I have two objects with the same number of vertices. I need to array them along the curve but the first object has to morph into the second one evenly during the array. So each next copy will be slightly deformed to remind the shape of the last object. 
I add an example from Illustrator. But it perfectly explains the point.
Any suggestions?
