Precision about different methods to get 3D coordinates

So far, I have tried using the PnP solution for the sanity check, but the results of both functions are very erroneous and just don’t make sense at all.

Can you share a Sandcastle example reproducing this issue that we can run? See instructions here: How to share custom Sandcastle examples - #3 by omar. I’m curious how you’re evaluating the accuracy here.
