Previous: Rotations and Quaternions
Doing rotation this way is fairly perverse, except for three points:
- For many applications, the independent definition of an
axis of rotation and an angle makes sense.
- The definition of an orientation by a quaternion is
coordinate system independent and isotropic.
- Spherical interpolation of quaternions gives better results
than interpolation of Euler angles.
