Displace surface with an object

Hi all,

I am using Rhino 5. I would like to displace surfaces, not with a map but with an object, like in this video at 3:00 :


I have no idea how to do that. Anyone can help ?

Thanks by advance

PS : I can use Grasshopper if necessary

@jeremie.o Don’t re-post the same question in a new post. Push surface with an object
