hi,刚看到一篇关于风场的科普文章,明白了U和V的意义,第二个问题已然明了了:)

hi,另外我移植到cesium1.5.3的时候,发现要做个销毁判断
//释放前一次粒子对象绘制的primitive
removeLines: function () {
if (this.lines) {
_primitives.remove(this.lines);
//1.5.3版本
if(!this.lines.isDestroyed())
{
this.lines.destroy();
}
}
},

谢谢对代码bug提醒。
风场的工程是参照其它git工程:https://github.com/kobeCan/cesium-wind
没有深入研究算法。
该工程绘制效率不是很理想,可以通过重写primitive接口实现高效率绘制。
