A method of spotDirectionKey.

the colours of directions under the spot key

Syntax

rgb = key.direction2color(h)

The colours of crystal directions.

rgb = key.direction2color(h, gray=0.5)

Less saturated.

Description

Every direction starts white and is multiplied, for every centre, by the colour of the centre faded with the kernel psi of the angle to the nearest equivalent of the centre: the full colour at a centre, white far from all.

Input

h vector3d or Miller, the directions

Keywords

keyword default description
gray None the saturation, in [0, 1], one for all directions or one each, by default 1: a factor on the weight every centre’s colour has

Output

rgb an array of shape h.shape + (3,), RGB values in [0, 1]
