I have a Displacement field Transform and I want to visualise it only in **one** 2D view. I couldn’t find it in the UI and I couldn’t figure out how to do it in python.

Is there a way to do that?

In the **Transforms** module, first turn on “Visible in 2D view” (under _Display_ → _Visualization_) so a transform display node exists and slice visualization is enabled. Then in the Python console:

```python
transformNode = getNode("YourTransform") # or pick by ID
displayNode = transformNode.GetDisplayNode() # created when 2D vis is toggled on

# Restrict to a single slice view (e.g., Red):
displayNode.SetViewNodeIDs(["vtkMRMLSliceNodeRed"])

```

To go back to “all views”, clear the list:

```python
displayNode.RemoveAllViewNodeIDs()

```

Notes:

- The IDs for the default slice views are `vtkMRMLSliceNodeRed`, `vtkMRMLSliceNodeYellow`, `vtkMRMLSliceNodeGreen`. For a custom view, grab `sliceNode.GetID()`.
- If `GetDisplayNode()` returns `None`, call `transformNode.CreateDefaultDisplayNodes()` first, or just toggle the 2D-visible checkbox once in the Transforms module.
- This restriction also applies to the visualization region/ROI — only the listed view will render the grid/glyph/contour.

This doesn’t work for me. In which Slicer version has this worked for you? I’m in the stable release 5.10.0

1. there is no “Visible in 2D view”, I only see “Visibility:”, “Visibility in slice view:” and “Visibility in 3D view:” - I have all of them checked
2. no matter what ViewNodeIDs I set, it always remains visible in all views

I am also in 5.10 but had not tried the snippet.

(“Visibility in slice view” is the correct label, thanks)

When I tried it, indeed the grid/glyph/contour remains visible in all slice views.

It took some trickery, here is the ai generated snippet that finally worked:

```py
transformNode = getNode("YourTransform")
old = transformNode.GetDisplayNode()
if old:
    slicer.mrmlScene.RemoveNode(old)

# Create and configure the display node BEFORE attaching it to the transform.
# Until it's linked, no displayable manager will process it, so we can set
# the view filter and visibility flags safely.
dn = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLTransformDisplayNode")
dn.SetViewNodeIDs(["vtkMRMLSliceNodeRed"])
dn.SetVisibility(True)
dn.SetVisibility2D(True)
dn.SetVisibility3D(False)

# Link last — this is the moment UseDisplayNode() runs in each slice manager,
# and only the Red one will pass the IsDisplayableInView() check.
transformNode.SetAndObserveDisplayNodeID(dn.GetID())

```

The problem was that the transform 2D displayable manager is not noticing changes to the view filter. We could add to [vtkMRMLTransformsDisplayableManager2D.cxx#L149](https://github.com/Slicer/Slicer/blob/a087af0c6cb44789dcd6df06cf6291d1ecd561a2/Modules/Loadable/Transforms/MRMLDM/vtkMRMLTransformsDisplayableManager2D.cxx#L149) a `&& displayNode->IsDisplayableInView(this->SliceNode->GetID())`

Often, you can get an update to be noticed in Slicer by calling `node.Modified()`. You could try that on the transform node (or maybe the display node).
