Coordinate question about Cesium and Babylon

[chengyinl]

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:

Integrate BJS with CesiumJS

Demo here. Thanks to 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:

Incorrect rendering of model geometry after changing the position on the map (mapbox + babylon.js)

Maybe that can help: Babylon in Mapbox Layer - #11 by Kun_Liu MapBox GL to BABYLON Camera Projection - #16 by sable There are other posts in the forum regarding mapbox integration (seach for mapbox). Also, try to create the engine with useHighPrecisionFloats:true and useHighPrecisionMatrix:true. See EngineOptions | Babylon.js Documentation
