deforming a sphere ways?

Hi there,
just wanted to ask if there wasn’t a nice library to deform gridshape based 3D entities like a sphere.

I’d like to have a sphere, for instance, and to make some points moving (± smoothly)
I was okay to do that with nurbs in Max6/Jitter, but I’d need this concept in OF.

Would anyone help me to start ?

There’s an example which could do what you want I think. i don’t know how it’s called off the top of my head, it has a grid sphere, and a cube and a tet I think.
