@dieter_debaets @maxliani Oh I just used __debugbreak() (one day c++ will have std::breakpoint).

@maxliani also VK_DBG_LAYER_ACTION_BREAK can do wonders (if you have a debugger attached ofc)

I don’t know why this never came to me before… but printing the callstack from within the Vulkan validation layer callback makes it way easier to debug what’s happening. That enables automated troubleshooting and fixes for a whole class of issues. Neat!

@TopoWeaverIO I do notice quite a bit of pop in at the edges of the forests

@TopoWeaverIO That’s awesome, I wanna make something similar but using Vulkan. Very fast movement thru a huge world, emphasis on physics based gameplay. How did you make your world, are the trees instanced?

Readded the shadows to the new rendering system. Still a lot of optimizations required.. #webgpu #indiedev #indigame

@ptrToLiam Yes please

Decided to try writing a blog post and realized it's been quite a while since I've written any sizable text.

@the_geeko1 @TsukiHyouka I have a script to unzip them after I clone

@TsukiHyouka when it comes to games .. assets are linked to your code and you want to at maintain some version management. that's why stuff like git-lfs and perforce are there for.

You shouldn't upload binary nor assets to github, your repo should hold just the code and the assets could be imported independently.

24 gbs of VRAM is a LOT of VRAM. But it's not infinite.

@Dispatch_Graph It's gonna need relevant test scenes that make the most of the rendering approach

Now that I have the M5 MBP my goal is to just fuckin max out my GPU. GPU driven everything. Build/cull TLAS on GPU. Cull instance/meshlet/triangle on GPU. Run ML model to approximate AO. DDGI. I want to see how far I can push it

Just got to Vulcanus in factorio…so hype

@walaber How do you get such beautiful assets like that knob? Do you make them?

I use springs for everything and no one can stop me 😅

and prioritizing making yourself uncomfortable probably. being uncomfortable is a good sign but it doesn't inherently mean you're succeeding or growing.

the answer is to do everything

whether to spend time on these personal endeavours vs open source. i wrote a compiler at one point during college but i may have learned more by using that time to get involved with gcc/mesa. you have to learn a lot of cruft but your work is held to a much higher standard which

Long way to go but it’s fun and something that I think should exist

* animation * some kinda physics * chunked world representation with LOD * GPU culling * PBR slop * RTX * god rays 😍 I want millimeters of geometric detail up close. But I need assets! I could try generating terrain, I am also learning how to use blender to make ugly boxes.

Things that my graphical program can now do: * hardware capability detection * feature fallback resolution * settings override via CLI flags * packaged builds for steam deck * bindless rendering * slang shaders * model loading on a background thread * imgui * nice camera move

@ptrToLiam Yea I’ll have to triple check that I don’t have validation layers on somehow, maybe vkconfig was pointed at the wrong SDK. I obviously want this to be very fast!

@eddieprograms That is strange. I wonder if it could be wayland I/O, or maybe just general GLFW platform-layer setup? I don't use libwayland, so I can't say for sure how long it *should* take. I'm also not particularly familiar with GLFW's internals.

Kind of surprising how long VkDevice and GLFW window creation take! And not sure how to get around it other than maintaining some kind of background runtime that caches these

@ptrToLiam Wow I wonder why mine takes 400ms then

@eddieprograms It varies a little from run to run (best ~140, worst ~200, typical 155ms) and I can probably drop one or two socket writes during startup to shave a little more time off that. It's good enough for me for now, and I hot-reload the shader on change so I don't relaunch too often.
