If you mean what I think you mean, you can't. Think about it this way:
If you put your picture under a microscope so they have the appearance
of having a large scaling factor applied, they still intersect. Or if
you move the picture so far away from you that they are appear scaled
very small, they still intersect. Unless I don't understand what you
are asking.
