speaking of we really need to delete Silk.NET.OpenGL.Legacy when

grDrawTriangle

Machinarius•4/8/23, 2:34 PM

Ok I finally understand! You can pack multiple bits of data in the vertex data like coordinates and base colors, and then tell OGL how to map that to the different positionposition values in the shader!

Aqua•4/8/23, 2:35 PM

yep

Machinarius•4/8/23, 2:36 PM

I was struggling with the example code having stride 77 until I saw it packing XYZ + RGBA on a single row

Machinarius•4/8/23, 2:46 PM

Does this abstraction make sense?

أأمير الدخميسي ahhhhhhhhhhh i very bad in engligh

أمير الدخميسي•4/8/23, 2:53 PM

everyone here able to that

MasterMan•4/8/23, 3:37 PM

How do I check the ComPtr<> object for validity? With regular pointers it's simple, but with a wrapper I've no idea
Google gives this (screenshot), but it's not valid in Silk.net

chairclr•4/8/23, 3:44 PM

you could just check ComPtr<`1>.Handle

PerkseyOP•4/8/23, 4:04 PM

yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool

MasterMan•4/8/23, 4:24 PM

That works, yeah
Though cast would help, since currently the check requires an unsafe block

PPerksey yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool 🤔

khitiara•4/8/23, 4:25 PM

better yet you can override the true and false operators

PerkseyOP•4/8/23, 4:25 PM

what

PerkseyOP•4/8/23, 4:25 PM

this scares me

khitiara•4/8/23, 4:25 PM

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/true-false-operators

true and false operators - treat objects as Boolean values

Learn about the C# truetrue and

false

false

operators. Overload these operators to treat your type as a Boolean value

PerkseyOP•4/8/23, 4:26 PM

WHY IS THIS A THNG SWEET JESUS

khitiara•4/8/23, 4:26 PM

maybe also unary ! operator too idk

PerkseyOP•4/8/23, 4:26 PM

so if the implementation is crap you could actually have (thing && !thing) == true(thing && !thing) == true

khitiara•4/8/23, 4:27 PM

yes

PPerksey WHY IS THIS A THNG SWEET JESUS

khitiara•4/8/23, 4:27 PM

this is the appropriate reaction imo lol

khitiara•4/8/23, 4:27 PM

idk where i learned about this cursed stuff but there ya go

Howie•4/8/23, 4:28 PM

double barrel foot gun there!

khitiara•4/8/23, 4:28 PM

as for why its a thing probably something to do with implicit casts and stuff like the ?: operator not working nicely, idk

khitiara•4/8/23, 4:29 PM

that thing has been in the spec since at least 2011 probs earlier

MasterMan•4/8/23, 4:34 PM

Either override the ! operator, or add an "IsValid" function, or both

khitiara•4/8/23, 4:35 PM

the real answer is to just add an IsValid property yeah

PerkseyOP•4/8/23, 4:35 PM

yeah i think so too

PerkseyOP•4/8/23, 4:58 PM

though cursed "dylan's 3.0 headcannon" fact: I am currently thinking of adding a NullPtrNullPtr type that can be used to check all this. basically i want 3.0 (in my head, this isn't official yet) to be super seamless to interact with from C# but there's just some things we can't do in the language, so silk.net.core would contain a mini DSL that makes working with unsafe better

PerkseyOP•4/8/23, 4:58 PM

i.e. you could do

var x = (int*)1;
Ptr<int> y = (int*)2;
var z = new ComPtr<IUnknown>((IUnknown*)3);
Console.WriteLine(x == nullptr);
Console.WriteLine(y == nullptr);
Console.WriteLine(z == nullptr);

var x = (int*)1;
Ptr<int> y = (int*)2;
var z = new ComPtr<IUnknown>((IUnknown*)3);
Console.WriteLine(x == nullptr);
Console.WriteLine(y == nullptr);
Console.WriteLine(z == nullptr);

khitiara•4/8/23, 4:59 PM

not a bad idea tbh

PerkseyOP•4/8/23, 5:02 PM

basically they made a massive mistake making global using static Silk.NET.Core.DSL.SilkDSL;global using static Silk.NET.Core.DSL.SilkDSL; possible

PerkseyOP•4/8/23, 5:02 PM

because unless the user turns it off, we can decorate the C# language with a bunch of new """keywords""" that are tailored to unsafe uses

PPerksey here's a cursed prototype i came up with just now <https://sharplab.io/#v2:CYLg1...

TechPizza•4/8/23, 7:01 PM

oh no, a static readonly instead of a static property when

TechPizza•4/8/23, 7:01 PM

i actually ported msvc std source to c# with a Ref<T>Ref<T> helper lol

TechPizza•4/8/23, 7:02 PM

it was basically a refref that acted as a pointer

TTechPizza i actually ported msvc std source to c# with a `Ref<T>` helper lol

PerkseyOP•4/8/23, 7:18 PM

Yeah this is basically what I’m thinking, but I just need to figure out how we can have a Ref-like struct in a non-ref struct

PerkseyOP•4/8/23, 7:19 PM

otherwise you can’t have Ptr<VkBaseOutStructure> and other common patterns

FFurball dxvk exists but idk if the developer experience on linux would be great

Lyris the Kitori•4/8/23, 8:17 PM

you have access to renderdoc and a debugger, so it's really workable

PPerksey you awoken the era of graphics i've been trying to pretend doesn't exist 😂

if you think about it FFP is better than modern OpenGL as it has display lists

Lyris the Kitori•4/8/23, 9:13 PM

so its basically vulkan with command lists

PerkseyOP•4/8/23, 9:13 PM

NO BAD

PPerksey NO BAD

Lyris the Kitori•4/8/23, 9:13 PM

OKAY BUT DISPLAY LISTS IN MODERN OPENGL WOULD BE SO NICE
