@math.gl/core

What is @math.gl/core?

@math.gl/core is a JavaScript library that provides a suite of mathematical utilities for 3D graphics and geospatial applications. It includes functions for vector and matrix operations, quaternion calculations, and other mathematical computations commonly used in computer graphics and geospatial applications.

What are @math.gl/core's main functionalities?

Vector Operations

This feature allows you to perform vector operations such as addition, subtraction, and normalization. The code sample demonstrates how to create vectors and add them together.

const { Vector3 } = require('@math.gl/core');
const v1 = new Vector3(1, 2, 3);
const v2 = new Vector3(4, 5, 6);
const v3 = v1.add(v2);
console.log(v3); // Vector3 { x: 5, y: 7, z: 9 }

Matrix Operations

This feature provides functions for matrix operations such as multiplication, inversion, and transformation. The code sample shows how to create identity and translation matrices and multiply them.

const { Matrix4 } = require('@math.gl/core');
const m1 = new Matrix4().identity();
const m2 = new Matrix4().translate([1, 2, 3]);
const m3 = m1.multiplyRight(m2);
console.log(m3); // Matrix4 { elements: [1, 0, 0, 1, 0, 1, 0, 2, 0, 0, 1, 3, 0, 0, 0, 1] }

Quaternion Calculations

This feature allows you to perform quaternion calculations such as creating quaternions from axis rotations and multiplying quaternions. The code sample demonstrates how to create and multiply quaternions.

const { Quaternion } = require('@math.gl/core');
const q1 = new Quaternion().fromAxisRotation([0, 1, 0], Math.PI / 2);
const q2 = new Quaternion().fromAxisRotation([1, 0, 0], Math.PI / 2);
const q3 = q1.multiply(q2);
console.log(q3); // Quaternion { x: 0.5, y: 0.5, z: 0.5, w: 0.5 }
