comment Help understanding matrix math in whitening transformation proofs
I added a note about the matrix math mistakes and that they will be fixed in the original article. I still want to know how that last line in the proof is justified.

comment Help understanding matrix math in whitening transformation proofs
Thanks for the great answer. I actually noticed the same thing in the article by Andy Jones and wrote an email to him. He is going to fix that. I feel like that could be fixed.. for instance by applying the whitening matrix on the right of X.. The fact that both articles make the simplification I mentioned above is what is truly bothering me as I feel like I'm missing something obvious.

comment Finding the distance of a point from many triangles in 3D space
Agreeing with MvG. Octrees would allow you to reduce the number of comparisons you'd have to make logarithmically (assuming your triangles are separated, and if not, then they are all close)

comment no module named pymongo
What does the command "which python" say when you run it. That will tell you what python you are using from the command line.
