我正在使用OBJLoader.js.我有一个按钮,点击从场景中删除一个3D模型并添加一个新的模型,但每次加载模型时,chrome中的内存使用量增加约50 MB并且不会减少.我尝试过"dispose()"和null,但没有多大用处.每秒都会调用一个使用渲染器渲染场景的动画函数.

function freeMemory(model) {
if (model instanceof THREE.Mesh) {
    var texMat = model.material;
    texMat.map.dispose();
    texMat.map = null;
    texMat.dispose();
    texMat = null;
    model.geometry.dispose();
    model.geometry = null;
    model = null;
 }
}

function loadModel() {
scene.remove(model);
freeMemory(model);
var loader = new THREE.OBJLoader();
loader.load('test3d.obj', function(object) {
    object.children[0].geometry.computeFaceNormals();
    geometry = object.children[0].geometry;
    console.log(geometry);
    geometry.dynamic = true;
    var modelTexture = THREE.ImageUtils.loadTexture("models/tex_0.jpg");
    object.traverse(function(child) {
        if (child instanceof THREE.Mesh) {
            child.material.map = modelTexture;
            model = child;
            model.scale.set(0.5, 0.5, 0.5);
            model.translateOnAxis(new THREE.Vector3(1, 0, 1).normalize(),
                    1.5);
            model.rotation.x = 0; …
