Checking for ray intersection with an object in Three.js based on its unique identifier

Can you determine if a ray intersects an object based on the order it was placed in the scene?

Check for intersections using: intersects = point.intersectObjects( scene.children );

Answer №1

the intersects method will always provide objects in order of their proximity.
however, you have the option to assign names to objects when adding them to the scene. By naming objects, you can then easily reorder them based on these names.

for example:
when adding an object to the scene, designate its name as an integer value from a counter variable.

once you receive the intersect array, you can utilize the array.sort() function to arrange them accordingly.

it's important to note that this approach is only effective if the objects are grouped within their own group or Object3D, as individual meshes cannot be assigned names.
