals::New(); normals->SetInput(leftMRI); vtkClipPolyData *clipData = vtkClipPolyData::New(); clipData->SetInput(normals->GetOutput()); clipData->SetClipFunction(yzPlane); clipData->GenerateClipScalarsOn(); clipData->GenerateClippedOutputOn(); clipData->SetValue(<span style="color: rgb(0, 0, 255);">0</span>); clipData->Update(); vtkCutter *cut = vtkCutter::New();
