Can transform a Sphere into a Torus?

[cTatu]

Hi, I'm interested in using Pytorch3D to create a topology optimization software.
And right now, as I understand it, the only thing it can do is offset the points from the initial shape so, for example, it can't create a hole on its own.
So I was wondering if there could be a way to enable de optimization algorithm to change the topology of the initial shape.

Thanks
