Rotate ideal SC, BCC, and FCC unit cells while lattice geometry, packing fraction, coordination, atoms per cell, lattice parameter, and selected-site distances remain tied to one crystal state.
3D scene
Ideal cubic hard-sphere lattice coordinates expressed in nm. View fitting changes only display scale and does not alter lattice distances.
Site measurement
0.35355 nm
corner-0 → corner-1
Geometry relation
a = 0.35355 nm
The unit-cell coordinates span 0 → a along each Cartesian axis. The lattice parameter is calculated from the selected ideal hard-sphere contact relation for FCC.

Scientific boundary
Ideal SC/BCC/FCC cubic hard-sphere geometry only. Defects, thermal motion, anisotropy, chemistry-specific radii, non-cubic structures, polymorphism, and electronic structure remain outside this model.
