DESCRIPTION
     A field containing a single SbRotation (an arbitrary rotation).

     SoSFRotations are written to file as four floating point values separated
     by whitespace. The 4 values represent an axis of rotation followed by the
     amount of right-handed rotation about that axis, in radians. For example,
     a 180 degree rotation about the Y axis is:

	  0 1 0	 3.14159265

FUNCTIONS
     void		 SoSRotationGetAxisAngle(const SoSRotation *this,
			      const SbVec3f *axis, float *angle)
	  Gets the value of the field as an axis/angle.

     void		 SoSRotationSetQ_U_A_T(SoSRotation *this, float q0,
			      float q1, float q2, float q3)
			 SoSRotationSetQuat(SoSRotation *this, float q[4])
	  Set the field to the given quaternion.

     void		 SoSRotationSetAxisAngle(SoSRotation *this, const
			      SbVec3f *axis, float angle)
	  Set the field to the rotation given by axis/angle.

     SoType		 SoSRotationGetClassTypeId()
     void		 SoSRotationGetTypeId(const SoSRotation *this)
	  Returns the type for this class or a particular object of this
	  class.

     const SbRotation *	 SoSRotationGet(const SoSRotation *this)
	  Returns this field's value.

     void		 SoSRotationSet(SoSRotation *this, const SbRotation *
			      newValue)
	  Sets this field to newValue.

     int		 SoSRotationIsEq(const SoSRotation *this, const
			      SoSFRotation *f)
     int		 SoSRotationIsNEq(const SoSRotation *this, const
			      SoSFRotation *f)

Page 2

							     SoSFRotation(3IV)

	  Returns TRUE if f is of the same type and has the same value as this
	  field.
