I want to know how cesium gets the vertex information of the inclined model

I am a graduate student doing webgis related research. The current research progress needs to obtain the information of each triangle block of 3Dtiles (ps: oblique photographic model), and then calculate the normal vector of each triangle patch. what are the APIs corresponding to cesiumļ¼Ÿplease. :smiling_face_with_tear:

Hereā€™s the documentation for the top-level Cesium3DTileset and for the individual Cesium3DTile.

What you describe is not the typical use case of the CesiumJS API, so you may need to dig into some of the source code GitHub.
