But, can it work without GPU? All native toolkits have fallback to software rendering. I do not uderstand what is gained, cpu was good enough for that since Windows 95 era? Just do not redraw every frame like in games but retain instead?

I'm excited, and will try this! Its provenance speaks loads, as Blender is a beacon of software design, open-source or otherwise.

I'm an EGUI fanboy, but am looking to truly compare it to other things, especially non-immediate mode. I have no gripes with EGUI, other than it seems to create an application size floor, and I suspect memory use could be better. It has never blocked me, including for complex applications with GPU rendering etc.

Blender is peak OSS. I'm in! Will give this a shot for my next limited-scope application. I'm also experimenting with GPUUI.

I will try Slint if I ever do embedded with a full GUI.

I will poke at this, because I saw the same sentiment in a HN thread yesterday: >" You write Rust or React and want a native desktop UI without shipping a browser." You don't need to ship a browser to do GUIs in rust. Some people do, and justify it through comparisons to Electron (Tauri) - I suspect this is a pushback against that?

Another thing I will poke at from comments: If you're going to dismiss this as a non-native UI and therefor inferior: Post specifically what features your OS-native toolkit or OS conventions have that won't work here. (Is it hotkeys, color scheme, a Je-ne-sais quoi? What OS specifically? My pet theory is these are all MacOS users, but I'm not sure)

This is cool. But can I write the UI in an XML file?

Nice. I have my own GPU GUI toolkit I'm satisfied with and developed because I did not want to have yet another imgui looking app that required gpu accelerated UI toolkit.

But, if I did not invest last two years into my own toolkit, I'd definitively consider.

Those numbers look very impressive, I'll try it in some projects

I have the same idea 10 years ago. :D I am so happy seeing that somebody was capable of making it. I always admire blenders UI and all the work developers did on making it.

> The GPU renderer is opt-in: Direct3D 11 on Windows (gpu/intern/gpu_d3d11.c) and OpenGL 3.3 core on Linux (gpu/intern/gpu_gl.c).

Direct3D is at version 12 on Windows[1].

What tech on macOS? OpenGL?

Nice! I've been waiting for someone to do this for a long time. Now I'll just need to wait a bit longer for someone to apply this to FreeCAD. Boy oh boy!

I have been remaking a Blender style UI in Kotlin for my Umamo project because I love Blender's UI that much.

I think I will keep going with my own efforts, but this looks nice!
