This interactive simulation allows one to recreate the examples shown in the stacking fault section of this tutorial. The probabilities alpha and beta control the stacking sequence of the a, b and c layers. Refer to the stacking fault section for definitions.

The simulated crystal consists of 50 layers, each layer is made up of 50 identical atoms. The only difference between the layers is a shift of 1/3 along the x-axis. The underlying metric assumes the cubic structure and the reciprocal lattice units used for the diffraction pattern reflect this metric.

In contrast to the pictures in the stacking fault section, the different layers are shown in different colors in the simulation result picture.
