Filling in the exposed surface could be done with polygon3d(), with some
work to construct the polygon. Displaying the function across that

3d plot of earth with cut
Hello,
Could someone suggest a package/way to make a 3D raster plot of the Earth
(with continent boundaries), and then make a "cut" or "slice" of it such
that one can also visualize some scalar quantity as a function of the
Radius/Depth across that given slice ?
Formally, I would have a given, fixed longitude, and a list of vectors
{latitude, radius, Value}
that would show
