Figure 3
(a) Equilateral calcite rhombohedron with {104} faceting; (b) power spectrum of such a crystal in isointensity surface representation; (c) isointensity surface representation of small-angle scattering on sea urchin spine – tails are pointing towards 104 spots. Real space and reciprocal space scales are arbitrary and frame orientation is selected to be the same.
