## What it is
Mathfs is an expanded math library for Unity written in C#, providing functionality beyond Unity's built-in Mathf. It covers 2D intersection tests, curves and splines (Bézier, Hermite, Catmull-Rom, B-Spline, NURBS), trajectory math, and triangle, polygon, and circle geometry.

## Use cases
- compute bezier and spline curves in Unity
- calculate projectile launch angles and trajectories
- test intersections between rays, lines, segments and circles
- compute polygon area and winding number
- get circumcircle and incircle of a triangle
- expand Unity's Mathf with more math helpers

## When to choose
- you're building a Unity game needing advanced 2D geometry or spline math
- you want projectile/trajectory calculations out of the box
- you prefer a lightweight MIT-licensed math library over a full math framework

## When to avoid
- you're not using Unity (the library targets Unity 2021.2+)
- you need 3D intersection tests or a full computational geometry suite
- you need strict API stability, since the author edits APIs freely between versions

## Facets
- artifact type: library
