WGPU Mathematics

A fast and simple math library for game and graphics development.

⚠️ This library is still in active development.

Features

• Vec2, Vec3, Vec4 — generic vector types
• Mat2, Mat3, Mat4 — column-major matrix types
• Quat — quaternion rotations, slerp, and conversion
• Deg, Rad, Tau — angle unit types with automatic conversion
• WGSL-style aliases (vec2, vec3, mat4x4, etc.)

Feature Flags

All dependencies are optional:

Flag	Description
swizzle	Swizzle accessors on vectors (.xyz(), .zyxw(), etc.)
rand	Random generation for vectors and quaternions
serde	Serialize / deserialize all types
bytemuck	Pod and Zeroable impls for all types

Usage

[dependencies]
wgm = "1.0.0"
# or with features:
wgm = { version = "1.0.0", features = ["swizzle", "serde"] }

use wgm::{Vec3, Mat4, Quat};
use wgm::units::Deg;

let a: Vec3<f32> = Vec3::new(1.0, 2.0, 3.0);
let b: Vec3<f32> = Vec3::splat(5.0);
let dot: f32 = a.dot(b);
let cross: Vec3<f32> = a.cross(b);
let norm: Vec3<f32> = a.normalize();

let trs: Mat4<f32> = Mat4::from_translation(Vec3::new(0.0, 1.0, 0.0))
    * Mat4::from_rotation_y(Deg(90.0))
    * Mat4::from_scale(Vec3::splat(2.0));

let q: Quat<f32> = Quat::from_axis_angle(Vec3::unit_y(), Deg(90.0));
let forward: Vec3<f32> = q * Vec3::new(0.0, 0.0, -1.0);
