var redBox = viewer.entities.add({
      name : 'Red box with black outline',
      position: Cesium.Cartesian3.fromDegrees(114.33, 30.35, 300000.0),
      box : {
        dimensions : new Cesium.Cartesian3(200000.0, 300000.0, 200000.0),
        material : Cesium.Color.GREEN.withAlpha(0.5),
        outline : true,
        outlineColor : Cesium.Color.BLACK
      }
    });

在地球上画一个3D立方体；20000.0、300000.0、200000.0，这是大小；

定位到武汉的经纬度绘制；114.33,30.35；

材质，绿色，0.5应该是透明度；outlineColor，边线颜色；

效果如下；在地球上绘3D立方体的基本用途来说，如果你有一个大体的体积需要比拟，可能可用；

前文已提到视角切换控件，来切换了看一下；上面是3D视角；下面是哥伦布视角；

2D视角；

输入武汉的经纬度，搜索；直接定位过去，整个地区都在盒子之内；
