@fnkylabs @ID_AA_Carmack We open source and maintain quite a few open source repositories, with permissive licensing. Check out github.com/orgs/electroni…

@ID_AA_Carmack There’s no way EA did something “for the people”. There’s gotta be an offer wall buried in there somewhere

I’m very happy to see more classic game source code released! I was always a little disappointed that the example of Id Software wasn’t followed by more companies — clearly, it was a Good Thing for us. The culture of game dev is a bit disjoint from broader open source dev in some important ways that influence things like secrecy and user visible polish versus technical debt.

🚀 Exciting news! SEED @EA is expanding with a new endeavor. 🌟 We're pushing game mechanics, storytelling, and interactive wonders to new heights. Join us in roles like Game Design Director, Lead Software Engineer, and more. 🎮✨ Curious? #latestJobOpenings" target="_blank" rel="nofollow noopener">ea.com/seed#latestJob…

SEED’s Chris Lewin delivered this terrific presentation at SIGGRAPH 2024 a few weeks back. It’s about a novel formulation of MPM that is stable at any time step while remaining easy to implement. Check out the video and download the paper! ea.com/seed/news/sigg…

@codemullins Once I was doing a live demo to a large part of the company, and all of a sudden the code didn't build. That day clicking yes saved my butt.

Has anyone ever intentionally clicked Yes here?

Gigi enables rapid prototyping of new rendering algorithms, and efficient porting to game engines. At SEED and Electronic Arts we use this to accelerate research and streamline integration into multiple engines at once. Gigi, developed by Alan Wolfe, is now open source.

@tom_forsyth @kenpex @BrianKaris surfcache 🙂

@kenpex @BrianKaris May I suggest the compromise term "irfels"?

Personal annoyance in terminology. A surfel en.m.wikipedia.org/wiki/Surfel is an element of geometry. The term you are probably looking for is (ir)radiance cache. 100s of papers about them since 1988. Each element is called an irradiance cache record.

@jarek_rozanski @jdnoc Something like a SuperMicro 825 or 826 can run almost silent with the right PU and PWM setup. That has redundant power supplies, and if you have even an entry level UPS you have stable power. There are used 825s on eBay for around $150.

Building out a data scraping operation. $500 per month? Or $500 once for essentially the same thing?

@AllegedlyMiri Firewatch The Witness

@nsobject @VinciusMedeiro6 It used a custom Global Illumination light baker from Illuminate Labs. One of the reasons it holds up well is that all lighting is ray traced and baked to lightmaps. It puts limits on how dynamic the geometry can be, but it's hard to beat in terms of quality.

@VinciusMedeiro6 oh wow, always thought it was frostbite. I’ve finished it so many times and it still surprises. What a game🙂‍↕️

Replaying Mirror's Edge, I haven't touched it in years and man this game's vibes and feeling are something else, love it.

@SebAaltonen It might not really matter. Even if we plateau LLM development there is untapped potential in 1. Empowering them by connections to other systems, VLMs 2. Breaking up problems like humans do We may just be scratching the surface there while focusing on larger and larger models.

I just want to remind people that we don't have proof that LLMs will lead to AGI. LLM is a network of information. They do very well if the task is close to their training data, but do very poorly in simple tasks that are not in their training data. Information != intelligence.

@iquilezles That's the killer app everyone in the space is working towards. Apple and google have an edge here in that everyone's lives are on their phones, and they have email and search. Microsoft is trying to reduce their information disadvantage with Recall.

@iquilezles It's about Ai having enough information about your life to become a useful assistant that can anticipate your needs and perform mundane tasks you'd rather not do yourself, inside and outside the computer. Not saying this is a good way to go about it, but that's Microsoft's angle.

@SamSmith2049 @raroni86 I'd start with this raytracing.github.io on CPU, then a simple DX11 computer shader version of the same.

@raroni86 I’d like to make something like this for fun, where do I start? (I’m studying math, CS, and physics)

ReSTIR can be regarded as a clever form of path guiding. My hobby implementation uses only 1/8 ray per pixel and ReSTIR still does a decent job of "finding" the small solid angles of indirect light even as they move (admittedly, this geometry is trivial but the lighting isn't).

GIBS ray traced GI is finally in the wild. It has been a great collaboration with SEED, Frostbite and the College Football team. Thanks to the great artists and lighters at CFB for making the tech shine.

@ID_AA_Carmack In off-line VFX yes. For real-time, ML deformers can learn from high-quality off-line generated examples and are efficient enough for games to give the perception of complex deformations, but in that case you still have to animate the character through other means to get the pose

Have CG art tools gotten to the point of modeling all the muscles in a human realistically, so a lot of the skinning and animation would be parametric variations on “baseline human” rather than free form constructions? I have occasionally advocated for that — some would complain of a loss of creative freedom, but like physically based rendering, it would probably wind up both looking better and being easier to work with. It would probably be hard to start an ambitious project around it today, because it feels like generative AI may be a faster path to the goal than conventional modeling.

@SebAaltonen That was a short summer!

Helsinki currently looks like this. 15cm snow in one day. Most people already switched to summer tires. I am WFH today. Impossible to bike in that much snow and public transport has issues...

@turanszkij Nice. How many rays per probe per frame are you sending?

Added multi-scale mean estimator to DDGI (also used in surfel GI), this makes it faster react to lighting changes. And now it also uses real-time BC6 compression.

@davepl1968 Love the smooth scrolling.

My real PDP-11/70 panel booting RSX-11M... with audio :-)

@bkaradzic @PottuVoi @seed Thanks, should be back up now :)

@staerlor @PottuVoi @seed FYI:

Part 3 of Alan Wolf's Machine Learning for Game Devs series is out, again complete with code and now a youtube video! youtu.be/sTAqWRsEiy0 check it out on EA @seed's blog ea.com/seed/news/mach…
