Guide on adjusting the spotlight(s) based on the camera's location in Three.js?

I'm looking to create a dynamic spotlight that moves along with the camera. The code I have currently only maintains the spotlight at the exact position of the camera:

var pointLight = new THREE.PointLight( 0xffffff, 1, 200 );
pointLight.position = camera.position;
scene.add(pointLight);

Is there a way to update this code so that the spotlight is constantly positioned in front of the camera by a set distance? Or essentially, always maintaining a specific relationship to the camera's position?

Answer №1

To enhance the camera's view, incorporate a light source. This way, the light's position will be based on the camera's perspective. Adjust its position by moving it parallel to the z-axis.

camera.add( newLight );
newLight.position = new THREE.Vector3(0,0,10);

One option is to set it up this way:

point.position = camera.position

before each rendering process.

If OrbitControl is being utilized, the setup will appear as follows:

orbit.addEventListener('change', function () {
  render();
});

function render () {
  lights.point.position = camera.position;
  renderer.render(scene, camera);
}

I trust this information proves to be beneficial!
