I want to put 2d arrows on the edge of the screen that point to a node off screen to show which way to turn the camera so it becomes visible,The node is a real world location represented by a map pin.I wrote code to find if the node sits to the left or right of the frustum when not visible.The way i am trying to do it is by getting a camera coordinate for the node, then -X is on left, +X on the right but it doesnt work as expected, any help really appreciated.var deltaTime = TimeInterval() public func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) { deltaTime = time - lastUpdateTime if deltaTime>1{ if let annotation = annotationsByNode.first { let node = annotation.key.childNodes[0] if !renderer.isNode(node, insideFrustumOf: renderer.pointOfView!) { print("Pin is not visible"); }else { print("Pin is visible"); } let pnt = renderer.projectPoint(node.position) print("pos ", pnt.x) let dir = (isVisible) ? "visible" : ( (pin.x<0) ? "left" : "right") } lastUpdateTime = time } }
