Crystallographic direction grapher
WebCrystallographic planes and directions are most easily and commonly identified and specified using a stereographic projection (see Figures 3-6). The stereographic projection is a simple mathematical translation that projects the head of every unit vector (which defines all possible crystal directions) onto a two-dimensional graph. WebCrystallographic calculator. This page was built to translate between Miller and Miller-Bravais indices, to calculate the angle between given directions and the plane on which … Contact us.

Such a direction is commonly denoted by [ u v w] …
WebThe crystallographic symmetries of gemstones determine their optical properties. For example, isometric crystals have crystal structures highly symmetrical in all directions. As a result of this symmetry, light traveling in any direction within an isometric crystal travels at the same speed. WebThis coordinate system is based on the 3-axis Miller index, but with an extra axis which is used for hexagonal crystals. The system can indicate directions or planes, and are …
WebCrystallography: Miller Indices. Miller Indices are a symbolic vector representation for the orientation of an atomic plane in a crystal lattice and are defined as the reciprocals of the fractional intercepts which the plane makes with the crystallographic axes. The method by which indices are determined is best shown by example.
