Question

var handler = new Cesium.ScreenSpaceEventHandler(scene.canvas);

    //设置鼠标左键单击回调事件
    handler.setInputAction(function(e) {
        //首先移除之前添加的点
        viewer.entities.removeAll();
        //获取点击位置笛卡尔坐标
        var position = scene.pickPosition(e.position);

        //将笛卡尔坐标转化为经纬度坐标
        var cartographic = Cesium.Cartographic.fromCartesian(position);
        var longitude = Cesium.Math.toDegrees(cartographic.longitude);
        var latitude = Cesium.Math.toDegrees(cartographic.latitude);
        var height = cartographic.height;
        if(height < 0) {
            height = 0;
        }

        //创建弹出框信息
        var entity = new Cesium.Entity({
            name : "位置信息",
            description : createDescription(Cesium, [longitude, latitude, height])
        });
        viewer.selectedEntity = entity;

        //在点击位置添加对应点
        viewer.entities.add(new Cesium.Entity({
            point : new Cesium.PointGraphics({
                color : new Cesium.Color(1, 1, 0),
                pixelSize : 10,
                outlineColor : new Cesium.Color(0, 1, 1)
            }),
            position : Cesium.Cartesian3.fromDegrees(longitude, latitude , height + 0.5)
        }));
    }, Cesium.ScreenSpaceEventType.LEFT_CLICK);
 

一直在拾取坐标，怎么结束鼠标事件？

Answer 1

您好，销毁事件就行了handler.destroy()

我来晚了，这种简单的问题我来就行。

买一送一：可视域分析里的viewshed3D = new Cesium.ViewShed3D(scene);如何消除显示？
