Class AssessmentAreaLayer

Example

const viewer = new Viewer('cesiumContainer');
const assessmentAreaLayer = new AssessmentAreaLayer({
 viewer,
 sectorProps: [{
     id: 'sector1',
     origin: Cartesian3.fromDegrees(116.3, 32.9),
     heading: 30,
     fov: 30,
     radius: 100000,
     image: '/xxx1.png',
   },
   {
     id: 'sector2',
     origin: Cartesian3.fromDegrees(116.3, 32.9),
     heading: 60,
     fov: 30,
     radius: 100000,
     image: '/xxx2.png',
 },]
});

// 由于图片资源需要异步加载，所以如果想知道图层是否加载完成，可以通过isLoaded属性来判断
if (assessmentAreaLayer.isLoaded) {
 // 通过id获取扇形实例
 const sector = assessmentAreaLayer.getSectorById('sector1');
 // 通过id获取扇形实体的Entity
 const entity = assessmentAreaLayer.getEntityById('sector1');
 // 获取所有实体的DataSource
 const dataSource = assessmentAreaLayer.dataSource;
 // 销毁图层实例
 assessmentAreaLayer.destroy();

 // 如果想要更新扇形实体，先获取扇形实例，然后直接更新对应属性即可
 const sector = assessmentAreaLayer.getSectorById('sector1');
 sector.heading = 60;
}
