Webbthe crystallographic unit cell are given. The unit cell is given by the length of the three axes, a, b and c (unit cell dimensions, unit cell parameters, cell edges; i.e. the lengths of the vectors t1, t2 and t3) and the angles α, β and γ. Definition of the angles relative to the axes (t1, t2 and t3 or equivalent a, b and c) is shown in ... In transformation geometry, the elemental concept of transformation is the reflection (mathematics). In planar transformations a translation is obtained by reflection in parallel lines, and rotation is obtained by reflection in a pair of intersecting lines. To produce a screw transformation from similar concepts one must use planes in space: the parallel planes must be perpendicular to the screw axis, which is the line of intersection of the intersecting planes that ge…
