var handler3D = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas);
handler3D.setInputAction(function (movement) {
var pick = scene.pick(movement.position);
if (pick && pick.id) {
}
}, Cesium.ScreenSpaceEventType.LEFT_CLICK);
pick怎样获取entity的数据的?好像只可以获取entity的id和name,其他数据没办法传到pick的
另外feature跟pick、entity之间的数据是怎样交互转换的?
