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

> It should be a 2D slice/plane embedded into a 3D space. I was able to come up with the plot, attached. My intention was to plot national boundaries on the surface of a sphere. And put the slice inside. However, I haven't (as yet) worked out how to get the coordinates for the boundaries. Let me know, if of any value. And I'll post the code. (But needs to be polished first)

Thanks for your idea. It should be a 2D slice/plane embedded into a 3D space. Could be static, I just need to make a single figure from it for illustration of the Earth together with its interior in 3D. So, the interior would be a slice in 2D along a fixed longitude. And along this 2D slice would be a heatmap. Again, embedded in 3D, since it would be shown as a slice of Earth in 3D. Duncan?s
