math

Descripción

This library includes types and functions to handle different types of math.

Compatibility

The types in ecs.math represent widely followed paradigms and can be bridged easily to other libraries.

three.js

The types in ecs.math can be converted to and from the corresponding three.js math types THREE.Vector3, THREE.Quaternion, and THREE.Matrix4 by following the examples below.

const {mat4, quat, vec3} = ecs.math

// Vec3 <--> THREE.Vector3
const v3js = new THREE.Vector3()
const v = vec3.zero()

v3js.copy(v) // Establece un THREE.Vector3 a partir de un Vec3.
v.setFrom(v3js) // Establece un Vec3 a partir de un THREE.Vector3.
const v2 = vec3.from(v3js) // Crea un nuevo Vec3 a partir de un THREE.Vector3.

// Quat <--> THREE.Quaternion
const q3js = new THREE.Quaternion()
const q = quat.zero()

q3js.copy(q) // Establece un THREE.Quaternion a partir de un Quat.
q.setFrom(q3js) // Establece un Quat a partir de un THREE.Quaternion.
const q2 = quat.from(q3js) // Crea un nuevo Quat a partir de un THREE.Quaternion.

// Mat4 <--> THREE.Matrix4
const m3js = new THREE.Matrix4()
const m = mat4.i()

m3js.fromArray(m.data()) // Establece una THREE.Matrix4 a partir de una Mat4.
m.set(m3js.elements) // Establece una Mat4 a partir de una THREE.Matrix4.
const m2 = mat4.of(m3js.elements) // Crea una nueva Mat4 a partir de una THREE.Matrix4
