Simple implementation of the marching squares algorithm in Haskell, with a GUI to manipulate the input data and visualise the output.
To simply build: stack build
To build and run: stack run
Once the program is running, click on any of the grid's nodes (circles) to toggle their state. The default state is off, so clicking once on any of them will toggle them on.
By toggling multiple nodes adjacent to each other, you can visualise how the marching squares algorithm builds a contour around them.
Main.hs: Creates the window.Game.hs: Execution loop and data structures.Rendering.hs: Rendering tasks. This is where the isolines are calculated, and thus the core of the marching squares algorithm in itself.
