DESCRIPTION

       This engine takes as input a rotation, and decomposes it into an axis value and a rotation
       angle (in radians).

       The  input can have multiple values, allowing the engine to decompose several rotations in
       parallel.

INPUTS

     SoMFRotation        rotation
          Rotation to be decomposed.

OUTPUTS

     (SoMFVec3f)         axis
          Axis of rotation derived from the input.

     (SoMFFloat)         angle
          Angle (in radians) derived from the input.

METHODS

                         SoDecomposeRotation()
          Constructor

FILE FORMAT/DEFAULTS

       DecomposeRotation {
          rotation  0 0 1  0
     }
