Using panorama view example
i created a panorama viewer, but the problem is, when i want to switch scene to a normal one, which contains a 3d model and i want to have back default OrbitControls for camera, i can’t find a way to do it, so i just stuck with those settings for Panorama View

app.controls.enableZoom = false;

console.log(app.raycaster);

let isUserInteracting = false,
  onPointerDownMouseX = 0,
  onPointerDownMouseY = 0,
  lon = 0,
  onPointerDownLon = 0,
  lat = 0,
  onPointerDownLat = 0,
  phi = 0,
  theta = 0;
  
  
init();
animate();

function init() {

const container = document.getElementById("v3d-container");      

app.renderer.setPixelRatio(window.devicePixelRatio);
app.renderer.setSize(window.innerWidth, window.innerHeight);
container.appendChild(app.renderer.domElement);

container.style.touchAction = "none";
container.addEventListener("pointerdown", onPointerDown);

document.addEventListener("wheel", onDocumentMouseWheel);
}

function onPointerDown(event) {
  if (event.isPrimary === false) return;

  isUserInteracting = true;

  onPointerDownMouseX = event.clientX;
  onPointerDownMouseY = event.clientY;

  onPointerDownLon = lon;
  onPointerDownLat = lat;

  document.addEventListener("pointermove", onPointerMove);
  document.addEventListener("pointerup", onPointerUp);
}

function onPointerMove(event) {
  if (event.isPrimary === false) return;

  lon = (onPointerDownMouseX - event.clientX) * 0.1 + onPointerDownLon;
  lat = (event.clientY - onPointerDownMouseY) * 0.1 + onPointerDownLat;
}

function onPointerUp() {
  if (event.isPrimary === false) return;

  isUserInteracting = false;

  document.removeEventListener("pointermove", onPointerMove);
  document.removeEventListener("pointerup", onPointerUp);
}

function onDocumentMouseWheel(event) {
  const fov = app.camera.fov + event.deltaY * 0.05;

  app.camera.fov = v3d.MathUtils.clamp(fov, 30, 75);

  app.camera.updateProjectionMatrix();
}

function animate() {
  requestAnimationFrame(animate);
  update();
}

function update() {
  if (isUserInteracting === false) {
    lon += 0;
  }

  lat = Math.max(-85, Math.min(85, lat));
  phi = v3d.MathUtils.degToRad(90 - lat);
  theta = v3d.MathUtils.degToRad(lon);

  const x = 500 * Math.sin(phi) * Math.cos(theta);
  const y = 500 * Math.cos(phi);
  const z = 500 * Math.sin(phi) * Math.sin(theta);

  app.camera.lookAt(x, y, z);

  app.renderer.render(app.scene, app.camera);
}

can’t you use two cameras and switch between them? like here https://v3d.net/ctv

That’s how it can be done quickly in Verge3D. Just nearly an empty scene and two cameras.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

But if you insist on using the code above (which is very excessive) then you should save the current controls as a variable to restore it afterwards.

app.controls.enableZoom = false; //disable zooming
const prevControls = app.controls; //save current controls
app.controls = null; //disable current controls
const container = app.container;

let isUserInteracting,
  onPointerDownMouseX = 0, onPointerDownLon = 0,
  onPointerDownMouseY = 0, onPointerDownLat = 0,
  lon = 0, lat = 0, phi = 0, theta = 0;

init();
update();

function init() {
  container.addEventListener("pointerdown", onPointerDown);
  container.addEventListener("wheel", onMouseWheel);
  container.addEventListener("dblclick", function() {
    if (app.controls) {
      app.controls.enableZoom = false; //disable zooming
      app.controls = null;
      update();
    }
    else {
      app.controls = prevControls;
      app.controls.enableZoom = true; //enable zooming
    }
  });
}

function onPointerDown(event) {
  if (app.controls)
    return;
  isUserInteracting = true;
  onPointerDownMouseX = event.clientX;
  onPointerDownMouseY = event.clientY;
  onPointerDownLon = lon;
  onPointerDownLat = lat;
  container.addEventListener("pointermove", onPointerMove);
  container.addEventListener("pointerup", onPointerUp);
  container.addEventListener("pointerleave", onPointerUp);
}

function onPointerMove(event) {
  lon = (onPointerDownMouseX - event.clientX) * 0.1 + onPointerDownLon;
  lat = (event.clientY - onPointerDownMouseY) * 0.1 + onPointerDownLat;
  update();
}

function onPointerUp() {
  isUserInteracting = false;
  container.removeEventListener("pointermove", onPointerMove);
  container.removeEventListener("pointerup", onPointerUp);
  container.removeEventListener("pointerleave", onPointerUp);
}

function onMouseWheel(event) {
  if (app.controls)
    return;
  const fov = app.camera.fov + event.deltaY * 0.05;
  app.camera.fov = v3d.MathUtils.clamp(fov, 30, 75);
  app.camera.updateProjectionMatrix();
}

function update() {
  lat = Math.max(-85, Math.min(85, lat));
  phi = v3d.MathUtils.degToRad(90 - lat);
  theta = v3d.MathUtils.degToRad(lon);
  const x = 500 * Math.sin(phi) * Math.cos(theta);
  const y = 500 * Math.cos(phi);
  const z = 500 * Math.sin(phi) * Math.sin(theta);
  app.camera.lookAt(x, y, z);
}

Your code worked like a charm, big big thanks

Also you can remove isUserInteracting variable. It’s not used and not needed.
