Rotation of the camera on a circular arc with a central point

Hello,

I’m quite a beginner with cesium. I would like to be able to move my camera on an arc of circle with as center the place where my camera points. A bit like the animation of google earth and maps when you go from 2D to 3D mode… I have searched a bit but I haven’t found anything that suits me yet. If someone can help me, thanks in advance.

Sincerely.
