Matrix Operations

Perform operations on 4x4 matrices such as creation, translation, rotation, scaling, and more.

const mat4 = require('gl-matrix').mat4;
let matrix = mat4.create();
mat4.translate(matrix, matrix, [2, 3, 4]);
mat4.rotateX(matrix, matrix, Math.PI / 4);

Vector Operations

Perform operations on 3D vectors such as setting values, normalization, cross product, dot product, and more.

const vec3 = require('gl-matrix').vec3;
let vector = vec3.create();
vec3.set(vector, 1, 2, 3);
vec3.normalize(vector, vector);

Quaternion Operations

Perform operations on quaternions for representing rotations such as creating a quaternion, rotating it, inverting it, and more.

const quat = require('gl-matrix').quat;
let quaternion = quat.create();
quat.rotateX(quaternion, quaternion, Math.PI / 2);
quat.invert(quaternion, quaternion);
