Detailed Description

This class implements a trivial mapping defined by

\[ \bar{x} = x + c_1 \]

\[ \bar{y} = y + c_2 \]

\[ \bar{z} = z + c_3 \]

where \(c_i\) are constants, \((\bar{x},\bar{y},\bar{z})\) are the Cartesian (physical) coordinates and \((x,y,z)\) are the transformed (computational) coordinates.
