20 //! Enumerates all 24 possible variants of generalized
21 //! Euler angles, defining general 3d rotation by three
22 //! rotations around main axes of coordinate system,
23 //! in different possible orders.
25 //! The name of the enumeration
26 //! corresponds to order of rotations, prefixed by type
27 //! of coordinate system used:
28 //! - Intrinsic: rotations are made around axes of rotating
29 //! coordinate system associated with the object
30 //! - Extrinsic: rotations are made around axes of fixed
31 //! (static) coordinate system
33 //! Two specific values are provided for most frequently used
34 //! conventions: classic Euler angles (intrinsic ZXZ) and
35 //! yaw-pitch-roll (intrinsic ZYX).
39 //! Classic Euler angles, alias to Intrinsic_ZXZ
42 //! Yaw Pitch Roll (or nautical) angles, alias to Intrinsic_ZYX
45 // Tait-Bryan angles (using three different axes)
60 // Proper Euler angles (using two different axes, first and third the same)
