Brb something serious popped up

some roastie trying to get on his nuts through tinder

ive never studied it, but yea. it uses some floting point hack to pick the starting value

and then an iteration or two of newtons method

okay, i understand that now

https://en.wikipedia.org/wiki/Fast_inverse_square_root

on a parabola with roots at the sqrt

the comments are hilarious

there was some paper, linked to on that wikipage. someone makes a better one

they do some number crunching a find a better magic number

lol thats badass

@Nerthulas is no longer a part of our community

is it common for game designers, or any other programing discipline, to get mathementical breakthroughs due to pushing math to it's limits

no

just hacks?

3d games use math thats over a 100 years old

yeah

they're not pushing any boundaries

I mean it depends on your definition. It likely won’t be theoretical advances but they can innovate algorithms and numerical techniques

when you code a game,
you just do *what works* and don't give a shit about breaking the laws of thermodynamics

maybe that didn't come out right

is trump going to get impeached im not keeping up

lol

the are pushing hardware boundries though, and have a need for performance to be somewhat fast

They usually do that with sloppy hacks calling assembler code directly to manipulate the registers smarter than compiler would

That was mandatory in the old days to get decent graphics

anything interracial seems so unnatural and repulsive to me

seems like a fetish to me

well, it depends, some people do push the boudaries though,
but it's probably people working either for Nvidia, who look for workaround algorithms to speed things up,
or it could be someone working at Unity who is find some new funky way of doing raytracing..

i dont think they're pushing any boundaries. games are getting better cause the hardware people are making better chips

Algorithms are a type of math

No one can deny dudes like Knuth are gods

but it's rarely someone at Electronic Arts that will come up with some new math wiz kind of algo

Because most game devs are actually the lowest tier of coders

EA treats game devs like shit

yeah

95% of game devs have no idea how quaternions work. and probably not even matrices.

i almost got a job at nvidia

they just use them as black boxes

there was a black guy in the interview that I didn't mesh well with
