ThreeJS camera.lookAt() has no effect, is there something I'm doing wrong?

Question

In Three.js, I want a camera to be pointed at a point in 3D space.

For this purpose, I tried using the camera.lookAt function like so:

camer         


        

Answer 1

Here's an alternative solution: create an object (i.e. cube) with 0 dimensions.

var cameraTarget = new THREE.Mesh( new THREE.CubeGeometry(0,0,0));

In the render function set the camera.lookAt to the position of the cameraTarget.

function render() {
    camera.lookAt( cameraTarget.position );
    renderer.render( scene, camera );
}

Then just move cameraTarget around as you wish.
