Isovalue

[Nayab Shiraz]

Hi

Can you please explain how to select isovalue for electron density visualization? and what does isovalue signify?
From what I understand electron density is a function of three spatial variables and hence a 3D sphere, each isovalue represents the surface of constant radius on that sphere. Please correct me if I am wrong here.

[Petr Khomyakov]

Isosurface is a surface where the value of particular quantity (e.g., electron density or whatever grid object) is constant, given by isovalue.
