Vector2, Vector4 — Aspose.3D TypeScript API Reference

import { Vector2, Vector4 } from '@aspose/3d';

export class Vector2

new Vector2(x: number = 0.0, y: number = 0.0)

set(newX: number, newY: number): void

equals(other: Vector2): boolean

static parse(input: string): Vector2

const uv2 = Vector2.parse('0.0 1.0');
console.log(uv2.equals(new Vector2(0.0, 1.0)));  // true

uv.set(1.0, 0.0);
console.log(uv.toString());    // Vector2(1, 0)
