The particular rotation sequence is specified via the enumeration:
//- Euler-angle rotation sequence
enum rotationSequence
{
ZYX, ZYZ, ZXY, ZXZ, YXZ, YXY, YZX, YZY, XYZ, XYX, XZY, XZX
};
and provided as an argument to the constructor from Euler-angles
//- Construct a quaternion given the three Euler angles:
inline quaternion
(
const rotationSequence rs,
const vector& angles
);
and conversion to Euler-angles:
//- Return a vector of euler angles corresponding to the
// specified rotation sequence
inline vector eulerAngles(const rotationSequence rs) const;
