cesium 1.73 bug ?

似乎发现了一个 cesium 1.73 的bug,

官方样例中的《Plane.html》 对比其他例子,如《Polygon》,《Polyline Volume》等,有个特殊之处,就是当选中一个平面后,
右上角回弹出信息展示框,点击摄像头图标,相机视角会锁定到选中平面,这时按住鼠标左键,拖动鼠标,视角会以选中平面为中心进行旋转,这种相机交互比较舒服;其他例子中就不是这样的,选中物体后,按住鼠标左键进行拖到,视角仍然以地球中心来旋转。

《Polyline Volume》中的var redTube = viewer.entities.add({ … 放到《Plane.html》中,可以看到点击小摄像机图标后的行为是跟选中对象的类型绑定的,分别选中平面 和 3d管道,出现了小摄像机图标,点击它,会发现不同的逻辑。

另一个尝试,可能是cesium自带的bug,把《Plane.html》中的任意一个平面,添加到《Polyline Volume》中,

var redPlane = viewer.entities.add({
     
          name: "Red plane with black outline",
          position: Cesium.Cartesian3.fromDegrees(-107.0, 40.0, 300000.0),
          plane: {
     
            plane: new Cesium.Plane(Cesium.Cartesian3.UNIT_Y, 0.0),
            dimensions: new Cesium.Cartesian2(400000.0, 300000.0),
            material: Cesium.Color.RED.withAlpha(0.5),
            outline: true,
            outlineColor: Cesium.Color.BLACK,
          },
        });

把上面代码插入到 Polyling Volume.html 的39行,

var viewer = new Cesium.Viewer("cesiumContainer");

下面,然后在webstorm打开Polyling Volume.html , 运行后报错:

An error occurred while rendering.  Rendering has stopped.
DataCloneError: Failed to execute 'postMessage' on 'Worker': ArrayBuffer at index 0 is already detached.

有两种解决方法,一个是把插入代码,插入到

var greenBox = viewer.entities.add({
     ...});

的后面;

另一种是注释掉插入代码中的

outline: true,
outlineColor: Cesium.Color.BLACK,
