How to add a MRML node into the scene ?
- Generic pattern
vtkNew<vtkMRML???Node> nodeToAdd;
...
mrmlScene->AddNode(nodeToAdd.GetPointer());
- Add a polydata to the scene
vtkNew<vtkMRMLModelNode> modelNode;
modelNode->SetPolyData(polyData);
mrmlScene->AddNode(modelNode.GetPointer());
- Load a polyData from file
vtkSlicerModelsLogic* modelsLogic = ...;
//modelsLogic->SetMRMLScene(mrmlScene);
modelsLogic->AddModel(polyDataFileName);
What to do if you get 'No LookupTable was set but number of components in input doesn't match OutputFormat' when loading a MRML scene ?
If you get the following error messages:
ERROR: In /path/to/VTK/Imaging/vtkImageMapToColors.cxx, line 153 vtkImageMapToColors (0x268f190): RequestInformation: No LookupTable was set but number of components in input doesn't match OutputFormat, therefore input can't be passed through! ERROR: In /path/to/VTK/Imaging/vtkImageExtractComponents.cxx, line 239 vtkImageExtractComponents (0x26947e0): Execute: Component 1 is not in input. ERROR: In /path/to/VTK/Imaging/vtkImageExtractComponents.cxx, line 239 vtkImageExtractComponents (0x26947e0): Execute: Component 1 is not in input. [...]
Make sure the colorNodeRef attribute is set on each VolumeDisplay node.
