Тайна Intel i740 — самой экзотической видеокарты из 90-х
Ранее я часто рассказывал об особенностях видеокарт из 90-х. В рамках прошлых статей, мы успели с вами рассмотреть внутреннюю архитектуру 3dfx Voodoo, узнать о кастомном графическом API в S3 ViRGE, и даже написать свою собственную небольшую демку под видеокарты из 90-х. Вместо рассказов о GeForce 256 и ATi 3D Rage, в сегодняшнем материале мне хотелось бы поговорить о видеокарте, которая обогнала своё время — и при этом всё равно провалилась. Как вы уже поняли — речь пойдет об Intel i740. Каким был первый GPU от Intel, на что он был способен и в чём заключается его главная тайна — читайте в сегодняшней статье!

I've been fighting my implementation of #OpenGL recursive stenciling for 2D CSG operations for my #McCLIM #Wayland OpenGL backend. I think I finally have it at decent place for the clipping drawing tests but I feel like I'm still missing something in either OpenGL or my recursion that would make it "easier" or "cleaner" code-wise.
Concave polygons are still a TODO and I'm not sure if I'm going to go stenciling or ear-cut tessellation route.

A-EON Technology: Expressions of interest in OpenGL ES V4 possible
As A-EON Technology announces on its website (PDF file), customers who are firmly committed to pre-ordering Version 4 of the OpenGL ES library for AmigaOS 4 at a price of 35 British pounds (approximately 41 euros) can contact the company via e-mail.

IRL things are making regular Friday streaming more difficult lately. So I'm streaming #McCLIM things today at 10:30am CDT/ 15:30 UTC (when this toot is about 50 min old)
https://www.twitch.tv/endparen
Today I'll be focused on fixing some drawing test problems that seem related to my stencil clip masks in #OpenGL

It's been a while since I had time (and quiet) to stream. Today is a new chance. I plan on streaming more #McCLIM #SDL or #OpenGL things in a little under an hour from this posting at 10am CDT / 15:00 UTC. Hopefully I be able to again this Friday.

IME input text is working well, in my view, with SDL2. I'll demo its current state. Next I want to reacquaint with my #Wayland branch and go from there.

Me he comprado el #RollerCoasterTycoon2 (no sé muy bien para que pagar por ello a estas alturas) en #Steam por estar en el descuento más alto disponible y sin #DRM. Para usar con #OpenRCT2.
He tenido que modificar la aplicación para usar Zink. Para poder tener #MangoHUD. No es necesario en absoluto. Pero a mí me gusta tenerlo. No sé la razón, pero con #OpenGL no me funciona MangoHUD.
Si me pico, y alguien se anima, se podría probar las partidas en línea. No sé. Lo dejo caer.

🧵 … actually #Pipewire not working has resulted in a desaster for me.
So, #Lightworks has stopped working because devs introduced an #OpenGL threading error long time ago.
Now there's one video project I have to redo in #DaVinci #Resolve if it ever should get finished.
However, Resolve cannot use #Jack, unlike Lightworks, so I can't use Resolve either.
The only thing that works here is Ardour, Mixbus and Carla.
The work I need to do has stopped. Because it is a Unix work station, like a train station.
My wife says I should stop worrying and buy a Mac.
I mean… all of this worked perfectly well on my #UbuntuStudio #Linux until a) LWKS got screded by devs and b) Pipewire got screwed.
So this is how I spent my Sunday morning.
Now will continue doing voice recordings. On a MacBook Pro 2017.
Madly.

What I'd like to know is, is there a pre-existing tool to turn THIS into something more like THAT?
Not necessarily with the names, but just without the superfluous variables everywhere.
I did it by hand here, and this is one of the shorter, simpler shaders in ACNH. The interesting ones are much bigger.

I've published a new nCine development update, covering the work completed between late 2025 and the first half of 2026.
Highlights include the first public look at GrAIL, a work-in-progress Render Hardware Interface, OpenGL sprite batching improvements with instancing, Windows filesystem optimizations, and many additions to nCTL.

I finished my experiment of porting GPUs to Emacs.
The GPU backend shares a neutral drawing policy across Metal (macOS) and OpenGL (Linux); two drivers, one architecture.
Performance charts (absolute fps, cairo vs GPU):
1616x912 frame: GPU ahead on full redraws (1.19x), at parity on page scrolls
4K frame: GPU pulls ahead on motion (typing 7.4x, image scroll 11.5x)
macOS M1 Pro: vsync on saves 35% CPU during scroll without losing responsiveness.
However, for smaller resolutions the CPU wins.
This version makes sense if you want animations, transitions, or to play GIFs or videos.

Hi folks! ✌️
Here's an update of "Dima wants crisps 🍟" 👇
https://fediverse.tv/w/ei1PuN1aQVZULqNc11UXta 🎬
I've made a view from the first person, have move the background of the game to the back, so it doesn't touches in-game objects, such as grounds anymore, have put a magic stuff to the player's hand 🧙♂️, and now the game use Tiled (https://www.mapeditor.org/) for a maps' creation.
Have a good day! 😜✌️

In the last post I introduced the "dual complement" idea for polyhedral graphs. I'm not sure if it has any mathematical significance, but I've made a fun discovery: the dual complement of a spanning tree is another spanning tree.
This result is rather intuitive and I don't have a rigorous proof for it yet, but here are the main supporting ideas. First, a spanning tree over v1 vertices has v1 - 1 edges. We can then show, using basic duality relations and Euler's polyhedral formula, that the dual complement has v2 - 1 edges that connect all of its v2 vertices. The complement doesn't have any cycles, since those would "capture" parts of the original graph, which we know is a single component.
The original polyhedron here is a {3,5+}_2,1 geodesic, so the dual is a Goldberg polyhedron.
No AI, no apps, just my original Python + OpenGL code.

Back in the day, I made a couple of demos where a Hamiltonian path is carved out on a polyhedron. Looking back, I started to wonder about the shape left around the path, and what it means in terms of graph theory. I call this shape the "dual complement" of the path.
The dual of a polyhedron is essentially the result of turning faces into vertices and vice versa. This is shown in the first clip with a snub dodecahedron and its dual, the pentagonal hexecontahedron; to keep the view cleaner, I'm only showing the edges of one at a time.
The duality transformation also affects the edges, but their number remains the same, and there's a 1:1 mapping between the original and dual edges. Each dual edge "cuts through" the original. To make the dual complement of a path, I remove the dual counterpart of each edge in the path, leaving only the stuff on the sides. It's like driving a snow plough along the path, leaving walls of snow on the sides.
For the final view, I combine original Hamiltonian paths with their dual complements.

And another one new! 📰
I've rename "Dima stand 🧍♂️" on "Dima wants crisps 🍟".
And now this means that Dima now hasn't a plan to stands only 🙂. He also want now to walk, jump, and do more actions! 😎
