Big thanks to @flohofwoe.bsky.social for sokol_app — made it easy to keep github.com/Geolm/onedraw examples small and clean, no extra dependencies. Super smooth setup. Only thing I couldn’t find was a way to create sRGB backbuffer on macOS (did I miss that in the docs?).

Excuse the coder art — this GIF shows the tile culling debug mode. Blue tiles are the ones that make it to the rasterizer. Notice how the interior of hollow shapes is efficiently skipped.

You can have look at the code and documentation here:

Testing an approach to break a quadratic bezier into small SDFs:

Blue: straight lines (oriented box SDF)
Green: “pie” caps connecting lines
Red: arcs

Faster than a full bezier SDF, though tricky with large stroke widths.

All done with my open-source GPU renderer github.com/Geolm/onedraw

Hello everyone, I wrote an extensive documentation on the GPU‑driven 2D renderer I’ve been working on.

Check out the overview here: github.com/Geolm/onedra...

Looking for early testers for onedraw, my GPU-driven 2D renderer built with Metal. Feedback before release would be super appreciated 🙏

Another test for my upcoming 2D GPU-driven renderer: 5000 oriented, rounded boxes with transparency.
All alpha blending is computed in-shader.
Everything on screen (UI, text, shapes, etc.) is drawn in a single pass, writing only opaque pixels.

Testing the smoothmin operator (iquilezles.org/articles/smin) in my 2D GPU-driven renderer. Performance takes a small hit, but the k-value has to be considered for binning — high k lets circles blend even when they don’t touch.

Just released a side-quest project: leanUI — a super-lightweight, dependency-free immediate-mode UI library in C99. Animated widgets and sleak design github.com/Geolm/leanUI

Few months ago I've started a hobby project : a 2d sdf editor. I wanted to sculpt a sdf without writting shader code. It's still the very beginning but you can have a look at the github page github.com/Geolm/Toodee... I'll try to post videos and screenshots in the future
