We're trying to move away from Cesium Ion, and our proposed solution for terrain is to use MapTiler's terrain mesh (specifically terrain-quantized-mesh-v2) with CesiumJS. The problem, as far as we can tell, is that MapTiler's terrain mesh is measured in EGM96 elevation, however CesiumJS seems to assume that the terrain mesh is measured in WGS84 ellipsoid height. MapTiler's sample code on how to do this is incorrect, in the sense that the displayed terrain mesh doesn't match reality, sometimes by up to 60m. A search reveals that we're not the first to have noticed this. There are a few not-easy ways to solve the problem, but has anyone worked out an easy way? Oh, the sampleTerrain and sampleTerrainMostDetailed operations also don't work, but one problem at a time.

I'm investigating my options for local hosting test GIS data for use with Cesium front ends. I have seen this project: Cesium Terrain Server but it seems quite old. I thought I read somewhere that Cesium can use OpenGIS Web Map Tile Service servers. Can Cesium front ends (CesiumJS, Unreal Plugin etc) be used with servers that implement the OpenGIS Web Map Tile Service standards?

I am looking for JavaScript libraries that allow you to visualise cityJSON (https://www.cityjson.org/) data. I am currently using cityGML with Cesium JS (https://cesium.com/platform/cesiumjs/), but would like to switch to cityJSON, due to its reduced file size and easier-to-read structure. Any hints?
