veccentric

Tiny 2D vector library. Inspired by p5.js's p5.Vector.

Usage

Add veccentric to your Cargo.toml.

[dependencies]
veccentric = "0.3"

Basic arithmetic on Vecc<T>.

use veccentric::Vecc;

let a = Vecc::new(3_i32, 4);
let b = a * 5;
let c = Vecc::new(-10, -8);
let d = b - c;
let e = -d;

Fecc's extended API.

use veccentric::Fecc;

let a: Fecc = (3.0, 4.0).into();
let b = a / 0.2;
let c = b.limit(20.0);
let d = c.rotate(PI);
let e = d.turn(0.0);

lib.rs:

Tiny 2D vector library. Inspired by p5.js's p5.Vector.

The main type, Vecc<T>, is a generic struct implementing many useful traits and operator overloading. Fecc is a type alias for Vecc<f64>. It has an extended API, heavily inspired by p5.Vector.

Features

The random feature enables additional methods on Fecc: from_rng, from_seed, from_entropy.

The all feature enables just random.

Notes

float_cmp::assert_approx_eq is used in some examples.

Examples

use veccentric::Fecc;

let a = Fecc::new(3.0, 4.0);
assert_approx_eq!(f64, a.mag(), 5.0);

let five_a = a * 5.0;
assert_approx_eq!(f64, five_a.mag(), 25.0);

let b = Fecc::new(-3.0, 0.0);
let c = a + b; // (0.0, 4.0)
assert_approx_eq!(f64, c.angle(), PI / 2.0);
