Amiga Graphics | Discussion

Material Maker 1.6 is now available for download. It introduces controlled variations (a way of reusing subgraphs in different contexts and iterate on them), Aperture nodes ("wireless" communication in the graph) as well as many updates and bug fixes. rodzilla.itch.io/material-mak...

FragCoord v1.0! -Write shaders in WGSL, Slang or even HLSL (experimental) -Build shader sets. Curate collections for teaching, organizing and learning. -Invited creators can now co-edit shaders -And much more!

Here's Material Maker's showreel for March 2026. You will find all those materials (and many more) on the website. Please feel free to leave a comment on the video and let us know which material you liked the most! youtube.com/shorts/gtGlB...

Made and rendered in #materialmaker as background for a demoscene meetup flyer.

Dizem que vai haver outra Momentum? Sim, é verdade. Dia 23 de Março estaremos no GamingHub em Lisboa. Juntem-se a nós para mais um meetup da Demoscene em Portugal!

Introducing FragCoord: My ultimate shader editing tool!

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...

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

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...
