javascript - 添加一个 THREE.Points 到场景 : THREE. Object3D.add : object not an instance of THREE. Object3D (Javascript)

Question

我正在尝试添加一个系统粒子，一个三点到场景，但我有这个错误:

“THREE.Object3D.add:对象不是 THREE.Object3D 的实例。未定义”

代码:

var backCount = 1800;
var particlesG = new THREE.Geometry();

for (var p = 0; p < backCount; p++) {
    var backgroundP = new THREE.Vector3();
    backgroundP.x = Math.random() * 3000 - 1500;
    backgroundP.y = Math.random() * 3000 - 1500;
    backgroundP.z = Math.random() * 3000 - 1500;
    particlesG.vertices.push(backgroundP);
}

var pMaterial = new THREE.PointsMaterial({color: 0xFFFFFF});

var particleSystemS = THREE.Points(particlesG, pMaterial);


scene.add(particleSystemS);

谢谢

在THREE.Points之前添加新内容。

var molecularSystemS = new THREE.Points(articlesG, pMaterial);
