The normal of the hit.

## Declaration

```swift

```

## Discussion

Discussion The frame of reference for this point depends on the reference entity used in the call to either the raycast(origin:direction:length:query:mask:relativeTo:) method or the convexCast(convexShape:fromPosition:fromOrientation:toPosition:toOrientation:query:mask:relativeTo:) method that generated the hit.
