Question

有一共1000+个点，如果setView将orientation的pitch设置为-90度是可以俯瞰每个点的。

但是，一旦想用其他视角观察，改变角度就会无法看到坐标上的点。

有什么好的办法来批量设置这些点的position和orientation

Answer 1

您好，您这边这个点数据是什么样的数据呢？

我这边测试点数据在pitch设置不同的俯仰度都可以看到的。

能否提供一下这些点数据呢，我这边做一个测试。

选了一些数据发过去了，我看下您这边，setView或者flyTo的代码里position和orientation是怎么写得

感谢。

---

嗨，您好，什么时候方便了，能提供一下解决方案吗，感谢

---

  viewer.scene.camera.setView({
        destination : new Cesium.Cartesian3(x,y,z),
        orientation : {
            heading : heading,
            pitch : pitch,
            roll : roll
        }
    });

然后 flyTo的offset是可以设置偏移的，您可以将offset设置为当前相机视角的headingpitchroll。

---

我可能没说清：给定一系列的点坐标，如果setView中pitch是-90度，就是俯视没问题；想要修改这个角度斜着看，则画面中就看不到这个点了，此时应该如何对应修改setView中的数值。

---

您所说的看不见是指不在视野范围内？

如果是这样的话,和您的方位角应该也是有关系的，您可以通过变换方位角来使数据出现在可视方向。

另外，相机定位您默认的是飞到所选中的点的X,Y坐标。您也可以通过对相机定位点的X,Y坐标进行一定的计算，使相机能够看见所选的目标点

---

还有就是超图Cesium的API里没有offset

---

你好啊，我就是因为数据量太大了，要是只有几十个数据，我就穷举了。

我现在就是想通过给定的经纬度坐标来批量的做。

这个对X,Y的计算我应该怎么做啊

---

方便打电话，语音或者其他方式吗，你们着bbs太难用了

---

您私信我您的电话或者QQ，微信，联系方式均可。

---

该问题楼主想要实现的功能是，定位到目标点的同时可以看到目标点。这个功能除非是楼主所说的90度俯视，否则看不见的。

如果非要实现类似功能

1.如果角度可以固定的话，设置一个固定角度，修改定位点的X,Y坐标即可

2.如果角度不想固定的话，根据当前角度获取屏幕中心点，然后计算经纬度差值，直接计算反方向的中心点坐标。以该坐标作为相机坐标。
