无人扫描示例

实现思路
1.绘制圆柱体根据参数调成圆锥形状
2.加载动画czml路径
3.通过时钟对象获取当前路径点
4.将当前路径点通过 CallbackProperty 赋值给圆锥
5.路径点每次改动圆锥随之移动

代码

获取路径点(移动的实体目标)

let cartesian = entity.position.getValue(this.clock.currentTime);
let positions = this.mouseManager.worldToLonlat(cartesian); 
this.scanEntity =    

this.dynamicCylinder({positions:positions,entity:entityObj,v:this.CoreV,cylinder:{legnth:600000,slices:4,bottomRadius:600000/2}});
this.EntityObj.push(this.entitys.add( this.scanEntity));

传递的动态路径点实现绑定效果(CallbackProperty)

function dynamicCylinder(obj) {
    let c = obj.cylinder;
    this.options = {
      cylinder: {
        HeightReference: HeightReference.RELATIVE_TO_GROUND, //表示相对于地形的位置。
        length: c.length,     //长度
        topRadius: 0,    //顶点半径
        bottomRadius: c.bottomRadius,  //底部半径
        material: new Color(0, 1, 1, .4),
        slices: c.slices
      }
    }
    this.posi
