Texture: an Order Parameter?
Grain Orientation Distribution in Polycrystals
Al under crossed polarizers: random top, oriented bottom

Metals are polycrystals: each grain has own orientation
Orientation given by rotation matrix R: plot probability density in rotation matrix space SO(3)/Oh
Texture matters! Roll Al, cut cylinder, squash: get ellipse.
