Morphing is an old technique that moves vertex to match next figure . We could make a function ....something like an add on to morph differents keys of a figure. In the past it was absolutely necesary that both figures had the same quantity of vertex to work ...I've seen somewhere advanced programms that this is not necesary, but in this example I show you the old school technique .
In this example, you can flay with cursor keys to get closer to the object to see how vertes move to match the othe figure .
