How to change Position of ModelRenderable in AugmentedFace Api in AR core Android

[Adityavj2601]

i want to change the postion of obj in real time based on node.getWorldPosition() here is my code i want to change the position of Model Renderable here is my code :

MaterialFactory .makeOpaqueWithColor(this, new Color(android.graphics.Color.BLUE)) .thenAccept(material -> { modelRenderable = ShapeFactory.makeCube(new Vector3(0.01f , 0.01f , 0.01f) ,new Vector3(0f , 0f , 0.1f) , material);

            });

    ArSceneView sceneView = customARFragment.getArSceneView();
    sceneView.setCameraStreamRenderPriority(Renderable.RENDER_PRIORITY_FIRST);

    Scene scene = sceneView.getScene();

    scene.addOnUpdateListener(
            (FrameTime frameTime) -> {
                /*if (modelRenderable == null) {
                    return;
                }

*/

                Collection<AugmentedFace> faceList =
                        sceneView.getSession().getAllTrackables(AugmentedFace.class);

                // Make new AugmentedFaceNodes for any new faces.
                for (AugmentedFace face : faceList) {

                    FloatBuffer buffer = face.getMeshVertices();
                    Vector3 vectorLeftEyeLeft = new Vector3(buffer.get(33 * 3), buffer.get((33 * 3) + 1), buffer.get((33 * 3) + 2));
                    Vector3 vectorLeftEyeRight = new Vector3(buffer.get(133 * 3),buffer.get((133 * 3) + 1), buffer.get((133 * 3) + 2));
                    Node node = new Node();
                    node.setLocalPosition(new Vector3((vectorLeftEyeLeft.x + vectorLeftEyeRight.x) / 2, (vectorLeftEyeLeft.y + vectorLeftEyeRight.y) / 2, (vectorLeftEyeLeft.z + vectorLeftEyeRight.z) / 2));
                    node.setParent(faceNodeMap.get(face));
                    Vector3 vector3 =  node.getWorldPosition();

                    AugmentedFaceNode faceNode = new AugmentedFaceNode(face);
                    faceNode.setParent(scene);
                    faceNode.setFaceRegionsRenderable(modelRenderable);
                    faceNodeMap.put(face, faceNode);

                }

                // Remove any AugmentedFaceNodes associated with an AugmentedFace that stopped tracking.
                Iterator<Map.Entry<AugmentedFace, AugmentedFaceNode>> iter =
                        faceNodeMap.entrySet().iterator();
                while (iter.hasNext()) {
                    Map.Entry<AugmentedFace, AugmentedFaceNode> entry = iter.next();
                    AugmentedFace face = entry.getKey();
                    if (face.getTrackingState() == TrackingState.STOPPED) {
                        AugmentedFaceNode faceNode = entry.getValue();
                        faceNode.setParent(null);
                        iter.remove();
                    }
                }
            });

i want to set modelrenderable on position of vector3 . if you know then let me know and help it's urgent ...
