@chemistry/math

Linear algebra library for 3D chemistry — vectors, matrices, quaternions, and transforms.

Installation

npm install @chemistry/math

Usage

import { Vec3, Matrix3x3, Quaternion, Transform3D } from '@chemistry/math';

const v = new Vec3(1, 2, 3);
const normalized = v.normalize();

const m = Matrix3x3.identity();
const transformed = m.multiplyVec3(v);

const q = new Quaternion(0, 0, 0, 1);
const rotated = q.rotate(v);

Features

• Vec2 / Vec3 — 2D and 3D vector operations
• Matrix3x3 / Matrix3x4 — matrix operations and transformations
• Quaternion — quaternion math for rotations
• Transform3D — combined translation, rotation, and scale
• Isomorphic — works in Node.js and browsers
