Hi, I tried loading the volumetric mesh (vtkUnstructuredGrid) by using both the interface Load Data as Volume and using “slicer.util.loadVolume(’/path/to/file’)” on the Python interactor to no avail. Slicer simply doesn’t load it up. However, loading it as Model would always work. How do I load it …

Surface and volumetric meshes are represented in Slicer as model nodes. You can convert a volumetric mesh to volume by sampling the mesh at each voxel using vtkProbeFilter. Here is a complete example of how to do that: https://github.com/lassoan/SlicerNotebooks/blob/master/UnstructuredGridToVolume.i…
