when i click ‘’quick‘’ of ‘’estimate normals‘’，it's too slow

[syly666]

It's a great honor to read your paper. But when i test "Autodetect planes",it shows no plane has been found. I try click ‘’quick‘’ of ‘’estimate normals‘’ ,then "Autodetect planes". It works，but why estimate normals cost so many time（more than 800s）. Thank you very much，If you can reply to me.

This is my test file. crop.zip

Hello. It's slow because it's currently doing it sequentially. You can speed up the process by enabling TBB for parallel processing. Refer to the file:

And uncomment the commented lines. Don't forget to link TBB to the project.
