我正在尝试从交叉平面创建一棵“树”，每个平面都有来自 png 的透明纹理。而且看起来网格的一部分总是缺乏透明度。

这是一个例子： https: //jsfiddle.net/tncku896/5/

let camera, scene, renderer;
let group;

init();
animate();

function init() {
    camera = new THREE.PerspectiveCamera(70, window.innerWidth / window.innerHeight, 0.1, 100);
    camera.position.z = 1.5;
    scene = new THREE.Scene();
    scene.background = new THREE.Color(0xbbbbbb);
    renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(renderer.domElement);
    
    let loader = new THREE.TextureLoader();
    let texture = loader.load('https://i.imgur.com/QxFQi1G.png');
    texture.magFilter = THREE.NearestFilter;
    texture.minFilter = THREE.NearestFilter;
    let geometry = new THREE.PlaneBufferGeometry(83/100, 139/100);
    let material = new THREE.MeshBasicMaterial({
        map: texture,
        side: THREE.DoubleSide,
        transparent: true
    });
    
    group = new …
