Matrix4

Pakej: @aspose/3d (v24.12.0)

Matrix4 menyimpan matriks transformasi 4×4 sebagai susunan rata 16 nombor dalam row-major order. Ia adalah jenis Transform.transformMatrix dan GlobalTransform.transformMatrix. Elemen individu boleh diakses sebagai m00m33 sifat, atau melalui indeks via getItem(i) / setItem(i, v). Matrix4 dieksport dari @aspose/3d/utilities sub-path.

export class Matrix4
import { Matrix4 } from '@aspose/3d/utilities';

Bina matriks TRS gabungan dan uraikan semula kepada komponen‑komponennya.

import { Matrix4, Vector3, Quaternion } from '@aspose/3d/utilities';

const t = Matrix4.translate(new Vector3(5, 0, 0));
const r = Matrix4.rotate(Quaternion.fromEulerAngle(0, Math.PI / 4, 0));
const s = Matrix4.scale(new Vector3(2, 2, 2));

const trs = t.concatenate(r).concatenate(s);

const translation: any[] = [null];
const scaling: any[] = [null];
const rotation: any[] = [null];
trs.decompose(translation, scaling, rotation);

console.log(`Translation X: ${translation[0].x}`); // Translation X: 5
console.log(`Scale X: ${scaling[0].x.toFixed(4)}`); // Scale X: 2.0000

Kaedah Statik

Matrix4.translate(v)

Mencipta matriks terjemahan tulen daripada a Vector3, atau daripada individu (tx, ty, tz) nombor.

static translate(v: Vector3): Matrix4
static translate(tx: number, ty?: number, tz?: number): Matrix4

ImageRenderOptions

import { Matrix4, Vector3 } from '@aspose/3d/utilities';

const m = Matrix4.translate(new Vector3(3, 0, 0));
console.log(`m03: ${m.m03}`); // m03: 3

Matrix4.scale(v)

Mencipta matriks skala tulen daripada Vector3, atau daripada individu (sx, sy, sz) nombor.

static scale(v: Vector3): Matrix4
static scale(sx: number, sy?: number, sz?: number): Matrix4

Matrix4.rotate(q)

Mencipta matriks putaran daripada Quaternion, atau daripada sudut (dalam radian) dan paksi Vector3.

static rotate(q: Quaternion): Matrix4
static rotate(angle: number, axis: Vector3): Matrix4

ImageRenderOptions

import { Matrix4, Quaternion } from '@aspose/3d/utilities';

const q = Quaternion.fromEulerAngle(0, Math.PI / 2, 0);
const m = Matrix4.rotate(q);
console.log(`Rotation matrix m00: ${m.m00.toFixed(4)}`);
// Rotation matrix m00: 0.0000

Matrix4.rotateFromEuler(rx, ry, rz)

Mencipta matriks putaran daripada sudut Euler dalam radian.

static rotateFromEuler(rx: number, ry?: number, rz?: number): Matrix4
static rotateFromEuler(v: Vector3): Matrix4

Kaedah Contoh

concatenate(m2)

Mengembalikan hasil darab matriks this × m2. Gunakan ini untuk menggabungkan transformasi (laksanakan this pertama, kemudian m2).

concatenate(m2: Matrix4): Matrix4

ImageRenderOptions

import { Matrix4, Vector3 } from '@aspose/3d/utilities';

const translate = Matrix4.translate(new Vector3(1, 0, 0));
const scale = Matrix4.scale(new Vector3(2, 2, 2));
const combined = translate.concatenate(scale);
console.log(`m03: ${combined.m03}`); // m03: 1

inverse()

Mengembalikan invers matriks ini. Melempar pengecualian jika matriks singular (determinan hampir sifar).

inverse(): Matrix4

transpose()

Mengembalikan transpose matriks ini (baris menjadi lajur).

transpose(): Matrix4

normalize()

Mengembalikan matriks baru dengan sub-matriks putaran (3×3 kiri-atas) diortonomalkan dengan membahagi setiap baris mengikut panjangnya. Lajur terjemahan dipelihara.

normalize(): Matrix4

decompose(translation, scaling, rotation)

Mendecomposisi matriks ini menjadi komponen terjemahan, skala, dan putaran. Hasil ditulis ke dalam elemen pertama setiap array output.

decompose(translation: any[], scaling: any[], rotation: any[]): void

ImageRenderOptions

translation any[] — Tatasusunan output. Selepas panggilan, translation[0] adalah objek {x, y, z} dengan terjemahan.

scaling any[] — Tatasusunan output. Selepas panggilan, scaling[0] adalah objek {x, y, z} dengan faktor skala.

rotation any[] — Tatasusunan output. Selepas panggilan, rotation[0] adalah objek {w, x, y, z} dengan komponen quaternion putaran.

ImageRenderOptions

import { Matrix4, Vector3, Quaternion } from '@aspose/3d/utilities';

const m = Matrix4.translate(new Vector3(0, 5, 0));
const trans: any[] = [null], scale: any[] = [null], rot: any[] = [null];
m.decompose(trans, scale, rot);
console.log(`Y: ${trans[0].y}`); // Y: 5

setTRS(translation, rotation, scale)

Menetapkan matriks ini kepada hasil darab terjemahan, putaran, dan skala. Input boleh menjadi objek biasa dengan x, y, z (dan w untuk putaran) medan.

setTRS(translation: any, rotation: any, scale: any): void

toArray()

Mengembalikan salinan array dalaman 16-elemen berformat baris-major.

toArray(): number[]

getItem(index) / setItem(index, value)

Akses elemen mengikut indeks linear (0–15, susunan baris utama).

getItem(key: number): number
setItem(key: number, value: number): void

equals(other)

ImageRenderOptions true jika semua 16 elemen adalah sama secara ketat.

equals(other: Matrix4): boolean
