25 Foam::EulerCoordinateRotation
28 A coordinateRotation defined in the z-x-y Euler convention.
30 The 3 rotations are defined in the Euler convention
31 (around Z, around X' and around Z').
32 For reference and illustration, see
33 http://mathworld.wolfram.com/EulerAngles.html
34 Note, however, that it is the reverse transformation
35 (local->global) that is defined here.
37 - the rotation angles are in degrees, unless otherwise explictly specified:
44 rotation (0 0 3.141592654);
