I am in love with my latest pen/ink/paper combo. Will need to test more to know what is doing what as it’s all new: chou kuru ink on leuchtturm via a montblac starwalker I had custom ground to fine. So wet! So deeply black!

@c0de517e custom grinding, huh? I gotta look into that process. I absolutely love italic nibs but most are waaay too wide to be useful in day-to-day usage (best I've found is the smallest italic nib Pilot has)

It would be neat if there was a website dedicated to cataloging and evaluating common rendering techniques, focused on practical use a with straight forward explanations and reasonable examples for each entry and a discussion of tradeoffs.

@aeva I'd love this. And it's the kind of thing I'd love to contribute to, but I know I wouldn't be able to drive long-term 😔

I am excited to finally share our recent paper "Filtering After Shading With Stochastic Texture Filtering" (with @mattpharr @marcosalvi and Marcos Fajardo), published at ACM I3D'24 / PACM CGIT, where we won the best paper award! 1/N

@BartWronski @aras @demofox yep, I've done two work from home stints (one in 2010, another in 2020), and I burned out both times.

Aras, take care of yourself, it's easy to end up in a bad spot

About all the folks saying "come visit!" around here, every rendering team on the planet would love to have you show up at their office for a week and have random discussions over lunch.

You could really start the nerdiest world tour ever. And we'd all love it 😄

I made a voronoi diagram :3

jon_valdes ,
@jon_valdes@mastodon.gamedev.place avatar

@aeva @ruojake a nice trick you can use for drawing voronoi diagrams is to use the depth buffer. You draw a shape around the cell, and give each pixel a depth value based on distance to the center of the cell. Then let the depth buffer figure out which cell is closest. And you can have each cell compute distance however it wants 🙃

@aeva @ruojake and here I thought I was carrying some secret knowledge...

if a novice programmer can code something that runs in a safe language, then an experienced programmer can translate this program to optimized, high-performance semantics.

i theorize that the experienced programmer's job can be sufficiently automated, provided that we control the novice's language, without requiring silly differentiable algorithms.

jon_valdes ,
@jon_valdes@mastodon.gamedev.place avatar

@lritter the semantics are usually not where a novice leaves most perf on the table. It's on using fancy algorithms. An optimizing compiler won't turn a naive O^3 algorithm into an nlogn one

jon_valdes ,
@jon_valdes@mastodon.gamedev.place avatar

@lritter if you do that and you sell that service to companies, any bet we make will be a drop in the ocean compared with the amount of money you'll be able to make

@lritter under the current system, being able to feed oneself and the people one cares about sometimes requires moral compromises. But if you're free enough to be able to afford giving it away, you'll be forever lauded as one of computing biggest heroes 🙃

systematically confronting people with problems they are powerless to change is a form of torment. "raising awareness" isn't inherently good.

that said, if you happen to be powerless to change your tendency to systematically confront people, then i am truly sorry for bringing this to your attention, and i am asking you to disregard what was said in its entirety, and just carry on as you do.

@demofox@mastodon.gamedev.place avatar

Oh boy. I can now say there is a new family of noise textures dropping at i3d in a month that is higher quality than spatiotemporal blue noise, generalizes to arbitrary spatial and temporal filters, and we show significant benefit under motion/disoclusion with temporal filtering/reprojection for real time.
It was a collaborative effort between the 4 of us, but William Donnelly really knocked it out of the park, deriving a well motivated loss function, making it possible.
More details to come!

"If you make your own engine you'll never ship a game"

I'm here to tell you this is BS. Kitsune Tails uses a custom engine built on a custom framework all made from the ground up by yours truly. Neither of these were even remotely the bottleneck for development duration. Turns out that the thing that takes the most time when you're developing a game is all the stuff that is hyper specific to that game and can't be generalized anyway

Not to mention all the, you know, actual content that sits on top of the engine. I can write a json parser and serializer from the ground up in a day or two, but all the cutscenes I had to script for KT took many weeks

Then there's the fact that if I'd used an out of the box physics solution for Kitsune Tails I'm fairly certain I'd never have been able to nail the game feel it has, which is the most core thing to the whole experience

You don't have to make an engine but quit pretending doing it is the hard part of making a game. It fucking ain't

Corporations can be awesome at one place, and absolute hell-holes 10 meters away. Both of you can be right at the same time... and wrong at the same time too.

I've seen someone scream "Fuck Frostbite" into the void for half a decade after they had a terrible experience here. Meanwhile, other folks (including myself) were swearing this was the best company they had ever worked at. Both experiences can be true.

My takeaway: there's no single truth in a corporation

Burning bridges does carry consequences. Whether doing that is worth it is up to the person that feels hurt.

This goes both for Alan's relation with nVidia, and for your relation with Alan. Alan clearly feels hurt by nVidia, and feels the need to burn that bridge forever.

And now you feel hurt by Alan.

After a similar public attack on my team from an ex-employee, I understand this can feel unfair, tainting the reputation of the team, etc. He's saying your team are bad people, and that hurts. But attacking him won't make him hurt less, or change his mind about the team.

Time will help, eventually. Perhaps patience and understanding would help too

Hot idea: force employers to publish statistics about the workplace in ways that show data but don't deanonymize employees.
Things like:

  • average salary per job title
  • avg number of years of exp per job title
  • avg rating of managers by the people under them
  • a word cloud of stated reasons for leaving during exit interviews
  • many more things could be teased out.
