NAME
       SoComposeRotationFromTo	--  composes  a	rotation that rotates from one
       vector into another

DESCRIPTION
       This  engine takes two inputs, representing a vector before and after a
       rotation	has been applied. As output, it	produces  the  rotation	 value
       that would cause	the first vector to transform into the other.

       The  input fields can have multiple values, allowing the	engine to com-
       pose several rotations in parallel. Some	inputs may  have  more	values
       than  others.  In such cases, the last value of the shorter inputs will
       be repeated as necessary.

INPUTS
     SoMFVec3f		 from
	  Vector before	the rotation.

     SoMFVec3f		 to
	  Vector after the rotation.

OUTPUTS
     (SoMFRotation)	 rotation
	  A rotation that transforms one vector	into another.

METHODS
			 SoComposeRotationFromTo()
	  Constructor

FILE FORMAT/DEFAULTS
