Create Anchor in AR at center of screen and move it near or far with respect to camera same like magicplan

Question

I want to create an app same like magicplan and want to draw continuous green vertical pipe same like magicplan which goes near and far as camera moves.

I have tried below code but it keeps node at center of screen. Please help me how I can achieve this.

                Ray ray = arFragment.getArSceneView().getScene().getCamera().screenPointToRay(arFragment.getArSceneView().getWidth() / 2, arFragment.getArSceneView().getHeight() / 2);
                Vector3 localpos = ray.getPoint(1f);
                Quaternion localRotation = arFragment.getArSceneView().getScene().getCamera().getLocalRotation();
                Vector3 localScale = new Vector3(0.3f,0.3f,0.3f);
                Frame frame = arFragment.getArSceneView().getArFrame();
                Vector3 pos;
                pos = Vector3.add(ray.getOrigin(), ray.getDirection());

                Pose pose = Pose.makeTranslation(pos.x, pos.y, pos.z);

                anchor = arFragment.getArSceneView().getSession().createAnchor(pose);
                anchorNode = new AnchorNode(anchor);
                anchorNode.setParent(arFragment.getArSceneView().getScene());
                TransformationSystem transformationSystem = arFragment.getTransformationSystem();
                node = new TransformableNode(transformationSystem);
                node.setRenderable(cylinderRenderable2);
                node.setParent(anchorNode);
                node.setLocalPosition(localpos);
                node.setLocalRotation(localRotation);
                node.setLocalScale(localScale);
                node.select();
