Currently, I am in the process of developing a website utilizing three.js technology. For a preview, you can check out the demo by visiting: . The website is designed on canvas to ensure compatibility with iOS and Android devices.
My main query pertains to how I can smoothly transition the camera from its initial position to the location of an object that has been clicked. Is there a more efficient method than using the translate function separately on each axis?
Appreciate your insights!

const handleMouseClick = (event) => {
event.preventDefault();
const vector = new THREE.Vector3(
renderer.devicePixelRatio * (event.pageX - this.offsetLeft) / this.width * 2 - 1,
-renderer.devicePixelRatio * (event.pageY - this.offsetTop) / this.height * 2 + 1,
0.5
);
projector.unprojectVector(vector, camera);
const raycaster = new THREE.Raycaster(
camera.position,
vector.sub(camera.position).normalize()
);
const intersects = raycaster.intersectObjects(YOUR_CLICKABLE_OBJECTS);
if (intersects.length > 0) {
camera.position.copy(intersects[0].point);
// Alternatively: camera.position.copy(intersects[0].object.position.clone());
}
};
renderer.domElement.addEventListener('mousedown', handleMouseClick, false);
This script:
If you prefer a gradual transition of the camera to the clicked location instead of an abrupt jump, consider utilizing a tweening library such as TweenJS for precise control over the animation timing.
(P.S.: The use of renderer.devicePixelRatio might only be necessary for WebGL renderers; feel free to omit it for other renderers.)
