I have a niche and technical question for Graphics community. Context: 0. For integration, when you have an HDRI latlong. 1/5

Still working on DearWidgets (github.com/soufianek... DearWidgets ) here some features not yet published: * Up Vector * Spline Slider 1/5

Let's say I want gradient or an image in Glyph/Font (ImGui only so UV and VertexColor only!). That's mean I need to have triangulated mesh with preserved UV from bunch of quadratic curves. 1/5

Finally! All of that for just showing a dynamic illustration in app! Bunch of algorithms was implemented for this dynamic illustration. WIP version available (github.com/soufianek... no LaTeX yet!) Depends on ImPlatform for custom shaders github.com/soufianek... 1/4

Finally having Gradient, Ligature, kerning, Right to Left working. 1/4

I think I found a new Rabbit Hole. Adding support for colored font (SVG and COLR v0):

It cost me 3 ALU ops, but all fixed now all exotic fonts works.

forgot to share the link to the github for: bsky.app/profile/souf... github.com/soufianekhiat/

My attempt of rendering font with Slug Algo from the reference implementation of shaders (thanks Eric Lengyel). Still having issue with thin stroke of some font, suspect my adaptative sampling. 1/3

Qaws (قوس) Arabic for *arc*, *bow*, *curve*. A dependency-free C11 library for creating, evaluating, sampling, traversing, and inspecting parametric curves and surfaces in 2D and 3D. A dependency-free C11 library for parametric curves and surfaces in 2D/3D. 1/13

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

RDV ce soir avec @beammyup.bsky.social et @yoriculaire.bsky.social à 23h (Paris) / 17h (Montréal) pour continuer le blogpost de Pema sur les mipmaps pema.dev/2025/05/09/m...

Do you feel lonely? src: en.wikipedia.org/wik...

On retrouve @yoriculaire.bsky.social ce soir à 23h (Barcelone) / 17h (Montréal) / 14h (Vancouver)! On souhaite du repos à @beammyup.bsky.social et on la retrouve lundi en live avec @soufianekhiat.bsky.social !

Tic tac! Tic Tac! ⏳On se retrouve dans moins de 9h pour un stream de qualitay avec @beammyup.bsky.social , @soufianekhiat.bsky.social , et @yoriculaire.bsky.social ! Rdv sur Twitch à 23h heure de Paris, 17h heure de Montréal, 14h heure de Vancouver!

RDV à 5pm EST / 23h CET avec @beammyup.bsky.social et @yoriculaire.bsky.social pour commencer la lecture de "IBL-BRDF Multiple Importance Sampling for Stochastic Screen-space Indirect Specular" de @soufianekhiat.bsky.social!

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...
