Hi community,

I am trying to open a vtk file in 3DSlicer. I open it as Model, and then in the Model module I try to visualize it but I can not see anything.

In Paraview I have to visualize it as Point Gaussian.

Can you help me visualizing it?

This is the files that I am trying to open:

This is an unstructured grid with points but no cells. We don’t have a rendering mode for that by default because it hasn’t come up before or at least not offen enough for someone to add a mode. You can use vtk filters to add cells or create a polydata with glyphs at the points, whatever make sense for your use case.

If you find something useful it could be added to the models displayable manager to handle this case.
