Dear Abid,
Could you specify what mean by 3D or 2D.
The plot you attach plots one component of Berry curvature as a function of
2components of k vector. Such plots should be possible with kslice module.
If you need to tabulate the Berry curvature across the 3D Brillouin zone,
you may try the WannierBerri package, see wannier-berri.org

Stepan Tsirkin,
