You can probably look up PBR (Physically Based Rendering) implementation in OpenGL if that's what you're looking for. If you just want some simple shaders, TrippyGL has a a builder that allows making some basic shaders similar to MonoGame's BasicEffect: https://github.com/SilkCommunity/TrippyGL/blob/master/TrippyGL/SimpleShaderProgramBuilder.cs

You can definitely take some code from there and make it return just the GLSL code strings

F

flykeOP•1/10/23, 10:17 PM

Yes, PBR materials would be the best, because its standard for game assets.

F

flykeOP•1/10/23, 10:21 PM

Will look closely at that TrippyGL, I found it before but not quite understand what it doing, and Discord not very populated.

Furball•1/11/23, 7:41 PM

okay so

F

Furball•1/11/23, 7:41 PM

fun issue

F

Furball•1/11/23, 7:41 PM

glfwShowWindow is causing a access violation

F

Furball•1/11/23, 7:41 PM

assuming im reading the stack trace correctly

P

Perksey•1/11/23, 7:41 PM

nope

P

Perksey•1/11/23, 7:42 PM

given your reaction this doesnt seem like its the first time its happening

P

Perksey•1/11/23, 7:46 PM

i mean

P

Perksey•1/11/23, 7:46 PM

it is and it isn't

P

Perksey•1/11/23, 7:46 PM

it is in that glfwShowWindow has never failed before

P

Perksey•1/11/23, 7:47 PM

but it isn't in that i fucking hate it when glfw is the problem it's always so difficult to figure out

P

Perksey•1/11/23, 7:47 PM

are you running in rosetta or native

P

Perksey•1/11/23, 7:48 PM

(i presume native based on

ARM-64 (Native)

Lyris the Kitori•1/11/23, 7:49 PM

macos can mix and match, that only means dotnet was native arm

L

Lyris the Kitori•1/11/23, 7:50 PM

you can also try to rebuild glfw with debug symbols so we get line numbers

P

Perksey•1/11/23, 7:51 PM

ah ok

P

Perksey•1/11/23, 7:51 PM

it looks like we don't check whether glfwCreateWindow returns null

P

Perksey•1/11/23, 7:53 PM

@furball.vixie do you want a super super easy community contribution

F

Furball•1/11/23, 7:54 PM

what is it

P

Perksey•1/11/23, 7:55 PM

in Glfw.cs we have

        public static GlfwCallbacks.ErrorCallback ErrorCallback { get; } = (errorCode, description) =>
        {
            var ex = new GlfwException($"{errorCode}: {description}") { ErrorCode = errorCode };
            if (_isWindows)
            {
                // we can actually be helpful on windows which is cool
                throw ex;
            }

            // ffs
            _exceptions.Add(ex);
        };

        public static GlfwCallbacks.ErrorCallback ErrorCallback { get; } = (errorCode, description) =>
        {
            var ex = new GlfwException($"{errorCode}: {description}") { ErrorCode = errorCode };
            if (_isWindows)
            {
                // we can actually be helpful on windows which is cool
                throw ex;
            }

            // ffs
            _exceptions.Add(ex);
        };

        public static GlfwCallbacks.ErrorCallback ErrorCallback { get; } = (errorCode, description) =>
        {
            var ex = new GlfwException($"{errorCode}: {description}") { ErrorCode = errorCode };
            if (_isWindows)
            {
                // we can actually be helpful on windows which is cool
                throw ex;
            }

            // ffs
            _exceptions.Add(ex);
        };

        public static GlfwCallbacks.ErrorCallback ErrorCallback { get; } = (errorCode, description) =>
        {
            var ex = new GlfwException($"{errorCode}: {description}") { ErrorCode = errorCode };
            if (_isWindows)
            {
                // we can actually be helpful on windows which is cool
                throw ex;
            }

            // ffs
            _exceptions.Add(ex);
        };

Perksey•1/11/23, 7:55 PM

your mission, should you choose to accept it, is to litter a bunch of

Glfw.ThrowExceptions();

Glfw.ThrowExceptions();

Glfw.ThrowExceptions();

Glfw.ThrowExceptions(); calls in

GlfwWindow

GlfwWindow

GlfwWindow

GlfwWindow where you think it makes sense

Is there an API reference for Silk.NET? The site https://dotnet.github.io/Silk.NET/docs/silk.net/ is basically blank. My current Google searches are showing me the samples or examples I'm looking for.

Silk.NET - High-Speed & Advanced .NET Graphics & Compute

Miscellaneous

L

Lyris the Kitori•1/12/23, 12:35 AM

API reference for what specifically

L

Lyris the Kitori•1/12/23, 12:35 AM

our bindings are very similar to the C APIs, so any docs or tutorials for those will apply here

R

Raphaël•1/12/23, 12:36 AM

Well, in part I'm looking to learn what I can do. In particular, looking if there is a way to open a file dialog window.

L

Lyris the Kitori•1/12/23, 12:36 AM

that would be outside the realm of Silk.NET, you want a full GUI toolkit for that

L

Lyris the Kitori•1/12/23, 12:36 AM

Eto.Forms, Avalonia, GTKSharp are all good choices

R

Raphaël•1/12/23, 12:37 AM

Ok, thanks!

F

flykeOP•1/12/23, 7:53 AM

You could add a small article, “how to appy C docs to Silk.Net”, because I had exactly same question, yes “API” is similar, but random users dont know where to start. For example, I know “Feature X” from C is present in C# library, how to use ? X no idea

L

Lyris the Kitori•1/12/23, 7:53 AM

you use it in generally in the exact same way

L

Lyris the Kitori•1/12/23, 7:54 AM

the C concepts apply usually 1:1, so if you know C you know how to use Silk APIs for the most part

F

flykeOP•1/12/23, 7:58 AM

And if I know exact C lib name, I can include it in dummy C project in Visual Studio, and read all docstrings? Is is the correct way?

L

Lyris the Kitori•1/12/23, 7:58 AM

what

L

Lyris the Kitori•1/12/23, 7:58 AM

you just google it

F

flykeOP•1/12/23, 8:00 AM

Yes, or check online docs. For me local descriptions in IDE are more convinient, and faster.

H

Hanprogramer•1/12/23, 12:13 PM

silk doesn't even have online docs

H

Hanprogramer•1/12/23, 12:13 PM

use intellisense

HHanprogramer silk doesn't even have online docs

L

Lyris the Kitori•1/12/23, 12:13 PM

we are talking about C APIs silk binds to

H

Hanprogramer•1/12/23, 12:13 PM

ohhhh

P

Perksey•1/12/23, 12:14 PM

all the people asking for an online API reference don't know what they're asking for - it'd be terrible with the amount of functions/overloads we have

P

Perksey•1/12/23, 12:14 PM

"ah yes i want an entire page dedicated to just D2D1GetGradientMeshInteriorPointsFromCoonsPatch"

H

Hanprogramer•1/12/23, 12:15 PM

yeah

Is it possible to find some premade shaders for GL? Like “lit/unlit material” same as we have in Uni
