Don't you mean that the ellipse radius is 1/2 of the edge length of the
cube?

You probably don't want the center of the image to lie at the origin, but
in the center of your edge if I understand correctly, at least for 2 of
your 3 dimensions, and at the origin for the 3rd dimension to obtain a
half-dome.
