A method of HSVDirectionKey.

the colours of directions under the key; MATLAB’s HSVDirectionKey/direction2color

Syntax

rgb = key.direction2color(h)

The colours of crystal directions.

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

One saturation for every direction.

Description

Each direction is brought into the sector, then into the white half, the fold telling which of the two centres its colours run from, and coloured by the colour sphere (sphereColor) with the key’s grayValue, grayGradient and colorStretching. A sharp key (a finite maxAngle) instead brings each to the equivalent nearest the white centre and reads the radius off the angle to it. Directions of zero or undefined length are black.

Input

h vector3d or Miller, the directions

Keywords

keyword default description
gray None the saturation of every direction, in [0, 1], instead of the fading towards the centres; MATLAB’s option grayValue

Output

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