The reference and control curve define the morph. For each point on the reference curve, there is a corresponding point with the same number on the control curve.
The distance and direction between two corresponding points on the two curves defines the morph. If the points on the selected objects lie on the reference curve, they are moved to the corresponding point on the control curve.
Note:
- The position of corresponding points on the curves is important. In the example above, the keypoints correspond, producing the expected morph. If the keypoints do not correspond, the resulting morph may have an unexpected twist.
- If the points on the selected objects don't lie on the reference curve, the Method option determines how the points will move.
