How do I get inside the model?

1.对您遇到的问题的简要解释。

During the development process, sometimes I can get inside the model, but sometimes it can’t. Can this be controlled by code?

2.一个最小的代码示例。如果您发现了错误,这有助于我们重现并修复它。

3.背景。你为什么需要这样做?我们可能知道更好的方法来实现您的目标。

我想通过放大或其他方式进入模型内部,然后让视角保持锁定在内部。不要让镜头出来。

4.您正在使用的Cesium版本,您的操作系统和浏览器。

Cesium 1.48

What kind of model is it? Is it just a glTF you’re loading in, or a 3D Tiles model, or something created dynamically with code? Do you have a Sandcastle example you can share?

I believe the camera checks for collision against the terrain, but not 3D models, so you should always be able to zoom inside of models I think.
