Yay! Last-minute success! (only for left-to-right rendering, though)
It appears like I have the scaling working correctly and SDF fonts are rendering as expected. It's even working pretty nicely with the text sizing demo! It looks like I still have a bug with the text bounding box but, visually things are looking much better.
Hey #OpenGL and #graphics people, are there any graphics profiling/instrumentation/frame debugger solutions which work with OpenGL on modern non-Windows systems? Something à la #RenderDoc but that works on #Wayland or Apple Silicon Macs. To do frame debugging right now I have to log out of my Wayland session on my #Linux desktop and log in to #X11, which is uber-broken on my mixed DPI fractional scaling multi monitor setup... #programming #graphicsprogramming #macdev
Trying to get started building a desktop application with a #3D viewport using #Vulkan and #Rust on #Linux.
What. A. Frustrating. Mess.
Fast moving (and breaking) APIs. Outdated examples. Missing features (looking at you, #HiDPI support).
I guess I'm coming back later.
Currently, the most stable approach seems to be #GTK4's GLArea and plain old #OpenGL.

I've begun my profile on Shadertoy as Nom, my first one is here <<https://www.shadertoy.com/view/WcKSzd >> There was a time when I had no idea how to plot the Mandelbrot set so it seems appropriate to start with it. #shadertoy #OpenGL #shaders #nomxd #Tech-talk
@slashdot The ports to #GNU (#Linux is a kernel, not an OS) were done using #OpenGL and the port was made by a different studio than the one which originally developed the games.
Different code, different runtime API, different optimization effort.
Proton runs programs without modification.
If games were written with #Vulkan instead of with #Direct3D, the difference would be even wider.
@grumpygamer generally like having multiple options to be able to check and help with graphics drivers bugs on Linux. Was also surprised that #OpenGL was seemingly faster than #Vulkan with @play0ad on my Lenovo T14s AMD gen3 laptop (only checked briefly though). I'd mostly be concerned about cross platform compatibility, but I guess Vulkan has you covered there. And it's also a little less of a concern for me since #Wine / #Proton and #DXVK have made such a tremendous progress in the last years.

Went to go remove any #microsoft games from my #Steam wishlist, only to realize I don't have a single one on there. No #activison, no #bethesda, no #blizzard. Turns out I haven't really been microsoft's main target for a while. I don't use #Windows. Never used #Bing. Don't write programs with #DirectX, I use Vulkan and #OpenGL and #SDL. Don't use #OneDrive. Never used #Skype. Don't use an #Xbox #controller on my PC, I use an 8bitdo controller. Don't use #Azure. I am disconnected from them.
Testing the Gosper curve in my variable iteration halftoning setup. So far I've only used the Hilbert curve this way, and things get a bit coarser with the Gosper, so it was harder to find images that make nice results. So here we are with the old Venus again.
The number of points multiplies by 4 for Hilbert and 7 for Gosper on each step, so the latter has to get by with fewer iterations for a sensible resolution. Here we have 6 iterations for 6 grey levels.
text rendering finally works!!
i will add support for ttf later, but for now its implemented via a texture atlas

haven't really used this account much but heres a game engine i've been working on for around a month using opengl and C
Is it me or are all four of these doing basically the same thing?
Free Linux driver for Nvidia GPU will support OpenGL via Vulkan in future
With newer GeForce GPUs, Linux distributions will use a driver for OpenGL applications that hands over the actual work to a Vulkan driver.
Freier Linux-Treiber für Nvidia-GPU unterstützt OpenGL zukünftig via Vulkan
Bei neueren GeForce-GPUs werden Linux-Distributionen für OpenGL-Anwendungen einen Treiber nutzen, der die eigentliche Arbeit einem Vulkan-Treiber übergibt.
AMD Radeon GPU Analyzer (RGA) is our performance analysis tool for #DirectX, #Vulkan, SPIR-V, #OpenGL, & #OpenCL.
As well as updates for AMD RDNA 4, there's enhancements to the ISA view UI, using the same updated UI as RGP

Someone who has more technical knowledge of #ComputerGraphics and its associated math, how exactly does RGBM encoding work? I understand the steps of taking the maximum and then divide it across, but what exactly does that do graphically?
I consulted a number of old blogs but it doesn't seem to 'click' yet.
What I'd like to do is render these pieces in the correct orientation, including the grass bits on top, but somehow make the actual grass texture always appear such that it faces right-side-up, like it does on the unrotated flat ground.
How would I do this?
