Added a script for creating maps to help visualize the relationship between the various scaling factors.
I refactored some things. Smaller independent functions are good.
Tweaked a little more.
More refactoring. No longer a monolith, but a toolset for manipulating heightmaps. Not too shabby.
Renaming the directory to something more meaningful.
Renaming stuff.
Moved map_scaling out of tests because imports are hard.
Updated map_scaling to be more friendly to interactive sessions.
Refactored generate_map. Instead of a monolith, it's a series of components, making it friendlier for interactive use.
Reasonable test dataset. Large enough for reasonable subslicing experimentation.
Added a docstring, and now topo() supports a viewport argument for select subsections of the map.
Whoops. The scaling factor has to be introduced DURING the simplex() call.
Whoops. Typo'd the placement of that one.
This is now a working demo
