##ANGLES3D Conventions for manipulating angles in 3D
##
##   Contrary to the plane, there are no oriented angles in 3D. Angles
##   between lines or between planes are comprised between 0 and PI.
##
##   Spherical angles
##   Spherical angles are defined by 2 angles:
##   * THETA, the colatitude, representing angle with Oz axis (between 0 and
##       PI)
##   * PHI, the azimut, representing angle with Ox axis of horizontal
##       projection of the direction (between 0 and 2*PI)
##
##   Spherical coordinates can be represented by THETA, PHI, and the
##   distance RHO to the origin.
##
##   Euler angles
##   Some functions for creating rotations use Euler angles. They follow the
##   ZYX convention in the global reference system, that is eqivalent to the
##   XYZ convention ine a local reference system. 
##   Euler angles are given by a triplet of angles [PHI THETA PSI] that
##   represents the succession of 3 rotations: 
##   * rotation around X by angle PSI    ("roll")
##   * rotation around Y by angle THETA  ("pitch")
##   * rotation around Z by angle PHI    ("yaw")
##
##   In this library, euler angles are given in degrees. The functions that
##   use euler angles use the keyword 'Euler' in their name.
