i find it strange that the SDL gpu api has no

Present

Present

Present

Present function of any kind
no clue when it actually swaps the buffers, it can't be after submitting the command buffer since you should be able to submit multiple

Lyris the Kitori•10/7/24, 11:40 AM

acquiring a swapchain image takes a command buffer iirc
it presents when you submit the command buffer you pass there

AquaOP•10/7/24, 11:41 AM

ahh that makes sense

AquaOP•10/7/24, 11:51 AM

after using the shadercross api for all of about 5 minutes i now 100% get the purpose of the pr

AquaOP•10/7/24, 11:51 AM

the type safety is nonexistent

AAqua beyley pr spotted

TechPizza•10/7/24, 1:35 PM

surprised it wasn't an enum in the first place

Essial•10/7/24, 2:25 PM

it's shocking how much easier it is to write a cross platform gtk gui app in C# than C/C++ as far as dependencies go

Essial•10/7/24, 2:44 PM

i spent 4 hours on sunday trying to get a stable hello world building in windows/linux/mac and literally couldn't. but with c# it's just a nuget package

AAqua i find it strange that the SDL gpu api has no `Present` function of any kind no ...

AquaOP•10/7/24, 3:52 PM

trongle

AquaOP•10/7/24, 3:54 PM

only works under vulkan, d3d11 and d3d12 do not work
no clue why

AquaOP•10/7/24, 3:56 PM

my overall opinion of the api: cool but meh. the namespacing is atrocious and it's missing some things i would expect a gpu api to have (i know it has just been released though so hopefully that can be changed). shader compilation is somewhat poor as well. but it works decently (on vulkan anyway...) and is relatively clean

Rahkiin•10/7/24, 4:54 PM

Doesnt sound very convincing. Maybe ill use it as a second api

Perksey•10/7/24, 4:55 PM

just one opinion though

TechnicJelle•10/7/24, 4:55 PM

Oh yeahh

TechnicJelle•10/7/24, 4:56 PM

Didn't they do their function naming "from small to big" instead of from "big to small"?

TechnicJelle•10/7/24, 4:56 PM

SDL_GPU_thing_doit
vs
SDL_do_thing_on_GPU

Rahkiin•10/7/24, 4:57 PM

That is the new sdl3 naming

Rahkiin•10/7/24, 4:57 PM

Sdl_getatomicint

TechnicJelle•10/7/24, 4:58 PM

Mhm

TechnicJelle•10/7/24, 4:58 PM

I do admit that is one gripe I have with it

PPerksey just one opinion though

Rahkiin•10/7/24, 4:58 PM

Aye so i can form my own by using it is as a second api instead of nuking my first one

fair point tho

Rahkiin•10/7/24, 4:58 PM

No idea why they went with that. Easpecially now sdl has grown

Rahkiin•10/7/24, 4:59 PM

Sdl_atomic_getint and sdl_gpu_getswapchain would have been better imo

Rahkiin•10/7/24, 4:59 PM

But if you use the original c then the headers are acting as a kind of namespaces

RRahkiin Doesnt sound very convincing. Maybe ill use it as a second api

AquaOP•10/7/24, 7:01 PM

yeah as perksey said don't base yours on my opinion lol

AquaOP•10/7/24, 7:01 PM

i have generally strong opinions about most thing and as a british person love to complain about everything

AquaOP•10/7/24, 7:02 PM

use it for yourself, it's genuinely decent and would serve well as a primary api, my negative points are really pretty minor in the scheme of things

AquaOP•10/7/24, 7:03 PM

aside from d3d11 and d3d12 not working, not sure what that's about, not sure if that's an issue on my side of some kind (incorrect parameter, bad compilation etc) or a genuine bug in sdl_gpu

AquaOP•10/7/24, 7:04 PM

i would suspect the former as i don't see why it would be a bug in sdl gpu, although i can't work out what the problem actually is

Lyris the Kitori•10/7/24, 7:04 PM

does it just not render or crash

AquaOP•10/7/24, 7:05 PM

d3d11 complains about an incorrect parameter (although i checked the raw d3d code and everything seems correct), d3d12 plain crashes

Lyris the Kitori•10/7/24, 7:05 PM

strange

AquaOP•10/7/24, 7:06 PM

all to do with the pipeline creation, in d3d11 it's the input layout and in d3d12 it's the root signature creation, i suspect the shaders are bad in some way

AquaOP•10/7/24, 7:06 PM

currently compiling direct from hlsl, might try spir-v instead

Lyris the Kitori•10/7/24, 7:06 PM

ah i havent tried that, could be bad shaders in that case

TechnicJelle•10/7/24, 7:07 PM

It also still supports OpenGL, right?

AquaOP•10/7/24, 7:07 PM

yea the dx compiler isn't the best, it assumes a

main

main

entry point and doesn't let you change it, i can kinda get it cause dxc uses wide strings which is a pain, but kinda annoying. hope they can fix that someday

TTechnicJelle It also still supports OpenGL, right?

AquaOP•10/7/24, 7:07 PM

doesn't seem to, no

AquaOP•10/7/24, 7:07 PM

imo, good. opengl tends to bring down apis like this nowadays

AquaOP•10/7/24, 7:08 PM

the biggest pain point in GRABS is the opengl backend as well

AAqua imo, good. opengl tends to bring down apis like this nowadays

TechnicJelle•10/7/24, 7:08 PM

Fair

TechnicJelle•10/7/24, 7:08 PM

Bit sad for older hardware though

Lyris the Kitori•10/7/24, 7:08 PM

anything which supports a new enough GL to support the API's features also supported D3D11/12 or VK

Lyris the Kitori•10/7/24, 7:08 PM

it was seen as a losing battle to support GL

TechnicJelle•10/7/24, 7:09 PM

I have a friend with a laptop that's not too old (8th gen Intel iirc?) that doesn't support Vulkan rendering
Only OpenGL..

AquaOP•10/7/24, 7:09 PM

yeah, there's generally no reason to support opengl anymore unless you target like 3.3 which means you miss out on a lot of features (assuming you don't target extensions, but even then)

AAqua yea the dx compiler isn't the best, it assumes a `main` entry point and doesn't ...

Lyris the Kitori•10/7/24, 7:09 PM

yeah i saw that
i use glsl through glslc in my code

AquaOP•10/7/24, 7:09 PM

the only reason i support it is because i'm literally too lazy to learn vulkan

LLyris the Kitori yeah i saw that i use glsl through glslc in my code

AquaOP•10/7/24, 7:10 PM

yeah fair enough, think i will try the same

i find it strange that the SDL gpu api has no `Present` function of any kind no clue when it actuall
