This folder contains examples for using the library. You can run each of them with cargo run --example <example-name> (for example cargo run --example cli_polygon_test).
The core of this example was developed by @bipentihexium. It is a cli utility to test points on the sphere if they are inside a polygon. The default polygon is a non-convex one that kept causing issues in development :D It accepts several command line arguments, in order:
<height>- how many rows to print the result into (kind of resolution). If it can not be parsed to ani32, defaults to50.<width>- how many columns to print the result into (kind of resolution). If it can not be parsed to ani32, defaults toheight*2.<dec-start>- the declination to start at, in radians. If it can not be parsed to anf32, defaults to-PI/2.0.<dec-end>- the declination to end at, in radians. If it can not be parsed to anf32, defaults toPI/2.0.<ra-start>- the right ascension to start at, in radians. If it can not be parsed to anf32, defaults to-PI.<ra-end>- the right ascension to end at, in radians. If it can not be parsed to anf32, defaults toPI.
Points considered to be inside the polygon are yellow, those outside are purple, and colours in between indicate a state in between - it uses MSAA, so each printed point actually checks multiple points in its area and averages the result.
