TiXL A powerful FREE software for generating visual effects and motion graphics for installations, live performances, and VJing. It is easy to learn, yet incredibly powerful.

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...

SIGGRAPH 2025 Materials Now Available: Recordings and Resources from Our Events

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/...

I will give a workshop on #materialmaker on Oct 4th in Porto. pretalx.softwarelivre.eu/fsl2025/talk...

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

Made a nice page for all my demoscene favorites.

Functional Raymarching compute.toys/view/2303
SDF rendering where 3D scenes are built through pure functional composition. There is no SDF function in the scene. Only main_image needs to change for every possible scene. Using SLANG

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

Shadertoy

Made a shadertoy with it shadertoy.com/view/wXX3zr

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

You may have heard of SDFs, but this is an introduction to actually using them in computer graphics!

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
