each centre, a crystal direction, given its colour, fading to white with the kernel of the angular distance to the nearest symmetric equivalent; several centres multiply

Syntax

spotDirectionKey(cs, center=Miller(1, 1, 1, cs), color=(0, 0, 1), psi=S2DeLaValleePoussinKernel(halfwidth=7.5*degree))

Input

CS referenceFrame or symmetry defining equivalent directions
center Miller or vector3d spot centres; None selects the z direction
color one RGB triplet per centre; default red for one centre
psi spherical kernel controlling colour spread; default halfwidth 10*degree

Members

center the centres, with the equivalents under the group kept beside them
direction2color the colours of directions under the spot key
whiteCenter the first centre of the key
