Good question @perhac - this is actually an open issue in the Cesium Native repository that we hope to tackle. As @Timothy_Moore mentions in that issue, his vsgCs project is a good starting point for seeing how Cesium Native can be integrated with your application. You might also be interested in our Rendering 3D Tiles guide that’s part of our documentation, which gives an overview of how Cesium Native and the implementing application interact. Of special note is the section at the bottom, “Implementing 3D Tiles Rendering,” which is a short overview of the steps required to integrate Cesium Native.
