I have a csv data organized like in the picture, with resistivity/conducivity data organized like in the enclosed picture.

I have added in my work flow a tableToPoints filter using the values in the conductivity column for the color.

(by the way, the software is not showing in the colour in the whole range of colours, regardless how I rescale the data to a custom range).
Now, as soon as I try to visualize e possibile surface as shown for instance in this video: https://www.youtube.com/watch?v=UMnIwdQhZE4
I get no result.
Is there a filter or a setting I miss ?
Thank you in advance for any explanation and you patience.

Hi Daniele,

I think you have only points but no mesh. You can try creating a mesh automatically by using Delaunay filter.

Best, Mikko

thanks mikko, for your answer. I follow your suggestion, creating first a grid of points via "table to points" filter using "resistivity" as color for points, then creating a Volume through a 3d-delaunay filter, but using the inverse value "conductivity", as shown in picture

delaunay_3d.jpg
and then a "ISOVOLUME" filter to read the geometry.


I have now just one main problem: how I get more precision in the representation ?

I guess i should interpolate the values of the table to a smaller grid,or, as an alternative, lower the tolerance in the dalaunay filter.
I have no idea how to try the first way, and I have tried the second but is still unsatisfying.
