it's like an unintentional horror game. why is there a child shaped robot in space? why is it acting cutesy? and why the hell does it want to go to earth?!

i am surprised at the reception of pragmata. from the moment i saw the trailer i was viscerally repulsed by the child-shaped robot. well, back then i didn't realize it was supposed to be a robot, since kids in videogames often look uncanny anyway. knowing it is in fact a robot gives 10x the ick.

yeah i know it's probably sad and cringe to say that at over 35 years old.
but it is what it is, that point in time was the apex of both enjoying the moment and having hopes and aspirations for the future in a way that hasn't been matched since.

not just "look back fondly on" but actually painfully miss it, in a way that is probably not healthy.
i'd give up everything to go to bed one night and wake up back in 2007 again.

while prepping that spherical harmonics post i was going through some of the old books on analysis and differential equations and the whole process reminded me just how much i miss my time at the university.

It's OK to compare floating-points for equality

New blog post! I really hope I'll get a decent amount of people mad with this one 😈😈😈

Genuinely there is more stuff to cover with respect to deringing, or how to organize and sample SH probes, maybe doing specular... But I'll let smarter people write on that 😆

shenmue crawled so yakuza could run

many thanks to @tomforsyth.bsky.social for taking the time to proof-read my infodumping. any errors in there are mine.

INTRODUCTION TO SPHERICAL HARMONICS FOR GRAPHICS PROGRAMMERS

finally done.

gpfault.net/posts/sph.html

doing the one offs is how you learn how to build the general system

my intuition is yes we do lose something, but it doesn't matter unless the image in question is very low resolution. every texel subtends a non-infinitesimal patch on your integration domain, but when the image is huge you can handwave that away.

Oh man what were you even working on

defining convolution through spherical harmonics feels... circular? I'm also not sure if it's possible because the nice formulas exist for symmetric kernels but I don't know about the general case

I'm just saying that even finding the simple formal definition of what it _means_ to convolve two spherical functions seems weirdly difficult

yeah even riemann sums on the sphere are weird because how do you compute the area of sphere surface patches? i almost had to write a whole section about it in my blog post but luckily there was already a really good explanation www.rorydriscoll.com/2012/01/15/c...

is spherical convolution (as in, convolving functions on a sphere) really such a niche operation? the only definitions i can find are all 10 pages deep in some ml papers OR on someone's lecture slides from 2015. you'd think the wiki article on convolution would at least mention something...

the internet has ruined us
i mourn my innocence

probably, inverted normals😅

still cooking... another one of those posts that got out of control...

doing the yearly hanami at the uw quad

I think "male loneliness crisis" is really referring to "male singleness crisis" :)
which could potentially be cured by hanging out with other dudes (the larger your friend group, the more chances there are to meet a partner), buut it might not be the most efficient way

ngmi. you should be running a dark software factories with 10000 parallel agents handling tickets for your agentic SaaS.

X Japan - Rusty Nail (Anime Version) YouTube video by Yoshiki

type of shit that you see on the tv or some vhs tape once, when you're 9 years old, and then spend your teenage and young adult years wondering whether it was some fever dream or implanted memory, until one day you stumble upon it on youtube

the point here is that uefn doesn't need a programming language

girugamesh 🤘

your renders are always so slick

tbh, it's probably a bit inflated because of some of the math begin split out into separate paragraphs for better readability. but by pure pagecount it's shaping up to be the record holder (current king is one of the assembly tutorials clocking in at 28 pages)

...and im still not done yet...
