HitResultNode

open class HitResultNode(engine: Engine, val hitTest: HitResultNode.(Frame) -> HitResult?) : TrackableNode<Trackable>

AR real time AR HitTest positioned node.

This PoseNode follows the actual ARCore detected orientation and position at the provided relative X, Y location in the ARSceneView

Performs a ray cast from the user's device in the direction of the given location in the camera view. Intersections with detected scene geometry are returned, sorted by distance from the device; the nearest intersection is returned first.

Constructors
