Multiple views of single cesium.viewer

I want to have 2 (multiple) camera views of cesium.viewer. One view that is standard cesiumContainer, and the other one, like a thumbnail, showing a different camera angle. How this can be achieved? Is there any example present.
Thanks

Hello,

There is currently no support for multiple cameras in one scene. Instead, you would have to create a second cesium.viewer to display in the thumbnail.

OK. So that means for 2nd viewer all code will be duplicated to run similar
application, or is there some way around!

Yeah, unfortunately I think that’s the only way to do this right now without making changes to the scene.

See this thread for some additional information: https://groups.google.com/d/msg/cesium-dev/rsoFNBslEDE/JBKASJRSO-UJ

A large part of this is due to current limitations of WebGL.

Hi everyone, is there any update about this problem? Since 9 years passed I hope that we have one. @Matt_Amato @hannah
