ThreeJS how to create a Plane, and a sphere, box sit on top of it

Basically need to Create BoxGeometry, ShereGeometry and a PlaneGeometry 

Below is the basic code for it. 

<script type="module">

import * as THREE from './threejs/build/three.module.js';

import { GUI } from './threejs/examples/jsm/libs/dat.gui.module.js';

import { OrbitControls } from './threejs/examples/jsm/controls/OrbitControls.js';

var renderer, scene, camera;

var spotLight, lightHelper, shadowCameraHelper;

var gui;

renderer = new THREE.WebGLRenderer();

renderer.setPixelRatio(window.devicePixelRatio);

renderer.setSize(window.innerWidth, window.innerHeight);

document.body.appendChild(renderer.domElement);

camera = new THREE.PerspectiveCamera(35, window.innerWidth / window.innerHeight, 300, 10000);

scene = new THREE.Scene();

//LIGHTS 

var light = new THREE.AmbientLight(0xfffff, 0.5);

scene.add(light);

var light2 = new THREE.PointLight(0xffffff, 0.5);

scene.add(light2);

var material = new THREE.MeshBasicMaterial({

color: 0xff0000,

transparent: true,

opacity: 1,

wireframe: true

});

var geometry = new THREE.BoxGeometry(100, 100, 100);

var mesh = new THREE.Mesh(geometry, material);

mesh.position.z = -1000;

mesh.position.x = -100;

scene.add(mesh);

var geometry2 = new THREE.SphereGeometry(50, 20, 20);

var mesh2 = new THREE.Mesh(geometry2, material);

mesh2.position.z = -1000;

mesh2.position.x = -100;

scene.add(mesh2);

var geometry3 = new THREE.PlaneGeometry(10000, 1000, 100, 100);

var mesh3 = new THREE.Mesh(geometry3, material);

mesh3.rotation.x = -90 * Math.PI / 180;

mesh3.position.y = -100;

scene.add(mesh3);

render();

function render() {

mesh.rotation.x += 0.01;

mesh.rotation.y += 0.01;

renderer.render(scene, camera);

requestAnimationFrame(render);

}

</script>
