相机外观无法使用立体效果

问题描述

当我使用以下代码使用立体效果时，我应该如何让我的相机观察某个 Vector3?

When I use stereoeffect using the following code, how should I get my camera to lookAt a certain Vector3?

function animate() {
    var elapsedSeconds = clock.getElapsedTime();
    requestAnimationFrame(animate);

    update(clock.getDelta());
    render(clock.getDelta());
  }

  function update(dt) {
    resize();
    camera.updateProjectionMatrix();
    controls.update(dt);
  }

  function render(dt) {
    effect.render(scene, camera);
  }

我在初始化代码中添加了 camera.lookAt，但我知道 render(..) 函数会不断调用并覆盖我的 lookAt.

I added camera.lookAt in my initialization code but I understand the render(..) function is constantly called and overrides my lookAt.

那么，如何正确初始化场景以便设置我的lookAt点?

So, how do I correctly initialize the scene so that my lookAt point is set?

推荐答案

我认为控件更新更有可能将相机发送回它自己的目标.尝试改为设置控件目标.

I think its more likely the controls update sending the camera back to it's own target. Try setting the controls target instead.

    var lookat = vertex; /// whatever Vector3 you are using already

    controls.target = lookat;
    controls.update();
