Lineal

Lineal is a linear algebra toolkit, for easily and efficiently working with vectors and matrices. It noninvasively extends the prototype of certain arrays to give you just that bit more ease of use than its sister package gl-matrix has to offer, while having only a small and acceptable performance overhead.

npm i lineal

Usage

Lineal has a very similar API to gl-matrix, so check out their documentation for more information. In general, lineal provides static methods that return a brand-new vector or matrix and that work on any vector-like structure (i.e. not necessarily a new Vec2()), and a set of member methods that either mutate the given lineal vector or matrix, or return some kind of computed value. This all sounds more complex than it really is, so let's check out some examples.

import Vec2 from "lineal/vec2"
 
const v1 = new Vec2(1, 2)
v1.add([3, 4])
// v1 is now equal to [3, 6]
 
const v2 = Vec2.add([1, 2], [3, 4]) // returns a brand-new Vec2([3,6])
v2.length() // returns 6.7082039325

That's it! Documentation is coming soon; for now you can just read the source code, which is not difficult to read. If you found any bugs, please report them in the issue tracker so they can be fixed. Have fun programming!
