I'm applying the media to the difference of two very large spheres.
Currently, the inner sphere (the Earth's radius) is set to "6375000 *
Meters", where Meters is equal to 4. I'm not sure how big to make the
outer sphere.
Could you please rewrite your density function to take this into
account? I've created a few patterns that begin and end at X distances
away from the center. I managed to get them to work if they are linear,
but act strange when the functions are non-linear.
