Hi Alex, Im Jin from Korea. I have been working on swift like 2-3 months, so everything are hard for me. I had made ply file on swift /cpu ( metal is very very hard to me.. so i made it with swift cpu ) I am trying to show my ply file just like your app. But I don't know how to do it. ( I had tried scenekit view to show ply, it was not showing ply file but obj file ) thanks for any kind of hints or codes.
