I am looking for an example of preRender event subscription to generate a custom animation of a 3D-Model Entity?

I read on the community that it should be the preferred method compared to implementing a custom render loop but there is no example to go along with that advice…

Logic/code driven animation examples are almost non-existant in Cesium by comparison with Three.js and Babylon.js, could anyone please prove wrong on that 🙂 ?

Thank you!
