i think my software rasteriser is broken

Some fun with shader-based debug drawing: here I'm drawing an arrow for each path taken in the path tracer, starting with the pixel under the mouse cursor.

It's finally here! I'm pleased to share GP-Direct 2025, the latest edition of the graphics programming discord showcase! No engine? No problem. We wrote our own! Thank you to all the talented people who participated! youtu.be/e9qK6EtqB-Q?... #indiegamedev #graphicsprogramming

I'm thrilled to announce that GP-Direct, the Internet's most exciting graphics showcase, is back and has received all clips for 2025! We will soon be releasing our final video just as soon as we finish editing. Here's last years video! #indiegamedev #graphics www.youtube.com/watch?v=E07I...

been working on the scene graph recently #vulkan

Hola again graphics peeps! 😊 I found myself with enough bits and pieces related to text rendering to warrant a write-up. So here it is! 😱 osor.io/text Spiced up with direct vector rendering, sub-pixel anti-aliasing, run-time atlas packing, temporal accumulation, and more! I hope you enjoy it! 🧡

Decided to check out how water is rendered in Counter-Strike 2. Given how interactive water in CS2 is, I expected to see some cellular fluid simulation, but turns out they just use a low-resolution off-screen buffer with flat 2D decals used for various aspects of water. Reminds me of HL2 water :)

shader hot-reloading in #vulkan was easier than i expected hehe

Hey all, Have you ever been confused or frustrated by baking materials in blender? Well I wrote a guide to to help you out. Please check it out as well as the other blogs on graphics-programming.org #blender3d #tutorial #indiegamedev graphics-programming.org/blog/blender...

Upsampling via Multisampling filmicworlds.com/blog/upsampl...

found this really cool series. i wanna study low-level stuff at some point... like graphics drivers.. make my own operating system... build a fpga gpu.. really cool stuff!!! youtu.be/B8xHWwCuxKA?...

im gonna cancel a lot of the "engine work" i was planning on doing in my #vulkan engine to make it presentable asap so i can work on other stuff to apply for internships in september. like timeline semaphore and slang is cool, but before and after is gonna be the same from the outside.

ended up choosing the virtual geometry one. gonna have to learn a lot but looking forward to start implementing it this summer!

In today's new blog post, I try to provide some intuition and clear up some misconceptions about early Z cull behavior on desktop GPUs. Have a read if that interests you! therealmjp.github.io/posts/to-ear...

working parsing #vulkan spir-v to build my pipelines easier 😋 gonna keep it super simple. after this i probably wanna cleanup everything again and maybe add some new visual stuff 👀.. or improve perf. cause i made it worse accidentally 💀

changed my #vulkan engine ui to use #imgui docking need to add a scene tree and better settings but it's low priority (im procrastinating)

im refactoring how rendering is done in my #vulkan engine to re-add transparency. ill try to finish this weekend and then gonna add spirv reflection to simplify creating pipelines :) and remove all that ugly code

it's been kinda hard working on the projects due to lack of motivation ... :(

raytracer voxels raymarcher virtual geometry need to choose one for my 3rd year project 🤔🤔

got a new charger 😋

i was so close to locking in but i forgot my charger at home so i physically can't 💀💀

I'll get back to my gamedev & graphics programming eventually

need to lock in.. i haven't worked that much this last couple weeks. wip is compacting the indirect draw calls

photogrammetry looks cool

Impromptu stream! In 10 minutes we will work on improved materials and shadows in niagara :) youtube.com/live/iZTUjRn...

im rlly close to indirect draw working... refactoring to have one big index buffer broke my shi but.. it was sort of working.. need to fix that n then change how I upload stuff .. im gonna keep it simple. big buffers but only one gltf at a time and changing it rebuilds so no fragmentation

i fixed it!!! and i moved the material data to a buffer and it worked first try! (normally i have to crash out 3-4 business days before i can fix it)

my renderer is cooked 💀💀 wip draw indirect in #vulkan

i got bindless working sort of now moving towards indirect draw :) ... first gotta sort out the global uniforms ... maybe i can get there in a week? naive impl. and then fix bloom shadows ssao.. watch some talk about boneless and improve?? idk.. next goal is indirect draw similar to vkguide

i gave up

GPU Zen 3 is finally out! I had the honor to contribute to this edition by writing chapter 17, "Simple Automatic Resource Synchronization Method for Vulkan". Thanks to all the editors and @wolfgangfengel.bsky.social for keeping the tradition of these books around :-) www.amazon.com/dp/B0DNXNM14K

im close to going bindless in my #vulkan renderer 🤏🤏 first impl is gonna be pretty bad but at least it's bindless. probably gonna spend a couple days improving it n fixing the stuff it broke

i can't get frustum culling to work... might crash out ngl

im done with ssao for now.. tbh i need to fix performance and it looks like ass 💀💀 but im gonna change the renderer soon so icba rn. #vulkan #graphicsprogramming

still working on ssao, gonna get the blurring step working..

"hey guys just moved to bluesky"

hiya i just joined, will be using this account to document progress in learning graphics programming, game development, and other personal projects! :)
