amazing talk. they decap and also reverse the custom roland jp8000 dsp chip, make a faithful emulation plugin, and along the way reveal the famous supersaw as simply 8 detuned, aliased (!) 2x oversamped naive saws. youtu.be/XM_q5T7wTpQ?...

2 weeks until our Inércia 2025 event takes place! Checked the program schedule? Finished those bridge theme inspired entries? Registered to attend? Great! Now help us promote the event to the rest of the digital art community out there! inercia.party

Second Reality now has a fully portable C++ version! Thanks to the work of @conspiracy.hu and JSRProductions You can even run it on your browser! jsr-productions.com/secondrealit... Here is the C++ source github.com/XorJS/Second... And the web page jsr-productions.com/secondrealit...

Looks like someone took our ball and ran with it, and continued with a fully portable C++ port of Second Reality - including a browser version! www.jsr-productions.com/secondrealit... Finally we can replace DOOM as "the thing you run on things"! 💪

🎃

Saturday 6th of December we will host a workshop given by the developers of TiXL, teaching Inércia visitors how to use TiXL for generating visual effects and motion graphics for installations, live performances, and VJing. tixl.app You're going to miss it?

Mais uma Momentum, o nosso evento mensal está quase aí! Dia 1 de Novembro, a partir das 15h, junta-te a nós para conheceres a Demoscene em Portugal!

Made in #MaterialMaker you my custom nodes Shadertoy is here shadertoy.com/view/3XjyD1

The theme for Inércia 2025 is bridges! Yes, those small and large systems carefully engineered to bring and maintain connectivity. Technological bridges, cultural bridges, social bridges, circuit board bridges... Get inspired and show us what bridges mean to you 6-7 December.

Estivemos na Festa do Software Livre e já podem ler um report do jae sobre a participação no evento scene.pt/fsl/events-r...

Recordings for all of the Slang-related sessions at this year's SIGGRAPH are now publicly available on YouTube! Check out the Slang blog for links to recordings and session materials here: shader-slang.org/blog/2025/10...

Uploaded my new version of Material Maker lib with more than 120 nodes, especially dedicated to SDFs Now for #MaterialMaker 1.4!!! github.com/paulofalcao/... A Shadertoy in 1 minute 😁

I will give a workshop on #materialmaker on Oct 4th in Porto. pretalx.softwarelivre.eu/fsl2025/talk... Made this for it shadertoy.com/view/3ffcWl

Mais uma? É mesmo! Apresentamos mais uma Momentum, dia 27 de Setembro em Almada! Aparece e vem conhecer a demoscene em Portugal!

Most of the slides and course notes for the SIGGRAPH 2025 Physically Based Shading in Theory and practice course are now online, with more to follow: blog.selfshadow.com/publications...

Próximo Sábado em Almada, dia 19 Julho temos Momentum com churrasco, quem quiser vir socializar com demosceners, falar sobre o que tem feito de arte digital, ver demos e/ou reparar electrónica são bem vindos. Tragam comida/bebida para partilhar. Apareçam no discord para mais info

This paper suggests that the length of AI tasks is doubling every 7 months metr.org/blog/2025-03... There is also a research that speculates about possible AI futures ai-2027.co I’m more toward the idea of diminishing returns over time with AI, but…

Made this using my custom nodes in #materialmaker

Somehow ended up doing a shadertoy for webgpu shaders with a way to specify any pipeline configuration in that same text area. Like a portable webgpu real-time pipeline shadertoy or something

Já no próximo Domingo, em Almada. Mais uma Momentum, a meetup mensal da Demoscene e arte digital em Portugal. Aparece!

NEW GM Shaders: Signed Distance Fields mini.gmshaders.com/p/sdf You may have heard of SDFs, but this is an introduction to actually using them in computer graphics!

as a continuation, a recent documentary about the Timex plant in Portugal where ZX Spectrum and Timex computers were made It has English subtitles for your enjoyment

I made an attempt to create this kind of material. Also, this is the first shader I'm posting about on this new Bluesky account! www.shadertoy.com/view/Wfs3RN

Caso não tenham visto ontem na TV Linear, aqui fica o melhor documentário Português que vão ver este ano

I got tired of people relying on other people's code to build demos (or games for that matter) so here's a tutorial in 40 steps and ~400 lines of C++ on how to build a renderer (with music) in DX11: gargaj.github.io/demos-for-du...

Hi Bluesky! With the sudden closure of Jumpship, I'm looking for a new role I'm looking for anywhere I can make beautiful things with code, my ideal role would be a mix of graphics programming, technical art, and gameplay programming (or anything else interactive)

A não perder!

One of the tedious aspects of modeling SDFs with raw shader code is adjusting the position of objects, so I'm adding transform gizmos into my tool They write changes directly to the shader on disk, so I don't need an external object hierarchy tdhooper.github.io/offline-shad...

243 chars of #GLSL: vec2 p=(FC.xy-r*.5)/r.y*mat2(9,-2,2,9),v;for(float i;i++<50.;o+=(cos(sin(i)*vec4(7,4,2,1))+1.)*exp(sin(i*i+t))/length(max(v,vec2(v.x*(3.+snoise2D(p+vec2(t/.3,i)))/1e2,v.y*.21))))v=p+cos(i*i+t+p.x*.2+vec2(0,11))*3.;o=tanh(pow(o/3e2,vec4(1.5)));

So... instead of doing anything useful today... I made Blender VSE timeline run Doom. www.youtube.com/watch?v=Y2iD...

#DOOM is now playable in a PDF file 🎮

Metallic Snowflake shadertoy.com/view/X3VcDK Made in #MaterialMaker for a flyer for a local demoscene event Momentum #19 Added DOF in my MaterialMaker path tracing render node for this.

#Blender add-on is on Github 🤓 it's raw and messy, but it's online 🥳 github.com/leon196/blen...

Because I don't have enough problems in my life, I decided to make a custom render engine in #Blender so I can code GLSL shaders and render them nicely

I've done one article for the shader advent 2024 : Demystification of つぶやきGLSL ! github.com/mrange/shade...

Still building up!

Last month I presented Gigi to the Graphics Programming Conference in Breda, talking about the history and motivation of Gigi, as well as implementation details. My talk, and the rest, are now available on youtube. The conference was amazing. www.youtube.com/watch?v=MgCR...
