#

don't tell me this is phobos

tropic vigil Aug 6, 2023, 8:47 AM

#

Hmm

#

Ill take a look

tropic vigil Aug 6, 2023, 9:10 AM

#

are these used in the shader

#

shader reflection is running for rt pipelines too yeah

#

and theres no special handling for them there

dawn wave Aug 6, 2023, 11:23 AM

#

Ahhh that might br why

#

Let me try using it in the shader

#

 ERROR phobos::core::debug             > [VALIDATION]: VUID-vkCmdPushConstants-offset-01795 (666667206): Validation Error: [ VUID-vkCmdPushConstants-offset-01795 ] Object 0: handle = 0x201b6126490, type = VK_OBJECT_TYPE_COMMAND_BUFFER; | MessageID = 0x27bc88c6 | vkCmdPushConstants(): VK_SHADER_STAGE_RAYGEN_BIT_KHR, VkPushConstantRange in VkPipelineLayout 0x7ddd740000000051[] overlapping offset = 128 and size = 8, do not contain VK_SHADER_STAGE_RAYGEN_BIT_KHR.

#

hnnn

#

i have no clue why this bug is happening

#

hm
Mat4
Mat4
u32

#

that shouldn't be an issue...?

#

I think phobos borked

#

layout(push_constant) uniform PushConstants {
    mat4 view;
    mat4 projection;
    uint frame_id;
} pc;

if (pc.frame_id > 1) {
        vec3 old_color = imageLoad(old_image, ivec2(gl_LaunchIDEXT.xy)).rgb;
        // Caulcate contribution
        float a = 1.0f / float(pc.frame_id);
        // Mix the old and new colors together
        vec3 final_color = mix(old_color, payload.incoming_light, a);

        imageStore(rt_out, ivec2(gl_LaunchIDEXT.xy), vec4(final_color, 1.0));
        imageStore(old_image, ivec2(gl_LaunchIDEXT.xy), vec4(final_color, 1.0));
    } else {
        // First frame, do not worry about accumulation
        imageStore(old_image, ivec2(gl_LaunchIDEXT.xy), vec4(payload.incoming_light, 1.0));
        imageStore(rt_out, ivec2(gl_LaunchIDEXT.xy), vec4(payload.incoming_light, 1.0));
    }

#

I mean it should be fine?

#

yet why

#

it seems like it can't detect the uint push constant and keeps spamming out that one message over and over

tropic vigil Aug 6, 2023, 11:52 AM

#

does it still work even with that message

dawn wave Aug 6, 2023, 11:52 AM

#

no it seems like the shader defaults frame_id to zero. It does run but frame_id is set to zero

tropic vigil Aug 6, 2023, 11:53 AM

#

ive gotten that message before too and i dont really know where it comes from but it always worked fine for me

#

hmm

#

ill have to look into it then

#

make sure each shader stage declares the same push constant block

#

even if some variables are unused in that stage

dawn wave Aug 6, 2023, 11:53 AM

#

oh each shader stage

#

wait really?

#

so like my rchit, rmiss

#

also should declare the same block?

tropic vigil Aug 6, 2023, 11:54 AM

#

Ye

dawn wave Aug 6, 2023, 11:54 AM

#

bleakekw

devout mesa Aug 6, 2023, 11:54 AM

#

wat why

dawn wave Aug 6, 2023, 11:54 AM

#

iirc your examples don't do that

#

and it runs fine

tropic vigil Aug 6, 2023, 11:55 AM

#

do they not

#

weird

#

i think that could fix this error though

dawn wave Aug 6, 2023, 11:56 AM

#

pls fix the error message

#

i could look into as well

#

it shouldn't be that bad

#

seems like you might be forgetting to change the layout size

#

it's weird though

#

as keeping two mat4s runs perfectly fine

tropic vigil Aug 6, 2023, 11:57 AM

#

its in the shader reflection find_push_constants i assume

#

something is going wrong there

dawn wave Aug 6, 2023, 11:58 AM

#

iirc this wouldn't be a shader problem however

#

ah fuck

#

hmmm

#

setting the push constant in each shader

#

does not remove the error

#

some good news however

tropic vigil Aug 6, 2023, 12:00 PM

#

check if the pipeline layout is what you expect it to be

dawn wave Aug 6, 2023, 12:00 PM

#

it seems like frame_id is working and it's incrementing up

tropic vigil Aug 6, 2023, 12:00 PM

#

in the debugger

dawn wave Aug 6, 2023, 12:00 PM

#

but the error message is still being thrown

#

okok will do

#

OpMemberDecorate %100 0 ColMajor
OpMemberDecorate %100 0 Offset 0
OpMemberDecorate %100 0 MatrixStride 16
OpMemberDecorate %100 1 ColMajor
OpMemberDecorate %100 1 Offset 64
OpMemberDecorate %100 1 MatrixStride 16
OpMemberDecorate %100 2 Offset 128

#

This seems fine?

#

uhh

#

i can't seem to find the pipeline layout

#

@tropic vigil It says 3 push constants were made

tropic vigil Aug 6, 2023, 12:15 PM

#

can you show the struct with pipeline layout info

#

uh hold on

#

#[derive(Debug, Clone, Default)]
pub struct PipelineLayoutCreateInfo {
    /// Pipeline layout flags
    pub flags: vk::PipelineLayoutCreateFlags,
    /// Descriptor set layouts for this pipeline layout.
    pub set_layouts: Vec<DescriptorSetLayoutCreateInfo>,
    /// Push constant ranges used in this pipeline
    pub push_constants: Vec<PushConstantRange>,
    /// Whether this pipeline layout is persistent, e.g. whether it should be kept alive forever
    /// by the cache. Use this with caution, as it can cause large memory spikes for frequently changing
    /// pipeline layouts.
    pub persistent: bool,
}

#

This one

#

The push_constants field

dawn wave Aug 6, 2023, 12:15 PM

#

ohh okok

tropic vigil Aug 6, 2023, 12:16 PM

#

You can set a breakpoint on line 349 in shader_reflection.rs

dawn wave Aug 6, 2023, 12:17 PM

#

how tf do i access it bleakekw

#

i can't find this file

#

uhh

tropic vigil Aug 6, 2023, 12:19 PM

#

pipeline/shader_reflection.rs

#

All the way at the bottom it returns the completed layout

dawn wave Aug 6, 2023, 12:20 PM

#

self = {*mut phobos::pipeline::pipeline_layout::PushConstantRange} 0x000002317ec47bf0 {stage_flags={__0=256}, offset=0, size=132}
 stage_flags = {ash::vk::bitflags::ShaderStageFlags} {__0=256}
 offset = {u32} 0
 size = {u32} 132

#

bleakekw isn't that the correct size?

tropic vigil Aug 6, 2023, 12:22 PM

#

hmmm

tropic vigil Aug 6, 2023, 12:22 PM

#

dawn wave ```glsl layout(push_constant) uniform PushConstants { mat4 view; mat4 pr...

this is your pc block right

dawn wave Aug 6, 2023, 12:22 PM

#

yeah

tropic vigil Aug 6, 2023, 12:22 PM

#

looks about right then

dawn wave Aug 6, 2023, 12:22 PM

#

then ig my validation layer is simply built different bleakekw

tropic vigil Aug 6, 2023, 12:22 PM

#

what type is frame_id

dawn wave Aug 6, 2023, 12:22 PM

#

u32

tropic vigil Aug 6, 2023, 12:23 PM

#

thonk

dawn wave Aug 6, 2023, 12:23 PM

#

🤔

tropic vigil Aug 6, 2023, 12:23 PM

#

then what is it saying about offset 128 size 8

#

how size 8

#

that makes no sense

dawn wave Aug 6, 2023, 12:24 PM

#

oh yeah

#

uint is 4

#

tf

#

🤔

tropic vigil Aug 6, 2023, 12:24 PM

#

do you have push constants in any other shader

dawn wave Aug 6, 2023, 12:24 PM

#

no i don't

tropic vigil Aug 6, 2023, 12:24 PM

#

hmm

dawn wave Aug 6, 2023, 12:24 PM

#

let me try to update vulkan

tropic vigil Aug 6, 2023, 12:24 PM

#

so the pipeline layout looks correct

dawn wave Aug 6, 2023, 12:25 PM

#

brb

#

will update vulkan

#

maybe that fixes it

tropic vigil Aug 6, 2023, 12:26 PM

#

One more thing you can try is lookign at command_buffer/incomplete.rs line 568 and check if the byte buffer data has 4 elements

dawn wave Aug 6, 2023, 12:27 PM

#

so uh

#

news

#

the issue dissapeared

#

huh

#

less noise

#

@tropic vigil Idfk what happened but the problem went away bleakekw

#

maybe my shader weren't updating?

tropic vigil Aug 6, 2023, 12:29 PM

#

bleakekw

#

maybe you didnt recompile it yea

dawn wave Aug 6, 2023, 12:29 PM

#

okok now we can make progress

#

what to do next

#

i should probably jitter the pixel

devout mesa Aug 6, 2023, 12:30 PM

#

contact hardening

dawn wave Aug 6, 2023, 12:30 PM

#

wtf

devout mesa Aug 6, 2023, 12:30 PM

#

and jitter yes

dawn wave Aug 6, 2023, 12:30 PM

#

what is contact hardening

devout mesa Aug 6, 2023, 12:30 PM

#

go outside

#

see some shadows

#

that's contact hardening

dawn wave Aug 6, 2023, 12:30 PM

#

oh soft shadows?

devout mesa Aug 6, 2023, 12:30 PM

#

aka real, true shadows

#

hard shadows at the base, soft shadows far

dawn wave Aug 6, 2023, 12:31 PM

#

OH

#

okok

devout mesa Aug 6, 2023, 12:31 PM

#

#general message

#

it shall look beautiful like this

dawn wave Aug 6, 2023, 12:31 PM

#

hmmm how to contact harden

#

oh i probably should add area lights to do that

#

oh no light sampling

#

oh no

devout mesa Aug 6, 2023, 12:32 PM

#

dawn wave oh i probably should add area lights to do that

no

#

it's very ez

dawn wave Aug 6, 2023, 12:38 PM

#

thonk

#

i'm too dumb

#

bleakekw

devout mesa Aug 6, 2023, 12:49 PM

#

randomize ray target towards the sun by a small amount

dawn wave Aug 6, 2023, 12:49 PM

#

o

#

OH

#

#

contacts: harden

#

pixels: jittered

#

rt: on

devout mesa Aug 6, 2023, 12:54 PM

#

good

dawn wave Aug 6, 2023, 12:54 PM

#

impl rendering equation time

devout mesa Aug 6, 2023, 12:54 PM

#

I will now crush your dreams

dawn wave Aug 6, 2023, 12:54 PM

#

o :(

devout mesa Aug 6, 2023, 12:55 PM

#

any of this isn't physically correct

#

go study light transport theory

dawn wave Aug 6, 2023, 12:55 PM

#

yeah it isn't bleakekw

#

oh no

#

pbrt.org

#

it's time

#

where tf do i start

#

gpu gems

#

or like

#

ahhh

dawn wave Aug 6, 2023, 1:47 PM

#

i should probably rework asset loading however

#

it's really slow

dawn wave Aug 6, 2023, 3:48 PM

#

#

god it looks beautiful

#

I CANT STOP STARING AT IT

dawn wave Aug 7, 2023, 12:29 AM

#

note to self:

#

use image crate to handle images KEKW

#

it's so much easier + faster

tropic vigil Aug 7, 2023, 10:47 AM

#

yes except its performance in debug is really bad

dawn wave Aug 7, 2023, 10:47 AM

#

It’s way faster than my original method bleakekw

#

I was iterating over the entire image with a par_iter to add the alpha channel

tropic vigil Aug 7, 2023, 11:15 AM

#

Bruh lmao

dawn wave Aug 7, 2023, 4:18 PM

#

I have no clue where to start when learning light transport theory bleakekw

#

I have to also learn some more probability mainly monte carlo stuff (i don't understand why pdfs exist)

#

man raw vulkan is hard :(

#

i forgor most things already from learnopengl bleakekw

dawn wave Aug 7, 2023, 6:26 PM

#

this is big
(i should be learning light transport theory lmaooo instead of learning raw vulkan)

#

tropic vigil Aug 8, 2023, 10:47 AM

#

dawn wave man raw vulkan is hard :(

bleakekw why are you doing this

dawn wave Aug 8, 2023, 1:34 PM

#

tropic vigil <:bleakekw:1082598350303539240> why are you doing this

I honestly don’t know KEKW
I think it would be a cool learning resource for my engine and also to understand what the hell phobos is actually doing

#

Also maybe defect

dawn wave Aug 8, 2023, 4:18 PM

#

LVSTRI you got a version of bistro with the exterior + interior?

devout mesa Aug 8, 2023, 4:28 PM

#

yes but I think my drive space is over

#

KEKW

dawn wave Aug 8, 2023, 4:29 PM

#

aw bleakekw I need the scene

#

I can't find an online one which has lights + emissives

#

uhh

#

isn't there any alternatives to bistro?

devout mesa Aug 8, 2023, 4:43 PM

#

just diy in blender

dawn wave Aug 8, 2023, 4:45 PM

#

also it's time to bikeshed how should i store my lights in my scene

#

we got the obvious solution:
Buffer containing vec4 -> r,g,b,intensity

dawn wave Aug 8, 2023, 6:17 PM

#

bro this monte carlo stuff

#

is hurting my head

dawn wave Aug 8, 2023, 7:44 PM

#

forget monte carlo

#

probability density functions

#

so confusing

dawn wave Aug 9, 2023, 9:46 AM

#

i'm gonna dissapoint lvstri

#

instead of studying

#

ill just implement rt in one weekend KEKW

#

i need to see pretty pictures

devout mesa Aug 9, 2023, 9:47 AM

#

they do explain the math

#

so it's fine

dawn wave Aug 9, 2023, 9:47 AM

#

yeahh but it isn't pbrt level

devout mesa Aug 9, 2023, 9:47 AM

#

as long as you read properly frog_police

dawn wave Aug 9, 2023, 9:47 AM

#

heh

#

bold assumption

#

tbfh rt in one weekend is not scary

#

it's the stats i fear

tropic vigil Aug 9, 2023, 11:35 AM

#

did you never take a stats course

dawn wave Aug 9, 2023, 11:35 AM

#

i only got grade 12 stats

tropic vigil Aug 9, 2023, 11:35 AM

#

pdf's arent too complicated conceptually

dawn wave Aug 9, 2023, 11:35 AM

#

so cdfs

#

pdfs i think i got?

tropic vigil Aug 9, 2023, 11:36 AM

#

if you understand what a normal distribution is and how to interpret a bell curve you understand pdfs

dawn wave Aug 9, 2023, 11:36 AM

#

KEKW

#

but the wording is confuzzling

#

i'm too used to having it be explained to me nicely by a hs teacher

tropic vigil Aug 9, 2023, 11:36 AM

#

lmao

dawn wave Aug 9, 2023, 11:37 AM

#

like i search what a pdf is and 3 different definitions come back

#

idk i'm following the pbrt one iirc it was something like a pdf describes the relative probability of given variable(s) x occuring

tropic vigil Aug 9, 2023, 11:39 AM

#

thats not really accurate since your variable is not discrete typically

dawn wave Aug 9, 2023, 11:39 AM

#

yeah if it's continious then iirc it describes a domain within the function

#

can't be a single value well it can I think? but it'll be zero

#

I still don't get the difference between it and a probability distribution function is however as iirc in my stats class P(2<=x<=4) would cover the same thing unless I'm stupid (i am)

dawn wave Aug 9, 2023, 1:28 PM

#

oh i forgot to show this off

#

god dammit i can't find a good scene

dawn wave Aug 9, 2023, 1:54 PM

#

bro

#

infinity mirrors

#

are wack

#

#

stare into the cube long enough and the cube stares back at you

#

#

suzanne

#

feral trellis Aug 9, 2023, 2:08 PM

#

dawn wave yeah if it's continious then iirc it describes a domain within the function

Ok you fucking lost me there bud (explain in gr 11 terms pls)

dawn wave Aug 9, 2023, 2:08 PM

#

me neither

#

:D

#

i vaguely understand what a domain is

#

but i cannot describe it to you

#

but uhh

#

I can give you a reasonable example

#

f(x) => x in real numbers

#

essentially that means [0.0, 5.3] would be in the domain of x

feral trellis Aug 9, 2023, 2:09 PM

#

Oh okok so like the same domain/ranges shit as in gr 11 functions

dawn wave Aug 9, 2023, 2:09 PM

#

sorta?

#

idfk man KEKW

#

domains contain a lot of things

#

all i know is it's usage within vulkan and co. in terms of algos.

feral trellis Aug 9, 2023, 2:12 PM

#

Yea welp I guess I'll have to look more into that before calc and vectors

dawn wave Aug 9, 2023, 2:12 PM

#

it's not covered in grade 12 KEKW

feral trellis Aug 9, 2023, 2:13 PM

#

Oh ok well... before Uni at least!

dawn wave Aug 9, 2023, 2:13 PM

#

just understand what the terminology means in your case the grade 11 definition is probably good

dawn wave Aug 9, 2023, 2:31 PM

#

#

dude this iamge

#

is just so

#

fuckingcool

#

holy shit

dawn wave Aug 9, 2023, 3:34 PM

#

GOOD MORNING (i have yet to sleep)

dawn wave Aug 9, 2023, 11:11 PM

#

Guys

#

I think I understand pdfs

dawn wave Aug 10, 2023, 2:32 AM

#

So ih

#

How would you play a video in a scene?

dawn wave Aug 11, 2023, 7:38 PM

#

So

#

today's lesson: store your acceleration structure data in gpu memory

#

buffer: 102382998272 scratch: 18281826688

#

nvm

#

stoday's lesson

#

implement LODs

devout mesa Aug 11, 2023, 7:55 PM

#

you don't really LOD with RT

dawn wave Aug 11, 2023, 7:56 PM

#

ah

#

well it seems like I can't import the scene because of memory limits

#

shockingly importing 100gb into video memory is a bad idea

devout mesa Aug 11, 2023, 7:58 PM

#

You can actually lower that by a lot

#

just instance your shit

dawn wave Aug 11, 2023, 7:58 PM

#

oh KEKW

#

ill do that

final steeple Aug 11, 2023, 8:19 PM

#

what scenere are u using for 100gigs bleakekw

dawn wave Aug 11, 2023, 8:21 PM

#

he imported an ue5 scene

final steeple Aug 11, 2023, 8:24 PM

#

ue5 nanite gltf

#

KEKW

dawn wave Aug 12, 2023, 12:07 AM

#

bro i feel so fucking stupid

#

i was malding why my transfer buffer wasn't working

#

only to figure out it was because i forgot to include it in my submit info

dawn wave Aug 12, 2023, 4:49 PM

#

Wait what

#

ash::Device is a fucking reference countedp ointer

#

what the fuck

#

BRO

#

IVE BEEN PASSING IT AROUND

#

AS AR EFERENCE

#

THIS WHOLE FUCKING TIME

#

OH MY FUCKING GOD

#

BRO

#

WHY DID NO ONE TELL ME

devout mesa Aug 12, 2023, 4:52 PM

#

dawn wave AS AR EFERENCE

that's good..?

#

why would you needlessly increase the refcount

dawn wave Aug 12, 2023, 4:52 PM

#

nono

#

like all my very light abstraciton layers for vulkan

#

all required me to pass in a device

#

for everything

#

bleakekw

#

i could've just cloned the device

#

and stored it onto the struct

#

huh

#

seems like phobos also stores it in their structs. they put device into their structs as well

feral trellis Aug 12, 2023, 7:46 PM

#

Yep

#

Good ol Arc<T>

#

(internally that's what phobos does at least)

dawn wave Aug 12, 2023, 9:55 PM

#

brain dead mode time

#

so like what does x' mean

#

the derivative of x?

#

bro im too dumb 😭

#

fuck man i need to review grade 12 calc

#

might as well to prep for uni

devout mesa Aug 12, 2023, 10:05 PM

#

it's another variable

#

you could write t or something

dawn wave Aug 12, 2023, 10:06 PM

#

ahhhh why tf are they using x'

#

god dammit math

devout mesa Aug 12, 2023, 10:06 PM

#

it's just another way

oh the value of the intregral KEKW

i'm stupid

devout mesa Aug 12, 2023, 10:46 PM

it's just another variable bro

they used x' instead of x because x is already used somewhere else (in the bounds of the integral)

it's just to let you know that this x and the other x are NOT the same

imo you should reject all gpus that do not meet your requirements

ideally you can also have a device selector witin the app

this is bikeshedding 532.0

when handling queues and logical devices

do you guys just combine them together?

i.e. have a queue struct, but have it all stored in the logical device

or do you guys just make it a seperate class

also we need a name for this library

depends on the library youre using

so like uh how would I make a rendergraph...

#

https://blog.traverseresearch.nl/render-graph-101-f42646255636

Medium

Render Graph 101

Designing an efficient renderer can be quite a tough task. Especially with the new low-level graphics APIs like DirectX 12 and Vulkan where…

#

maybe wpotrick is cooking something

#

wait tf is a task graph?

tropic vigil Dec 24, 2023, 6:37 PM

#

a graph of tasks

#

nodes are tasks

#

edges are dependencies between tasks

#

if node A uses the output of node B, then theres i a (directed) edge from node B to node A (or the other way around, you can choose this)

#

In a render graph, the inputs and outputs become gpu resources such as attachments and buffers

#

The nodes could be renderpasses, but they dont have to be

dawn wave Dec 27, 2023, 12:41 AM

#

huh alright

#

this makes sense now

#

it can't be that hard

#

(im about to go on a 5 year journey on a scale never seen before in history)

tropic vigil Dec 27, 2023, 8:55 AM

#

Conceptually it’s not, implementing it without bugs and with proper sync is a bit more work :)

dawn wave Dec 28, 2023, 9:40 PM

#

huh alright

#

another question, why do you re-export all the wsi + ash types?

#

prelude.rs

#

since i would assume you could just state in crates.toml a hard coded version phobos is made for (ash and wsi)

dawn wave Dec 28, 2023, 10:23 PM

#

also really dumb question

#

uhh why does Device.rs in phobos but Arc<> but not Instance should they not both use it to ensure that Drop doesn't get called too early?

dawn wave Dec 28, 2023, 11:00 PM

#

im kinda lost now how tf ash destroys and cleans vulkan objects? Drop I assume immedietly causes a cleanup of a vulkan object?

#

fuck it

#

what if i just wrapped it all in Arc<>

#

#[derive(Clone)]
pub struct Instance {
    pub entry: Arc<ash::Entry>,
    pub instance: Arc<ash::Instance>,
}

devout mesa Dec 28, 2023, 11:17 PM

#

wrapping vulkan objects in a shared pointer sounds very wrong

dawn wave Dec 28, 2023, 11:18 PM

#

yeah feels like so

#

#[derive(Clone)]
pub struct Instance {
    pub entry: ash::Entry,
    pub instance: ash::Instance,
}

impl Drop for Instance {
    fn drop(&mut self) {
        unsafe {
            self.instance.destroy_instance(None);
        }
    }
}

let instance = Arc::new(Instance { ... });

dawn wave Dec 28, 2023, 11:51 PM

#

nah, i'd wrap it all in Arc<>

#

bleakekw

#

Infinite overhead

dawn wave Dec 29, 2023, 12:59 AM

#

@devout mesa how do you handle managing the lifetimes of vulkan objects?

#

im 100% overthinking this problem

my assumption was to just throw reference counters everywhere then have the destructor that destroys the vulkan object itself

what is this sentence

#

💀

dawn wave Dec 29, 2023, 10:15 PM

#

tropic vigil what is this sentence

💀 oh ok i figured it out

#

why does the handle of device.rs using Arc<>

#

but literally everything else doesn't

tropic vigil Dec 29, 2023, 10:16 PM

#

i think

dawn wave Dec 29, 2023, 10:16 PM

#

I'm just really lost on how Phobos ensures lifetimes as I don't see phobos making use of reference counting for other stuff

tropic vigil Dec 29, 2023, 10:16 PM

#

arc is refcounting

#

but uh

#

device is used kinda everywhere

#

so its easier to just refcount it

#

for most other objects i rely on the user to create them in the right order

theres also nothing stopping you from doing that in user code

tropic vigil its not no

since i doubt im making millions of vulkan objects at once

#

but theres no reason the library should enforce that

dawn wave "yeah bro it isn't that bad you just gotta make these 11 vulkan objects which on...

you make structs

with sane defaults

and let the user only change what they need

vulkan.h is not typesafe and vulkan.hpp is a scam

dynamic rendering 😎

#

its time to vkguide 2.0.

dawn wave Dec 29, 2023, 11:31 PM

#

nah i forgot how to even do dynamic rendering 💀

#

no i figured it out

#

so uh do you guys combine the renderpass and pipeline

#

or keep them seperated?

devout mesa Dec 29, 2023, 11:33 PM

#

they have no relationship

#

besides a single handle that you need for pass compatibility

#

just do dynamic rendering

dawn wave Dec 29, 2023, 11:34 PM

#

ok o7

#

i uh kinda forgot how to enable extensions again 💀

#

i just attach the features in the .pNext chain yeah of physical device features?

#

wait so can extensions be enabled from the device + instance or must they only be enabled from only one?

devout mesa Dec 29, 2023, 11:53 PM

#

instance extensions are mostly deprecated

#

use device extensions only

dawn wave Dec 29, 2023, 11:53 PM

#

yeah

#

uh

#

wait no im good

devout mesa Dec 29, 2023, 11:54 PM

#

also you don't need an extension for dynamic rendering

#

it's core in 1.3

dawn wave Dec 29, 2023, 11:54 PM

#

oh

#

bleakekw

#

eh who cares

#

good exercise

#

wait i have an issue

#

uh my device suitability checks

#

need a surface but that also enables the extensions there

#

bleakekw

#

do i just seperate it into two stages:
first one just checks extension support
the second checks for surface support?

#

i guess i have to bite the bullet

#

and accept instance extensions for just this

dawn wave Dec 30, 2023, 1:12 AM

#

uh when doing dynamic rendering would I still need to make my attachments descriptions?

dawn wave Dec 30, 2023, 2:36 AM

#

god dammit

#

i forgot to enable dynamic rendering

#

bleakekw

dawn wave Dec 30, 2023, 8:39 PM

#

so like should i just do this in hlsl KEKW or stay in glsl

devout mesa Dec 30, 2023, 8:58 PM

#

do NOT do HLSL

dawn wave Dec 30, 2023, 9:07 PM

#

near fern Dec 30, 2023, 9:08 PM

#

bad buffers

dawn wave Dec 30, 2023, 9:09 PM

#

huh

#

okay

near fern Dec 30, 2023, 9:09 PM

#

but byte address buffers are fine

#

mostlz

#

im used to them from work

#

i think its ok IF you know what to do to be fast

devout mesa Dec 30, 2023, 9:24 PM

#

dawn wave why :(

dxc ignores you

#

buffers are garbage

#

no BDA

#

tons of perf pitfalls

#

just don't

dawn wave Dec 31, 2023, 1:04 AM

#

do you guys uh

#

use timeline semaphores for swapchain?

#

wait you can't
