I want to practice programming with (popular) android physics engines (AndEngine and libgdx).

It is not very difficult to create a small world with physics objects but now I want to create a rope and connect it to objects in the world.

There are several ways to do it, for example:

But I want to see a **smooth** rope like in "Cut The Rope" game on Android and IOS.

Are there any ideas how to do this? I can't find answer yet but I think it would be to create a number of smaller objects tied together but I think this would be bad performance-wise?
