I’m visualising an scalar field clipped by scalar. It is stored as a unstructured grid, but it is technically a rectangular grid. When keeping everything the same and just switching between points and point gaussian representations some points do not appear. always the centre of these isolated “crosses” (see pics)

point gaussian:

I don’t understand why this is the case, and how could I make sure they are representing the same?

Should I just share the vts directly? Or is there a way to export the data plus clip operations? Sorry for the dumb questions, I’m new to paraview

the velocities are scalars because it is only their magnitudes (direction is determined by the unit normal)

You can share a state file on top.

Indeed, I reproduce.

What is happening is that the Points representation is fairly limited and show points on the surface only, while the point gaussian representation should all points, whether on the surface or not.

I can move the following to a new topic, but as it is on the same data, thought would be easier to quicky ask:

The other thing I noticed is that for both points and gaussian point, when I change the threshold value of the clip, let’s say to 1e-6, the value displayed is different, eg:  
Clip1  
Id: 33791  
Coords: (-0.0023582, 0.044474, 0.00207574)  
level\_set: 0.00020381  
unit\_normal: (-0.497853, -0.867204, 0.00662276)  
velocity: 1e-06  
velocity\_overhang: 1e-06  
velocity\_curv: 0

Clip1  
Id: 34187  
Coords: (-0.0023582, 0.044474, 0.00207574)  
level\_set: 0.00020381  
unit\_normal: (-0.497884, -0.867218, 0.00664792)  
velocity: 1e-08  
velocity\_overhang: 1e-08  
velocity\_curv: 0

They are being showed in the clip, so I assume that the value has to be at least over 1e-6, but why would the hover on point dialogue show different values? Is there a way to print the full precision valu for the fields at that point?
