# trackedRaycast(from:allowing:alignment:updateHandler:) Performs a tracked ray cast, where a ray is cast into the scene from the center of the camera through a point in the view. ``` @MainActor @preconcurrency func trackedRaycast(from point: CGPoint, allowing target: ARRaycastQuery.Target, alignment: ARRaycastQuery.TargetAlignment, updateHandler: @escaping ([ARRaycastResult]) -> Void) -> ARTrackedRaycast? ``` ## Parameters `point` A point in the view’s local coordinate system. `target` The type of target where the ray should terminate. `alignment` The alignment of the target. `updateHandler` A closure the method calls to update the list of results, sorted from nearest to farthest from the camera. The closure is called on the [`session`](/documentation/RealityKit/ARView/session) instance’s delegate queue. ## Return Value A tracked ray-cast instance used to update or stop ray casting. The result is `nil` if the ray cast fails or if the AR [`session`](/documentation/RealityKit/ARView/session) configuration isn’t or one of its subclasses. --- Copyright © 2026 Apple Inc.
