First I'd like to thank Casey for starting this series, have been following since Day 1, I've really benefited a lot from this, really wish there was something like this 10 years ago.
I've been rewatching some of the past episodes on topics that I'm totally unfamiliar with, and on day 94 Casey talked about light-linear space. He mentioned that it wouldn't make any noticeable difference with what he's doing in Handmade Hero, but are there any examples where this sort of gamma correction is necessary? Can someone point me to some examples where there is a problem with non-gamma correction vs gamma correction? 2D or 3D?
Thanks.
