DESCRIPTION

68       This  engine takes two inputs, representing a vector before and after a
69       rotation has been applied. As output, it produces  the  rotation  value
70       that would cause the first vector to transform into the other.
71
72       The  input fields can have multiple values, allowing the engine to com‐
73       pose several rotations in parallel. Some inputs may  have  more  values
74       than  others.  In such cases, the last value of the shorter inputs will
75       be repeated as necessary.
76

INPUTS

78     SoMFVec3f           from
79          Vector before the rotation.
80
81     SoMFVec3f           to
82          Vector after the rotation.
83
84

OUTPUTS

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