I'll stream #McCLIM #OpenGL and #CommonLisp things today, 12/12, at 12pm CST/ 18:00 UTC
I didn't think I'd have time today due to IRL things but I suddenly have some time. We'll start by cleaning up / archiving a failed index buffer attempt and then will find the next issue that needs tackling.
I was looking for a way to display mouse-over context information in a 3D scene, and the solution I came up with is to encode the ID of each object into colors, and render that to an off-screen framebuffer. Then, I can simply look up the pixel at the current cursor coordinates and get the ID!
It feels like a cheeky hack, but honestly I can't think of any other practical way for this - does anyone know how games and such do this?
#OpenGL hatte nen Bug. Einfach so. Hab zum Glück Timeshift installiert und konnte zu nem stabilen Snapshot zurückspringen. Ohne hätte ich #Linux neu aufsetzen müssen. Es bleibt also dabei: Linux ist nicht ausgereift und wird es auch nie sein. Ist halt das Konzept. Linuxanwender sind Betatester auf ewig. Deshalb wird es auch für immer das superstabile #Windows geben, neben #MacOS. Linux ist und bleibt Spielkram und ist für einen produktiven Einsatz nicht zu gebrauchen. Egal, dafür ist's for free.

I spent the evening preparing utilities to deal with meshes using modern #OpenGL DSA (Direct State Access) functions in C. There is not a lot of clear information about it, so I used Grok as a partner to study the topic (just for research/analysis, I wrote the code myself). Very productive. Learned a lot, ended up with a very clear abstraction for VBO/IBO/VAO and support for several vertex attribute combinations (position + color and/or texture coordinates).
#KodeLife #realtime #GPU #shader editor update out today!
We've done more work on getting our stock projects to play nice with more of those lovely #OpenGL ES 3 drivers, added some first-class menu and keyboard shortcut support for modern #iOS systems, plus of course the usual fix-ups...
Happy Koding!
Sorry again for late notice but RL has been hectic.
I'm going to try streaming #McCLIM and #OpenGL things today 12/5 at 12pm CST / 18:00 UTC https://twitch.tv/endparen
Recently I was able to get SDF fonts working via GPU VBOs. However this broke multiple window fonts. Today we try to fix it.
ICYMI: Mesa 25.2.8 and 25.3.1 open source graphics drivers released for Linux
#AMD #Intel #LegionGoS #Linux #LinuxGaming #Mesa #NVIDIA #OpenGL #OpenSource #PCGaming #Radeon #SteamDeck #SteamFrame #SteamMachine #SteamOS #Vulkan
Finally I have worked through my subtle OpenGL bugs and have working SDF font rendering via pre-loaded VBOs with precomputed UV and geometry data.
There is still a lag with pointer highlighting but the stream test stays snappy and doesn't get progressively slower with each event displayed.

Основы AGSL для android разработчика
В последние годы интерфейсы приложений становятся все более интерактивными. Простого эффекта нажатия на кнопку уже недостаточно - пользователи ждут живых анимаций и визуальной глубины. Но создание таких эффектов традиционно требовало от разработчиков значительных усилий. Представь: тебе нужно «поколдовать» над пикселями прямо в UI - добавить живой градиент, искажение картинки под пальцем, стеклянный блеск карточке и тому подобные эффекты. Раньше для этого приходилось прибегать к «тяжеловесам» таким как OpenGL/Vulkan, либо мучить CPU постобработкой битмапов. AGSL (Android Graphics Shading Language) решает это элегантнее: это язык фрагментных шейдеров, встроенный в сам графический стек Android, так что эффекты применяются прямо на уровне отрисовки интерфейса.

TIL about the GL_ARB_debug_output which provides a user callback to have all #OpenGL debug/error messages be signaled without having to call glGetError for every single OpenGL call.
A bit chatty because errors tend to happen at every single frame, but rate limiting identical messages is easy with a hash table. Oh and it's core since OpenGL 4.3.

I plan on streaming #McCLIM things today in appox. 4 hours at 12pm CST / 18:00 UTC. I failed in my plan to give extra notice yesterday. (sorry @screwlisp ) I'll try to send another reminder 1 hr before.
Today might be more tedious work debugging #OpenGL vertex buffers and my attempt to transition to them for font atlases.
