When i promote my project about Cesium with Babylon,hanppened to two problems.  
First,I import a .gltf model in Babylon`s canvas but if I move the camera,the model maybe the scene begins jitter,which is the reason that Babylon synchronize the coordinate in Cesium.  
Secondly,i try to add a billboard in a point in model,but the billboard appear out of the earth of Cesium,I think maybe the coordinate question about Cesium and Babylon.  
So may someone can set up a planto resolve this question,a code in github will be better

Maybe that can help:

> [Demo here](https://github.com/Hypnosss/cesium-babylonjs). Thanks to [https://cesium.com/blog/2017/10/23/integrating-cesium-with-threejs/](https://cesium.com/blog/2017/10/23/integrating-cesium-with-threejs/), I made something similar with BJS. Though with ugly codes, in case anyone need it, I’m going to share the demo.

Also, regarding the jittering, you can try using the `useHighPrecisionMatrix: true` option when creating the engine. See for eg:

Also, try to create the engine with useHighPrecisionFloats:true and useHighPrecisionMatrix:true. See [EngineOptions | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/interfaces/BABYLON.EngineOptions#useHighPrecisionFloats)
