Introducing Alwan (ألوان): A pure C colour science library 100+ RGB spaces, 30+ colour spaces, ACES 1.x & 2.0, spectral processing, CAMs, ... Zero dependencies. Unit tested against colour-science f32 or f64 floats. Looking for reviewers before public release (DM for repo). 1/15

I will release the first official #ImAnim 1.0.0 github.com/soufianek... github.com/soufianek...#ImAnim 1/10

I'll add debug timeline and in app documentation for the next version of #ImAnim.

I've been reading about color science for my book and I wanted to verify the claim that Oklab gives better linear gradients than the otherwise excellent "CAM16-UCS" color space. And yes, its gradient obviously too desaturated in this test. Oklab's ancestor "IPT" also works fine.

Want to talk about ImAnim: Animation Engine for Dear ImGui (@ocornut.bsky.social)? (: news.ycombinator.com/item?id=4610... github.com/soufianekhia... 1/8

Much more examples available in the demo project. Next step perf! * Lazy eval: cost only after the first execution of an animation * Culling!

My team is hiring. Let's join Battlefield 6 Rendering Team (Montréal). jobs.ea.com/en_US/ca...

The work continue to deliver the best experience!

After years of work, I am proud to show what we achieved with our rendering team between @CriterionGames and @EA_DICE and the rest of the world. youtu.be/pgNCgJG0vnY

I didn't have time to fully update the code for #GPUZen3 on #Unity 6 LTS. So for now I'm sharing illustrations code and Jacobian derivation notebook (#Mathematica). Plus some illustrations I did not use in the book chapter. github.com/soufianek...

#GfxFunFact There is a museum (@CentrePompidou) created for gfx people, with a lot challenges. Like OIT challenges 1/5

#GfxFunFact: In Paris, Sphere ball for Reflection Probe validation are place in grape for convenience.

#GfxFunFact: Ikea design this ceiling light cover on purpose to slowdown rendering.

Fun fact during Christmas all rendering became slower, here exemples of light count, occluders, and transparent they dare using.

For my french community: Here's a cool french-speaking www.twitch.tv/shiniesandsh... channel where they go over recent graphics/rendering academic papers in a gentle step by step manner.

I have a chapter on the next #GPUZen "IBL-BRDF Multiple Importance Sampling for Stochastic Screen-Space Indirect Specular" - IBL-MIS-SSSIS - www.amazon.com/dp/B0DNXNM14K

Let's wrap up this lovely week with a nice technical post This is the "case study" from my Masterclass at GPC, where I apply a series of optimizations to improve the effective bandwidth of a 3x3x3 blur (a proxy for a huge set of operations on volumetric data) Check ALT text for (a lot of) context.

"Occupancy Explained" GPC 2024 presentation slides are now available online: gpuopen.com/presentation..., they are missing notes though so to fill in the gaps I recommend this great post from 2023: gpuopen.com/learn/occupa...
