Hey there guys, thank you very much for the comments!
riuthamus, thank you very much man. More is coming
Cozzie, thank you buddy, much appreciated!
Great find, Cygon! This is very interesting. I'm glad gamedev.net has so many programming-savvy folks.
I've mailed Emil Persson - the author of the post I'm referencing and I'm going to go through all the links you've shared 'cause it seems like a great read and it might inform some ideas/explanations. The paper and his post are all the way back from 2009 so I'm wondering if things might've changed since then.
Still the advice on triangulation doesn't seem harmful to me and if anything it still feels like it could be doing some good, just for the wrong reasons. Would be interesting to get to the bottom of this though. Thank you very much once again!
