Algorithm for Spatial operation such as STConvexhull

It seems it offers a convex hull operation.
Is there any way that I can see the algorithm source code that implements the operation? Or anyone knows which algorithm it uses like Graham Scan, Monotone chain. etc.

    Hi @Park,Kyuseo ，

    MS official document did not mentioned the algorithm for spatial data type. Such as STConvexhull, you can check this from MS offical document STConvexHull (geography Data Type). I also search this from google, but did not find the related information.

    If you want to know that how to use the spatial data, you can get this from MS document. Such as STConvexhull, refer to MS document Examples of using STConvexHull().

    Best regards,
    Cathy
