倒影水

Name Type Description

scene Scene viewer中的scene对象

options

Object

optional 对象具有如下属性:

Name	Type	Description
`positions`	Array	optional 水面的边界坐标(经纬度)集合，单位为度.其与options.polygonHierarchy选项互斥.
`polygonHierarchy`	PolygonHierarchy	optional 其与options.positions选项互斥.边界范围，`PolygonHierarchy`可含洞或者岛
`id`	String	optional 对象的id
`height`	Number	optional 水面的高度，默认值为0
`reflectHeight`	Number	optional 反射面高程，默认值为0.0
`uniformEelevation`	Number	optional 是否将水面置为统一平面，如果是则水面的边界点高程值为height，否则在原有高程基础上增加height高度,默认值为false
`waterColor`	Color	optional 水面颜色，其透明度决定了水面的透明度，默认值为Color(0.0,0.0,0.0,0.8)
`reflectBlendColor`	Color	optional 倒影融合颜色，默认值为Color(1.0, 1.0, 1.0, 1.0)

Examples:

const water = new Cesium.WaterReflecter(viewer.scene, {
 positions:[116.9648,33.658527,116.9678990,33.6585,116.968,33.66125,116.9645,33.6612,],
 height:30.0
});
viewer.scene.addReflectWater(water);

const loadPromise = Cesium.GeoJsonDataSource.load('data/vector/polygon/suzhouwater0807/layer.json');
loadPromise.then(function(dataSource) {
  const entities = dataSource.entities.values;
    for (let i = 0; i < entities.length; i++) {
      let entity = entities[i];
      let options = {
        polygonHierarchy:entity.polygon._hierarchy._value,
        height:30,
      };
      const water = new Cesium.WaterReflecter(viewer.scene,wtateoption);
      viewer.scene.addReflectWater(water);
   }
