Camera lookAt not working with stereoeffect

问题

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);
  }

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

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

回答1:

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();
