    Specifying Points, Directions, and Planes in a Unit Cell

    • Point positions, crystallographic directions, and crystallographic planes within a unit cell are specified using a coordinate system.

    • Index values for point locations, directions, and planes are determined using a right-handed coordinate system.

    • The position of any point within a unit cell is specified in terms of its fractional coordinates relative to the unit cell dimensions (x, y, z). Each coordinate value ranges from 0 to 1.

    • The right-handed coordinate system consists of three axes (x, y, z) that intersect at the origin (0,0,0) of the unit cell. The axes are mutually perpendicular.

    • Point positions within a unit cell are described by coordinates expressed as fractions of the unit cell edge lengths along each of the three axes.
