PatalaColorKey.PatalaColorKey edit page

converts misorientations to rgb values as described in

S. Patala, J. K. Mason, and C. A. Schuh, Improved representations of misorientation information for grain boundary science and engineering, Prog. Mater. Sci., vol. 57, no. 8, pp. 1383-1425, 2012.

The color key is defined for grain exchange symmetry only, so it is always antipodal, and only for the Laue groups m-3m, m-3, mmm, 4/mmm and 6/mmm - any other symmetry raises an error.

Syntax

oM = PatalaColorKey(cs)
oM = PatalaColorKey(cs1,cs2)
rgb = oM.orientation2color(mori)

Input

cs, cs1, cs2 crystalSymmetry
mori misorientation

Output

oM PatalaColorKey
rgb list of RGB triplets

Class Properties

CS1, CS2 the two crystalSymmetry

Example

mtexdata twins
grains = calcGrains(ebsd('indexed'));
oM = PatalaColorKey(grains.boundary('Magnesium','Magnesium'))
ebsd = EBSDsquare (y↓→x, row↓→col)
