// 初始化 let viewer = new Cesium.Viewer("viewerContainer") // 分析参数 var viewModel = { verticalAngle: 90, horizontalAngle: 120, distance: 10 }; // 添加可视域 var viewshed = new Cesium.ViewShed3D(viewer, { horizontalAngle: Number(viewModel.horizontalAngle), verticalAngle: Number(viewModel.verticalAngle), distance: Number(viewModel.distance), calback: function () { viewModel.distance = viewshed.distance } });

适合做cesium可视域分析的开发人员，支持普通导入和es6方式引用
