我有以下代码:

...
camera = new THREE.PerspectiveCamera(75, screenRatio, 1, 10000 );
camera.position.z = -10; // position.set(0, 0, -10) also not working.
controls = new THREE.VRControls( camera );
effect = new THREE.VREffect( renderer );
effect.setSize( window.innerWidth, window.innerHeight );
...

VRControls 与加速度计同步工作,但我无法更改相机位置。它似乎卡在原点(0,0,0)。在应用 VRControls 和 VREffect 之前它工作得很好。

最佳答案

Mozilla VR Team demos 的 Sechelt 演示中找到了解决方案。我会在这里放一个代码片段作为其他 VR 初学者的引用。

将摄像机添加到组而不是直接更新摄像机位置是移动摄像机的方式。

var scene, renderer, cameraRatio, camera, controls, effect, dolly;

function init() {
    scene = new THREE.Scene();

    renderer = new THREE.WebGLRenderer({ antialias: true });
    renderer.setSize( window.innerWidth, window.innerHeight );
    document.body.appendChild( renderer.domElement );

    cameraRatio = window.innerWidth / window.innerHeight;
    camera = new THREE.PerspectiveCamera( 75, cameraRatio, 1, 1000 );

    controls = new THREE.VRControls( camera );
    effect = new THREE.VREffect( renderer );
    effect.setSize( window.innerWidth, window.innerHeight );

    // This helps move the camera
    dolly = new THREE.Group();
    dolly.position.set( 0, 0, 0 );
    scene.add( dolly );
    dolly.add( camera );

    ...
    // Of course, there should be lights, objects, etc
}

function animate() {
    dolly.position.x += 0.1;
    controls.update();
    effect.render( scene, camera );
}

init();
animate();

关于javascript - 使用 VRControls 时无法更改相机位置,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/34470248/
