(author of the article) 100% agree. As others have said, a good graphics programmer works with tech artists and artists. Frankly, graphics programming is largely a role of service to enable those people to do what they want to do, or help c

Yeah. Sampling bias is fixed with Cranley Patterson rotation. For real time rendering, blue noise is the thing to use though. At low sample counts you can't converge so you should hide the error perceptually instead.

This talks about that more deeply and is by the same author (me) :) https://blog.demofox.org/2020/07/26/irrational-numbers/

Here's the source. Nathan Reed references a jcgt paper, which references a paper form 2012. https://www.reedbeta.com/blog/hash-functions-for-gpu-renderi...

Game development tends to make code more in this style, half way between C and C++. The reasoning of this is primarily the need to avoid hidden costs in the STL, but to be honest is also just momentum & culture :)

Fixed, woops.

Nice improvement!

Plus notice no mistakes were called out. It was just "don't buy parts from amazon".

Fixed this typo and i get what you mean how "one is not like the other" in the title.

Heya ladberg: * Were you doing direct light sampling (next event estimation)? If so that would explain it. It's the most naive path tracing you can imagine, so it's easier to understand. * Or, it might be how shadertoy is vsync li

See step 1 of the 3 step bulleted list, but yeah, it generalizes to 2 steps with a shared initialization value. Maybe worth noting that if your world has some known starting state (eg after map load), it might be worth the client and server

I hear you. It's hard to know what a good benchmark would be. Do you have any ideas for what you'd like to see measured and possibly what it's compared against?

Gamma still exists! Check out this really nice article for more info "The rehabilitation of gamma" https://poynton.ca/PDFs/Rehabilitation_of_gamma.pdf

you are totally correct. u16 is more than enough (as is u12 apparently!). F16 is also sufficient. I'll update the text to point this out.

"hair cells in the ear" isn't how hearing works. That's how balance works :/

Does this source code help you much with that? It only deals with wave files but can read / write 8, 16, 24 or 32 bit wave files, at whatever sample rate, with however many channels. I really wish someone would make a header only C++

By playing a sound faster I mean changing it's sample rate, without doing anything else.

I'm the author and didn't make this post on yc, but yes, the implementation is in 680 lines of standalone c++ The point of the article isn't about c++ or why it's a good language for doing this sort of thing, but I'

I wonder if the hacker news algorithm looks at the people who make the post to know if it should be promoted or not? One thing I have noticed is that when you post things, they get a lot more attention than when I do hehe. Thanks for that (
