As with many CG concepts, implementations can be very different to the ref. + the ref often doesn't bother efficiency and tweaks. For Gabor noise, a ref implem was just posted here: shadertoy.com/view/slj3W1 NB: all ingredients have been revisited here: inria.hal.science/hal-02104389

Qui saurait me retrouver le nom de cette musique (tirée d'un film/série il me semble) à 18'36 illustrant un sujet du JT de 20h d'hier soir ? www.france.tv/france-2/jou...

Je trappe de drôles de truc lors du désherbage de la bibliothèque du CE de mon labo...

Rising Sun, from my windows (Grenoble, France)

pinky morning (hidding Vercors)

currently 200 games (most often playable, +a few demo) in #shadertoy ! ;-) shadertoyunofficial.wordpress.com/2017/11/11/p... ( the last one is Ricochet robots / Robot reboot )

* Working in vorticity space is so convenient: div=0 per construction 0 everywhere but on vortices ( → open space easy ) * With Lagrangian (ie. partics) & Verlet integration: ultra-precise and no diffusion * With 1D-particles(=filament) in 3D: magic ! inria.hal.science/inria-004021...

Publishing your @Desmos Graph gallery: Now with 2D and 3D graphs ! Even more convenient with the new always up-to-date URLs ;-) . Several options in the the script (e.g., default: not displaying untitled tests). github.com/FabriceNeyre... e.g., mine: evasion.inrialpes.fr/~Fabrice.Ney...

Real-time online vortex-flow simulation on #shadertoy (go fullscreen for empty space filling). NB: you can dynamically paint markers. shadertoy.com/view/wXcXDM

Le duct-tape est vraiment la solution à la moitié des problèmes. ( l'autre moitié étant résolue par le WD40 😀 )

Hardware virtual textures look like a marvelous tool for large terrains or volume compression. Alas, they are in a sad state in terms of performance and usability. And strangely, the (very bad) binding perfs varies a lot with the driver. → read here: hal.science/hal-05138369 @rcmz0.bsky.social

Do you like voxels and implicits' representations and wish you could animate them in real-time? Now you can! Check out our article: "Real-time rendering of animated meshless representations" to know how: hal.science/hal-05095359 Shout out to @pacomeluton.bsky.social for this fantastic work!

Wanna see how to speedup x12 flyover procedural FBM worlds (possibly animated) ? → Check Mathéo Moinet & I new Eurographics paper "Fast sphere tracing of procedural volumetric noise for very large and detailed scenes" (tuesday) inria.hal.science/hal-05046040 (paper, video,+slides soon)

sort of voxeltoy game :-p

hier en début de soirée: ( 1er janvier, à partir de 18h20 ) www.skaping.com/chamrousse/l...

environ 100m d'épaisseur de neige recouvre Grenoble, plus rien ne dépasse :-D

Grenoble: La bastille est juste au dessus des nuages ! www.skaping.com/grenoble/bas...

Fog never lift today, and is now illuminated from below by Grenoble. www.skaping.com/chamrousse/l...

After the snowfall, all directions from my flat at Grenoble.

Demain l'EducNat ? :-D

Argh, apparently several followers of my various twitter accounts ( pro, in English, perso/skeptic, in French, etc ) discovered this Bluesky one and follow it, despite not split (yet). But for the moment my activity is still mostly on twitter+facebook+usenet ( ok boomer here :-D ).

( par Pascal Gros. pas trouvé de site web d'origine ).

I set in my profile that I wanted only english+french. Why do I receive tons of posts in german ?

Jean-Louis Racca est mort vendredi 29 décembre 2023...

Mais pourquoi BlueSky me fait soudain une majorité de recommandations en allemand ???
