How to get all vertex coordinates and triangles of a polygon or a corridor after it is clamped to ground?

If you are using entities, they abstract away the lower-level graphics API.

But if you are using groundPrimitves, you should be able to access the underlying geometry instances, and generally have finer control over how the geometries are rendered.
