'''Texture''' in [http://en.wikipedia.org/wiki/Materials_science Materials Science] is the distribution of crystallographic orientations of a [http://en.wikipedia.org/wiki/Polycrystalline polycrystalline sample]. A sample in which these orientations are fully [[random]] is said to have no texture. If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak, moderate or strong texture. The degree is dependent on the percentage of crystals having the preferred orientation. Texture is seen in almost all engineered [[material]]s, and can have a great [[influence]] on [[material]] properties. Also, geologic rocks show texture due to their thermo-[[mechanic]] history of formation [[processes]].
One extreme case is a complete lack of texture: a solid with perfectly [[random]] crystallite orientation will have [http://en.wikipedia.org/wiki/Isotropic isotropic] properties at length scales sufficiently larger than the size of the crystallites. The opposite extreme is a perfect single crystal, which has [http://en.wikipedia.org/wiki/Anisotropic anisotropic] properties by [[Geometry|geometric]] [[necessity]].[http://en.wikipedia.org/wiki/Texture_(crystalline)]
