Implementation of the marching squares algorithm to find the boundaries of shapes given a scalar field. This algorithm can also be used to generate heightmaps or to find the medial axis of a shape.
To understand what the library can do take a look at the examples.
$ cargo run --release --example function
$ cargo run --release --example heightmap data/italy.png
$ cargo run --release --example medial_axis data/logo.png 20
