A schematic of the concept of the R3DVS descriptors. (a) A continuous, field quantity s(r) in a solid and (b) its Fourier coefficient s(g) in the reciprocal lattice space. (c) The discretised function s r and (d) the corresponding Fourier’s coefficients s g. (e) The s g values are hollowed out with a radius g cut from g = 0 origin, and (d) the voxel values are rearranged on a new cubic meshes, which are defined by parameters δL* and L* (see the main texts).
