A math library for JavaScript and TypeScript — vectors, matrices, quaternions, and utilities for 3D graphics and creative coding.
npm install wtc-math
The core classes are available from the main entry point:
import { Vec2, Vec3, Vec4, Mat2, Mat3, Mat4, Quat } from "wtc-math";
import { clamp, lerp, map, smoothstep, degToRad } from "wtc-math";
Color, Plane, and Ray are optional — import them only when needed:
import { Color } from "wtc-math/color";
import { Plane } from "wtc-math/plane";
import { Ray } from "wtc-math/ray";
| Class | Description |
|---|---|
Vec2 |
2D vector |
Vec3 |
3D vector |
Vec4 |
4D vector |
Mat2 |
2×2 matrix |
Mat3 |
3×3 matrix |
Mat4 |
4×4 matrix |
Quat |
Quaternion (extends Vec4) |
Color |
RGBA colour in 0–1 space — fromHex, fromHSL, lerp, toCSS |
Plane |
Plane in 3D — distanceTo, projectPoint, intersectLine |
Ray |
Ray in 3D — at, intersectSphere, intersectBox, intersectPlane |
clamp(v, min, max)
lerp(a, b, t)
map(v, inMin, inMax, outMin, outMax)
smoothstep(edge0, edge1, x)
smootherstep(edge0, edge1, x)
degToRad(deg)
radToDeg(rad)
pingpong(t, length)
All structural types are exported:
import type { Vec2Like, Vec3Like, Vec4Like, QuatLike, Mat2Like, Mat3Like, Mat4Like } from "wtc-math";
