SilkMarshal.PtrToString

~~Hmmm that seems to be returning a string representation of the pointer itself? I get 139814784783936~~

Lyris the Kitori•4/10/23, 1:45 AM

what?

M

MachinariusOP•4/10/23, 1:45 AM

I should really read the funciton signature

I am dum dum. I was WriteLine'ing the pointer, not the resolved string

ah

It works, thank you!

Ended up with this little helper to enable debug output:

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

I am a bit stuck on tutorial 3.2, I am getting very different lighting outputs. My code seems to somehow calculate lighting for all faces, while the tutorial code is lighting only the face that is directly in front of the light

M

M

MachinariusOP•4/10/23, 2:52 AM

Not sure why. I've checked that my shaders do the same, the vertexes and normals were straight-up copied

M

MachinariusOP•4/10/23, 2:53 AM

Any ideas would be greatly appreciated

This is the commit that introduced that lighting, in case anyone wants to give it a look https://github.com/Machinarius/Custom3dEngine/commit/203a1cf3a286d528c2052496dd658e7b9e01c54b

this seems to be an issue with your vertex normals..? being incorrect? thats my guess

i am experiencing a problem running the wgpu examples at https://github.com/dotnet/Silk.NET/tree/main/src/Lab/Experiments

the

libwgpu_native.so

libwgpu_native.so file is copied to the

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so folder, but the webgpu backend can only find it if i copy it manually to the root of the build folder

when building projects that reference other projects by files, libs arent copied around properly

L

Lyris the Kitori•4/10/23, 7:14 AM

its a dotnet thing

theres no fix

just copy it manually

also those arent examples, if you read the README file in src/Lab/

You were right. I was using a mesh with UV data instead of normal data. Late-night coding is one hell of a drug

I ported my pc-side renderer to the Android platform, and encountered a problem: the screen is completely black. I tried to use renderdoc to capture the frame and found that the output vertex data of the vertex shader could not be obtained.

Filiph Siitam Sandström•4/13/23, 12:38 PM

Any good high-level graphics libraries to recommend? Even as a kernel developer this is just way too low level.
Like if I want to draw a cube it should be a simple as

api.DrawCube(size, pos, texture)

api.DrawCube(size, pos, texture)

api.DrawCube(size, pos, texture)

api.DrawCube(size, pos, texture), things like vertices, indices should just be abstracted away

monogame or something

opengl isnt that low level tbh
