How to convert a large range of models

CesiumJS

I plan to convert a long road model to 3dtiles. What should I do to make it fit the terrain?

In what scenarios is Cesium_RTC generally used?

I think the way to do this would be if your model coordinates were in a specific projection, so perhaps defined as longitude/latitude/height, that way the road can be “straight” in this project, with height 0 throughout the model, but when tiled with Cesium ion it can be correctly displayed adhering to the surface.

Cesium ion doesn’t currently supporting reading models in such coordinate systems but here’s the feature request for this that you can follow: https://github.com/CesiumGS/cesium-ion-community/issues/271.
