vector_math.js v0.1.0

vector_math.js

A Node.js vector math library for 3D and 2D applications

Javascript version of vector_math.dart with SIMD implementation from glMatrix

Features

• 2D, 3D, and 4D vector and matrix types.
• Quaternion type for animating rotations.
• Collision detection: AABB, rays, spheres, ...
• Fully documented.

Missing features

• Utilities like color and common rendering related operations
• Flexible getters and setters, for example, position.xwz = color.grb;.

Example

This sample code shows how to manipulate matrices :

var m1 = Matrix4.identity();
var m2 = new Matrix4(0.0, 1.0, 2.0, 3.0,
                     0,0, 1.0, 2.0, 3.0
                     0.0, 1.0, 2.0, 3.0);
var scale_mul = m1.scaled(0.5).mult(m2);

This sample code shows how to manipulate vectors :

var v1 = Vector3.zero();
var v2 = new Vector3(1.0, 0.0, 2.0);
console.log("Dot product = ") + v1.dot(v2));
console.log("v1 + v2 = " + v1.added(v2).toString());
