On mesh direct control


Hello there, I was researching some advanced rigging methods and I really like the on mesh direct control Pixar style controllers, and I saw it done in various videos in both Maya and max. But I had no luck finding anything teaching or even talking about the subject or how to achieve it. So I was wondering if anyone could help me out in this even if not by telling me how or just helping me research it.
Thank you very much in advance.

I’m rather sceptical about how much performance this will eat, but you can give it a shot i guess.
