TIL that this trick is now in fact a single op instruction! t.co/pHTltIgvTp

Explanation behind fast inverse square root's magic constant 0x5f3759df. Is anyone still using it nowadays in their engines/games? If so, does it have any major impact compared to computing powers from 10+ years ago? h14s.p5r.org/2012/09/0x5f3759d

And that's not all! If you start reading commit messages from the beginning, you'll learn by how much each change improved compression ratio/speed on various test sets. Pure gold and excellent way to understand how things work in software! mastodon.gamedev.place/media/2

Not only is the Unity-updated crunch compressor faster, the commit messages are an excellent learning material and a way to see the author's thought process. Definitely worth sifting through! github.com/Unity-Technologies/


I've been working with games for almost 10 years now and having experienced coding gameplay, AI and porting to obscure devices, I am now focusing mostly on tech development: engines, tools, workflows and other things to make your life easier. I'm also doing some VR research and fiddling around with graphics, so boredom is unknown to me. Also: I like challenges and meeting other devs!
