    Doable on many curved surfaces, Elipsoids as well as spheres are very simple. And I assume that by "rectangular corners" you mean right angles, yes?

    It should be rectangular in danish, maybe it's different in other languages.

    Ok, I guess I could have said simple in spaces with positive curvature.
