The documentation states the function returns true or false
indicating if the polygon is 'front facing'. 'Facting' makes no
sense. It seems it was a typo to me.
oh, sorry. I just glanced quickly and all I saw was that you changed the initial lowercase to a capital, which would be inconsistant with most of irrlicht's functions. I definitely see your point about facing vs. facting, it probably is a typo. I'll look more closely next time.
You do a lot of programming? Really? I try to get some in, but the debugging keeps me pretty busy.
