base class for assigning colours to directions with crystal symmetry

Syntax

rgb = key.direction2color(h)
key.plot()

Description

A concrete direction key maps symmetry-equivalent directions to the same colour. Colouring returns an array of shape h.shape + (3,) with RGB channels in [0, 1]. Plot the key alongside a direction or orientation map to show what its colours mean. Use HSVDirectionKey, TSLDirectionKey, HKLDirectionKey or spotDirectionKey to choose the colouring rule.

Input

CS referenceFrame or symmetry group defining equivalent directions

Properties

CS frame or symmetry supplied to the key
sym symmetry group used when folding directions
sR fundamental spherical sector used for colouring

See also

HSVDirectionKey, TSLDirectionKey, HKLDirectionKey, ipfColorKey

Members

direction2color the colours of directions, an (…, 3) array in [0, 1]
keySector a sector the key is drawn over
plot the key drawn on its sector, or with complete=True over the whole sphere
