Isosurfaces in 3D subsurface model

Hey guys,

I am currently working on my thesis. That being said, I am trying to visualize a 3D-subsurface model which I have a csv.-File for.
My Problem: so far I did only tried using the Filters “Table to Points”, “3D-Delauney” and “Table to Surface”, but my goal ist to visualize isosurfaces within the subsurface model? How can I create surfaces which depend on the Properties of my Points? I should add that I could only visualize the model as points using the “Table to Points” filter. Also I can not render volumes because I don’t have blocks.

I am very new to Paraview, so if my question is not understandable or not possible, I do apologize.
