I'm attempting to verify whether an object (this.target) is facing towards a particular position (newPosition). Here's what I currently have:
new THREE.Matrix4().lookAt( newPosition, this.target.position, this.target.up ) == this.target.matrix
However, it seems that this approach isn't working. What is the correct way to determine if an Object3D is looking at a specific position?
The method you are trying to use may not be effective because the matrix of your target object could be in a different position and scale compared to your source object.
Instead, a more reliable approach would be to perform a raycast from your perspective object to determine if it intersects with the target object.
Explore this example for more information.
var raycaster = new THREE.Raycaster();
raycaster.setFromCamera( mouse, camera );
// Check if the ray intersects with any objects in the scene
var hits = raycaster.intersectObject( mesh );
