Hi there,

I have a polygon entity drawn on a custom terrain(served through Cesium ion) that looks like this:

Looking closely:

I can see the overall polygon is composed of multiple tiny triangles. I would like to know how I can access the vertices of these tiny mini triangles.

Why do I need to access the vertices? I want to calculate the total surface area of the polygon and I’m trying to use the approach of summing up the area of the mini triangles that makes up the entire polygon.

Thanks.
