fmath

Math Library for my personal Rust Projects

About

This is not a general-purpose math library. It is specifically written for my purposes only.

Feel free to use it in your projects if it fits your needs, don't even worry about attribution :)

How to use

Include

in Cargo.toml file... rust [dependencies] fmath = "0.2.4"

Documentation

Example

```rust

use fmath::{ types::{ , color:: }, functions::angles::degreestoradians };

let v1 = Vector2::newleft(); let v2 = Vector2::newright(); let v3 = Vector2::new( 0.25, 0.247 );

let vector2addition = v1 + v3; let mut expectedresult = Vector2::new( -0.75, 0.247 );

println!("v1: {}, v2: {}, v3: {}\nv1 + v3 = {}", v1, v2, v3, vector2addition); assert!( vector2addition == expected_result );

let vector2subtraction = Vector2::new(0.8743, 123.523) - Vector2::new(12.52, 47.373); expectedresult = Vector2::new(-11.6457, 76.15 ); assert!( vector2subtraction == expectedresult );

let vector2multiplication = Vector2::new(235.2, 6531.122) * 3.1; expectedresult = Vector2::new( 729.12, 20246.4782 ); assert!( vector2multiplication == expectedresult );

let translate = Vector3::new( 0.1, 4.2, 22.0 ); let eulerrotation = Vector3::new( degreestoradians( 90.0 ), degreestoradians( 45.0 ), degreestoradians( 15.0 ), ); let scale = Vector3::newone();

let trs = Matrix4x4::newtrs( translate.asarray(), eulerrotation.asarray(), scale.as_array() );

let point = Vector3::new( 1.2, 0.5, -2.0 ); println!( "{}", trs.mul_vector3( &point ) );

// COLORS ======================================================

let mut color = RGB::fromhex( "#44FF00" ).unwrap(); println!("{}", color); // print as 8-bit values color.setaf32( 0.5 ); // set alpha to 1.0 println!("{}", color.formatasfloatrgba()); // print as floats

let hsv = HSV::new( 251.0, 0.52, 0.77 ); println!("{}", hsv); println!("HSV as {}", hsv.as_rgb());
