GTGetEulerAngles
GTGetEulerAngles[symmetry element]
gives the Euler angles corresponding to a symmetry element.
DetailsDetails
- Any arbitrary rotation can be seen as a superposition of three rotations. First, a rotation by an angle about the z-axis, second a rotation by an angle about the y-axis and third a rotation by an angle about the z-axis. Thus, it can be written
- .
- The input of GTGetEulerAngles can be of type symbol, matrix, quaternion, and Euler angles.
