Three.js: How to add envMap correctly?

by

Now I want to have a material like here:
https://threejs.org/examples/#webgl_materials_envmaps_exr

So I would add the following:

* {
margin: 0;
padding: 0;
}

.object {
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
pointer-events: none;
background-color: rgb(200, 200, 200);
}
<script type="module">
import * as THREE from "https://threejs.org/build/three.module.js";

import { OBJLoader } from "https://threejs.org/examples/jsm/loaders/OBJLoader.js";

var container;

var camera, scene, renderer;

var mouseX = 0,
    mouseY = 0;

var windowHalfX = window.innerWidth / 2;
var windowHalfY = window.innerHeight / 2;

var object;

init();
animate();

function init() {
    container = document.createElement("div");
    container.className = "object";
    document.body.appendChild(container);

    camera = new THREE.PerspectiveCamera(
        45,
        window.innerWidth / window.innerHeight,
        1,
        2000
    );
    camera.position.z = 250;

    // scene

    scene = new THREE.Scene();

    var ambientLight = new THREE.AmbientLight(0xcccccc, 0.4);
    scene.add(ambientLight);

    var pointLight = new THREE.PointLight(0xffffff, 2);
    pointLight.position.set(100, 100, 50);

    camera.add(pointLight);
    scene.add(camera);

    // manager

    function loadModel() {
        object.traverse(function (child) {
            //This allow us to check if the children is an instance of the Mesh constructor
            if (child instanceof THREE.Mesh) {
                child.material = new THREE.MeshStandardMaterial({
                    color: "#555",
                    roughness: 0.1,
                    metalness: 0.4
                });
                child.material.flatShading = false;

                //Sometimes there are some vertex normals missing in the .obj files, ThreeJs will compute them
            }
        });
        object.position.y = -90;
        scene.add(object);
    }

    var manager = new THREE.LoadingManager(loadModel);

    manager.onProgress = function (item, loaded, total) {
        console.log(item, loaded, total);
    };

    // model

    function onProgress(xhr) {
        if (xhr.lengthComputable) {
            var percentComplete = (xhr.loaded / xhr.total) * 100;
            console.log("model " + Math.round(percentComplete, 2) + "% downloaded");
        }
    }

    function onError() {}

    var loader = new OBJLoader(manager);

    loader.load(
        "https://threejs.org/examples/models/obj/female02/female02.obj",
        function (obj) {
            object = obj;
        },
        onProgress,
        onError
    );

    //

    renderer = new THREE.WebGLRenderer({ alpha: true });
    renderer.setPixelRatio(window.devicePixelRatio);
    renderer.setSize(window.innerWidth, window.innerHeight);
    container.appendChild(renderer.domElement);

    document.addEventListener("mousemove", onDocumentMouseMove, false);

    //

    window.addEventListener("resize", onWindowResize, false);
}

function onWindowResize() {
    windowHalfX = window.innerWidth / 2;
    windowHalfY = window.innerHeight / 2;

    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();

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

function onDocumentMouseMove(event) {
    mouseX = (event.clientX - windowHalfX) / 2;
    mouseY = (event.clientY - windowHalfY) / 2;
}

//

function animate() {
    requestAnimationFrame(animate);
    render();
}

function render() {
    camera.position.x += (mouseX - camera.position.x) * 0.05;
    camera.position.y += (-mouseY - camera.position.y) * 0.05;

    camera.lookAt(scene.position);

    renderer.render(scene, camera);
}
</script>

Unfortunately, it does not work. Why?

I would be very thankful if somebody could help me! 🙂

  1. I have been exploring for a bit for any high-quality articles or blog
    posts in this sort of house . Exploring in Yahoo I
    eventually stumbled upon this site. Reading this information So i am happy to express that I
    have an incredibly excellent uncanny feeling I came upon just what I needed.
    I so much certainly will make certain to do not put out of your mind this web
    site and give it a look regularly. http://herreramedical.org/azithromycin
