Is it possible that making transformium in unity?

i'm not confident that my sentence means right way...

i want to make object like 'transformium"

In Beginning, an object slice small pieces like tiny box. Next, the pieces are assembled new object shape

like this: https://upload3.inven.co.kr/upload/2020/08/20/bbs/i016468840662.gif

I think when i make that effect these techniques seem to be needed - slice obejct by tiny pieces - assemble tiny pieces in new shpae - tiny pieces moving to position not overlaped

I don't know you understand what i mean becuase of my pool English but if anyone have some ideas to make these effect real, please help me!

--Edit I found a good reference but it seems to be 2d sprite https://www.youtube.com/watch?v=UXcP4JwG79w

And why i can't Enter??
