Looking through the Cesium Unreal plugin it seems to me that the data comes in as a gltf model, but the database stores quantized meshes, which I understand stores the vertices as latlong+height. Where does the transform to object space coordinates for the primitives happen? Any chance someone could point me in the right direction?
If this refers to the conversion of quantized mesh to glTF, then I think that the cesium-native QuantizedMeshLoader class might be an entry point. Otherwise (or if further pointers are required) maybe someone can provide additional hints.
That’s a great detail, thank you for sharing. Will look a bit closer at it.
