Introduction to Personality Theory,The calculation of projections of a plane onto a reference plane parallel to it can be done in a straightforward way using vectors. The utility of these calculations in this form is, first, that hand calculation is simple, and, second, that the vector equations can be easily translated into a computer program if desired.

Defining Vectors for Various Crystal Systems,There are several definitions for the basis vectors for face-centered cubic (FCC) structures and lattices. The most common uses the nonprimitive cube with axes . as shown in Figure 2.1. Conceptually, this set is the easiest to grasp, but the primitive set is essential for finding the allowed reflections.
