Search a way to make a procedural Surface to a Ball

Hello everybody

First of all sorry for my bad english :o

At the moment i’m testing something out with the procedural mesh in Blueprints.
i have generated a mesh that i can insert the x and y and the polysize:

Now I Search a way to make it to a Ball. I have found a picture to shows a cube and its spherical projection:

And here is my little vertices Generator:

Now would I divide it into 6 equal meshes. Does anyone have an idea how to manipulate the position each loop so that can result from a ball?

thanks for help
