我正在尝试使用以下代码创建一个three.js ParticleSystem。在我安装在 Linux 主机上的 Chrome 上，这工作得非常好，但是当我尝试在 Windows Chrome 便携式设备上运行它时，我在第一次渲染调用时收到以下 WegGL 错误：
WebGL：INVALID_OPERATION：vertexAttribPointer：没有绑定ARRAY_BUFFER WebGL：INVALID_OPERATION：drawArrays：属性设置不正确
...来自着色器配置的片段：...

var material = new THREE.ShaderMaterial ( {

particleSystem = new THREE.ParticleSystem(
particles,
material

scene.add(particleSystem);
}
我不知道为什么 VBO 未绑定或无法绑定。到目前为止我发现的与该主题相关的问题：
但两者似乎都不适用于我的情况。
任何帮助将不胜感激；）
