Is there a way to link the OrbitControls of two canvases on the same page? For example, if the user zooms in on one canvas, I want the other canvas to also zoom in simultaneously. How could I achieve this synchronization between multiple canvases?

To synchronize the movement of two different cameras in separate scenes, you can create two instances of orbit controls and update the position and rotation of one camera based on the movements of the other camera.
// set up two scenes with their respective renderers and cameras
const controls1 = new THREE.OrbitControls( camera1, renderer1.domElement );
const controls2 = new THREE.OrbitControls( camera2, renderer2.domElement );
controls1.addEventListener( 'change', () => {
camera2.position.copy( camera1.position );
camera2.rotation.copy( camera1.rotation );
render();
} );
controls1.addEventListener( 'change', () => {
camera1.position.copy( camera2.position );
camera1.rotation.copy( camera2.rotation );
render();
} );
For a practical demonstration, check out this example: https://jsfiddle.net/62x8c139/.
By implementing this approach, both cameras will be synchronized to the exact same position across both scenes.
I hope this solution is helpful for your project!
