Contour interpolation tool
Here you can find an implementation of the interpolation technique outlined in the earth rendering section.
Note this tool just like the technique it implements is unfinished and experimental. Expect this to contain errors, inefficient code and other ugliness.
There is an interactive mode offering visual feedback of the interpolation process but it is not intended to be used for larger files and in fact has not been used much except for testing.
