three.js - 在 Three.js 中访问 VR 耳机方向

Question

如何在 Three.js 中访问 VR 耳机方向？WebXRManager 似乎没有提供这样做的方法。

Answer 1

您可以从用于渲染场景的相机中提取方向。演示时尝试以下操作：

const position = new THREE.Vector3();
const rotation = new THREE.Quaternion();
const scale = new THREE.Vector3();

// the following line extracts the position, rotation and scale in world space

camera.matrixWorld.decompose( position, rotation, scale );
