Have anyone made such a plugin or have an idea how to attack the problem?

I can see there is plenty of solutions when googling.

Maybe you can try using stereographic projection, but it would be better write a plugin.

If you already found the algorithm it would not be so difficult to write a dynamic plugin that implements it.
