What is Obstructing object (occluder)?

An obstructing object is something that blocks your view or path, like a wall between you and your favorite toy.

Imagine you're sitting in your room, and there's a big bookshelf right in front of you. You want to see the toy dinosaur on the other side of the bookshelf, but all you can see are books. The bookshelf is acting like an obstructing object, or an occluder, it’s blocking your view.

Think of a curtain in your window. When it's closed, you can’t see outside. That curtain is an obstructing object. But when you pull the curtain open, poof! You can see the park again. Just like that, if someone moves the bookshelf aside, you can finally see that toy dinosaur.

Sometimes, obstructing objects are helpful, they hide things from view or keep you safe. But other times, they’re just in your way, like when you're trying to reach a snack on the top shelf and there's a big chair blocking your path.
