THREE.js несколько рендеров все динамически изменяет размер

0 голосов
/ 30 августа 2018

Мой первый холст отображает мой первый рендерер, который соответствующим образом изменяется в окне браузера. Однако мой второй рендер на втором холсте не изменяет размер, несмотря на использование того же метода.

Конечная цель состоит в том, чтобы в конечном итоге иметь больше функций рендеринга с текстовой информацией, относящейся к рендерерам.

Может быть, я поступаю неправильно, но любой совет будет полезен. Спасибо.

Вместо создания другой функции создайте общую функцию и передайте свой холст для обработки нескольких средств визуализации.

DEMO 

function rendererCommon(canvas) {
    var renderer = new THREE.WebGLRenderer({
            canvas: document.getElementById(canvas),
            antialias: true
        }),
        camera = new THREE.PerspectiveCamera(35, window.innerWidth / window.innerHeight, 0.1, 3000),
        scene = new THREE.Scene(),
        light = new THREE.AmbientLight(0xffffff, 0.5), // will light the dark sides of the object;
        light1 = new THREE.PointLight(0xffffff, 0.5), //will light the front of the object
        geometry = new THREE.CubeGeometry(100, 100, 100), //(x,y,z) ?,
        material = new THREE.MeshLambertMaterial({
            color: 0xF3FFE2
        });// this material will alow color, the parameter sets the solor of the object

    renderer.setClearColor(0x00ff00);
    renderer.setPixelRatio(window.devicePixelRatio);
    renderer.setSize(window.innerWidth * .4, window.innerHeight * .4);


    //WINDOW RESIZE FUNCTION 

    window.addEventListener("resize", onWindowResize);

    function onWindowResize() {

        camera.aspect = (window.innerWidth * .4) / (window.innerHeight * .4);

        camera.updateProjectionMatrix();
        renderer.setSize(window.innerWidth * .4, window.innerHeight * .4);
    }



    scene.add(light);
    scene.add(light1);

    let mesh = new THREE.Mesh(geometry, material);
  
    mesh.position.set(0, 0, -1000);

    scene.add(mesh);

    //ANIMATION 
    requestAnimationFrame(render);

    function render() {
        mesh.rotation.x += 0.1;
        mesh.rotation.y += 0.1;
        renderer.render(scene, camera);
